- 0:00Did you know that even with the most advanced
- 0:02surgery, a really significant number of hip socket
- 0:04fractures, particularly in our older patients,
- 0:07might still end up needing a total hip replacement?
- 0:10We're talking about injuries that don't just
- 0:12break a bone. They fundamentally change a patient's
- 0:14mobility, their quality of life. It's this impact
- 0:17and the often quite counterintuitive complexities
- 0:20that we're here to unravel today. Welcome to
- 0:22the Depth Dive, the show where we aim to extract
- 0:25essential knowledge and hopefully some surprising
- 0:27insights from complex medical topics. Today,
- 0:30we're taking a deep dive into acetabular fractures,
- 0:32those critical breaks right in the hip's vital
- 0:35socket. These aren't just any fractures. They
- 0:38demand, well, a really nuanced understanding,
- 0:40meticulous decision making, and often highly
- 0:42specialized care. And joining us to unpack this
- 0:45intricate area, drawing from vast clinical experience
- 0:48and the latest research, is a true luminary in
- 0:51the field. He's a consultant orthopedic surgeon
- 0:53at the Royal London Hospital, specializing in
- 0:55pelvis, acetabular, and revision arthroplasty.
- 0:58He's also the founder of OrthoGlobe, an international
- 1:00collaborative dedicated to advancing musculoskeletal
- 1:03practice through global research. A very warm
- 1:06welcome. Thank you very much for having me. It's
- 1:08a real pleasure to be here to talk about this.
- 1:10It's our absolute privilege. So let's kick things
- 1:12off with a bit of a rapid fire segment just to
- 1:15set the stage for our deep dive. For those in
- 1:18our audience who might perhaps sometimes lump
- 1:20all hip or pelvic injuries together, what's the
- 1:23fundamental difference that really defines an
- 1:25acetabular fracture and why is spotting that
- 1:28distinction so critical for outcomes? That's
- 1:30a great question to start with. The fundamental
- 1:32distinction and it really dictates everything
- 1:35that follows is that an acetabular fracture inherently
- 1:38involves the articular surface of the hip joint,
- 1:41the cartilage. The joint surface itself. Exactly.
- 1:44Unlike many pelvic ring fractures, which might
- 1:46affect the structural integrity of the pelvis,
- 1:49but often spare the joint itself, an acetabular
- 1:52fracture directly impacts that smooth cartilage
- 1:56line socket where the femoral head moves. And
- 1:58this direct involvement of the joint surface
- 2:00is absolutely paramount. because it's the primary
- 2:04determinant of post -traumatic osteoarthritis
- 2:06down the line. If that articular surface isn't
- 2:09restored almost perfectly, the joint mechanics
- 2:12are disrupted. That leads to progressive wear
- 2:14and tear. pain, stiffness, and ultimately what
- 2:18we sometimes call the death of the hip, meaning
- 2:20it needs replacing. So it really is all about
- 2:22that critical joint integrity, that surface smoothness,
- 2:25knowing that if we look at the bigger picture,
- 2:28epidemiologically speaking, who is most vulnerable
- 2:31to these injuries and what sort of forces are
- 2:33typically causing them? Well, acetabular fractures
- 2:35show quite a fascinating bimodal distribution.
- 2:38So we see peaks in two very distinct age groups.
- 2:41Right. In younger patients, typically those between,
- 2:44say, 20 and 39 years old, and this group actually
- 2:47made up over half the patients in one large study,
- 2:50these are overwhelmingly high energy injuries.
- 2:52Road traffic accidents are a major cause, accounting
- 2:54for nearly 57 % in that same study. You have
- 2:57to think of that classic dashboard injury, where
- 2:59the knee hits the dashboard, driving the femoral
- 3:02head backwards forcefully into the acetabular
- 3:04socket. Then, in stark contrast, the other peak
- 3:07occurs in our elderly patients. Here, it's typically
- 3:11low energy falls, often just from a standing
- 3:13height that caused the fracture. And this is
- 3:16primarily due to weakened bone quality from osteoporosis.
- 3:19The precise force vector, you know, the direction
- 3:22of the impact and the position of the femoral
- 3:24head at that exact moment, abduction, adduction
- 3:26rotation, they're absolutely key in determining
- 3:30the specific fracture pattern we see. It's quite
- 3:32remarkable how the mechanism shifts so dramatically
- 3:34with age. So finally, just to frame our discussion
- 3:38today, in a single sentence, what would you say
- 3:40is the biggest challenge you personally face
- 3:42when you're approaching the management of an
- 3:44acetabular fracture, particularly in our more
- 3:46senior patients? Hmm, in senior patients? I'd
- 3:50say the single biggest challenge is reliably
- 3:53achieving and crucially maintaining stable fixation
- 3:57in bone that's often highly comminuted, shattered
- 3:59into many pieces, and osteoporotic. And that
- 4:03task is compounded by their significant medical
- 4:05comorbidities, which ultimately impacts their
- 4:08ability to mobilize afterwards and recover effectively.
- 4:11It's a complex interplay. That sets the stage
- 4:13perfectly for the complexity we're diving into.
- 4:15Let's really unpack the hip joint itself then.
- 4:18To genuinely grasp these fractures, we need to
- 4:20understand the, well, the architectural marvel
- 4:23that is the acetabulum. When you visualize the
- 4:25hip, what's the architectural blueprint that
- 4:27immediately comes to mind when considering these
- 4:29fractures? What are those critical anatomical
- 4:32elements a surgeon just has to understand? Well,
- 4:34when I think of the hip joint, I immediately
- 4:36picture this beautifully engineered ball and
- 4:39socket system. Yeah. It's quite elegant, really.
- 4:41Yes. The ball is the femoral head, the top end
- 4:44of the thigh bone, and the socket is the acetabulum,
- 4:47which is an integral part of the pelvis itself.
- 4:49What makes the acetabulum so intricate and why
- 4:52injuring it is so challenging is its highly specific
- 4:55structural complexity. Both the femoral head
- 4:57and the acetabulum are covered with articular
- 5:00cartilage. That smooth surface. Exactly. This
- 5:03incredibly smooth, almost frictionless substance
- 5:06is absolutely critical. It allows the bones to
- 5:09glide effortlessly, facilitating movement without
- 5:11friction or pain. And surrounding this, you have
- 5:14strong ligaments, tough bands of tissue that
- 5:16provide stability, whilst allowing an extensive
- 5:19range of motion without dislocation. But perhaps
- 5:21the most fundamental concept, particularly for
- 5:23surgical planning, is the Judet and Lateral Column
- 5:26Theory. It's the bedrock of how we think about
- 5:28these fractures. Right, the two columns. Precisely.
- 5:31They conceptualize the acetabulum as being supported
- 5:34by two main columns, forming an invented Y shape,
- 5:38almost like structural scaffolding holding the
- 5:40socket up. The anterior column is the more extensive
- 5:44one. It traces from the anterior iliac spines
- 5:46along the iliac wing and connects down to the
- 5:49pubic rami. The posterior column, in contrast,
- 5:53is a bit more limited structurally. It extends
- 5:55from the sciatic notch and runs down through
- 5:57the ischium. Understanding these columns is absolutely
- 6:00vital because fracture patterns aren't just random
- 6:02cracks. They typically involve breaks along or
- 6:06between these fundamental structural supports.
- 6:08So the fractures follow these lines of force,
- 6:10essentially? In a way, yes. And when we look
- 6:13at x -rays, we're not just glancing. We're meticulously
- 6:15searching for specific radiographic landmarks
- 6:18that help us delineate these columns and assess
- 6:20the fracture. Key among these are the ileopectinale
- 6:22line, which essentially represents the integrity
- 6:25of that anterior column. and the ilioeschial
- 6:27line, which signifies the posterior column. You
- 6:31also look for the radiographic teardrop, indicating
- 6:33the medial wall, and the radiographic roof that's
- 6:36the crucial weight -bearing dome. It's important
- 6:39to remember these lines aren't literal cracks
- 6:41themselves. They're overlapping condensations
- 6:43of cortical bones seen on the 2D image. But they
- 6:46offer critical clues about the underlying 3D
- 6:49structural integrity. I see. And what about the
- 6:51surrounding structures, nerves? blood vessels.
- 6:54Yes. From a surgeon's perspective, perhaps nothing
- 6:56is more critical than the vascular and neurovascular
- 6:59considerations. There's a particularly precarious
- 7:02anastomosis, a connection between blood vessels
- 7:04often rather dramatically dubbed the coronamortis,
- 7:07the crown of death. This involves vessels from
- 7:10the external iliac system. like the inferior
- 7:12epigastric artery, and the internal iliac system,
- 7:15like the obturator vessels. This area is highly
- 7:19susceptible to injury during certain surgical
- 7:21approaches, particularly anterior ones. Significant
- 7:24bleeding can occur very quickly if it's damaged.
- 7:27And perhaps even more importantly, major nerves,
- 7:30most notably the sciatic nerve, pass perilously
- 7:33close to the posterior aspect of the hip socket.
- 7:37Extremely close. Damage to this nerve? either
- 7:39from the initial injury itself or unfortunately
- 7:41sometimes during surgery can lead to significant
- 7:44long -term problems like foot drop. That's why
- 7:47we approach this region with such extreme caution
- 7:49and respect. That paints such a clear picture
- 7:52of just how wonderfully complex but also quite
- 7:55vulnerable this structure is. If the femoral
- 7:58head acts like a hammer, as you described earlier,
- 8:00how do these intricate architectural elements
- 8:02then dictate the distinct injury patterns we
- 8:04actually see? It sounds like even a small shift
- 8:07in force or femur position could lead to a vastly
- 8:09different fracture. You've hit on a crucial point
- 8:11there. The path of physiology is precisely that
- 8:14forces are transmitted through the femoral head,
- 8:17which really does act like a hammer striking
- 8:19the acetabulum. And the exact position of the
- 8:22femur at the moment of impact, whether it's adducted
- 8:26closer to the midline, abducted away from the
- 8:28midline, or rotated and the precise direction
- 8:32of the force are absolutely critical in determining
- 8:35the specific fracture pattern and the amount
- 8:37of displacement. It's not random at all. Can
- 8:40you give some examples? Sure. Let's take that
- 8:42common dashboard injury again. If the knee strikes
- 8:44the dashboard, it drives the femoral head directly
- 8:46backwards against the acetabulum. This frequently
- 8:49results in a posterior wall fracture. That's
- 8:51actually the most common pattern overall. Right.
- 8:53Falls directly onto the side of the hip. transmitting
- 8:55force from the side can also cause these. And
- 8:58we differentiate fundamentally between high -energy
- 9:01trauma, typically seen in younger adults, the
- 9:04road accidents, the major falls. Exactly. Which
- 9:08not only causes significant bone fragmentation,
- 9:11but also extensive soft tissue damage, internal
- 9:13bleeding, and potential lacerations of major
- 9:16blood vessels or nerves. These patients often
- 9:18present with multiple associated injuries. That
- 9:21Jordan's study again noted over half of 53 .9
- 9:24percent had other serious injuries needing attention
- 9:27head chest abdomen a major trauma scenario Absolutely
- 9:31in contrast you have low energy trauma more common
- 9:34in our elderly patients This causes fractures
- 9:37because the bone quality is severely weakened
- 9:39primarily due to osteoporosis Whilst the energy
- 9:42is lower, the compromised bone makes stable surgical
- 9:45fixation exponentially more challenging. It's
- 9:47fascinating how the energy level ties into age
- 9:49and bone health. Given this wide spectrum, how
- 9:52do orthopedic professionals actually categorize
- 9:55these fractures? How do you standardize communication
- 9:57and, importantly, guide treatment decisions?
- 10:00Is there a sort of universal language? Yes, there
- 10:03is, thankfully. To bring order and a common language
- 10:06to this complexity, the Judet -Laternal classification
- 10:09is without doubt the most widely accepted and
- 10:11foundational system. It's really the framework
- 10:13we all use when discussing acetabular fractures.
- 10:16It systematically divides fractures into two
- 10:18main types, five elementary patterns and five
- 10:21associated patterns. I'd say five of each. Exactly.
- 10:24The five elementary patterns involve essentially
- 10:26a single main fracture line dividing the acetabulum.
- 10:30First, the posterior wall fracture. As we said,
- 10:33the most common overall, making up almost 38
- 10:35% of cases in the Jordan study often linked to
- 10:37those dashboard injuries. Second, the posterior
- 10:40column fracture involving that larger posterior
- 10:42structural support. Third, the anterior wall
- 10:46fracture. This is quite rare on its own. It often
- 10:48presents more as part of a complex pelvic ring
- 10:50injury or is associated with an anterior hip
- 10:53dislocation. Fourth, the anterior column fracture
- 10:56involving the anterior support. And fifth, the
- 10:58transverse fracture. This is defined as a single
- 11:01fracture line that crosses both the anterior
- 11:03and posterior columns, essentially cutting the
- 11:05acetabulum in half horizontally. Right, those
- 11:07are the elementary ones. What about the associated
- 11:09patterns? The five associated patterns are combinations
- 11:11of these elementary types. They indicate more
- 11:14complex and generally more severe injuries. You
- 11:16have anterior column with posterior hematransverse,
- 11:20posterior column with posterior wall, transverse
- 11:23with posterior wall, Now, this one is actually
- 11:25the most common associated pattern, and importantly,
- 11:28it's linked to the highest incidence of sciatic
- 11:31nerve injury. That's a critical point for prognosis
- 11:34and patient counseling. Definitely. Then there's
- 11:36the T -shaped fracture. This is basically a transverse
- 11:39fracture combined with a vertical split that
- 11:41goes down through the quadrilateral surface in
- 11:43the acetabular fossa, creating that T shape on
- 11:46imaging. And finally, the both -column fracture.
- 11:49This is where both the anterior and posterior
- 11:51columns are completely separated from the intact
- 11:54posterior part of the ilium. All the articular
- 11:57segments, the joint surface pieces, are detached.
- 11:59It's a truly severe injury pattern. And are there
- 12:02specific signs you look for on imaging to help
- 12:05identify these patterns? Absolutely. When we're
- 12:07diagnosing these, we're meticulously looking
- 12:10for specific diagnostic features or signs on
- 12:13the x -rays and CT scans that are almost pathognomonic,
- 12:17meaning if you see them, you know what you're
- 12:18dealing with. For instance, the goal sign. This
- 12:21is seen on the iliac oblique x -ray view and
- 12:24it represents impaction, a crushing injury of
- 12:27the supermedial roof. the top part of the socket.
- 12:30Okay. It's a telltale sign often seen with posterior
- 12:33wall fractures, but critically, it's often a
- 12:35strong, poor, prognostic indicator. It frequently
- 12:39suggests the need for an acute total hip replacement,
- 12:42rather than just fixation, because it signifies
- 12:44significant articular cartilage damage. I see.
- 12:47So that sign carries a lot of weight. It does.
- 12:49Another crucial sign is the spur sign, which
- 12:51is visible on the obturator oblique x -ray view.
- 12:54This looks like a sharp spike of intact ilium
- 12:57sticking out laterally, while the entire acetabulum
- 12:59is shifted medially. It's pythognomonic for both
- 13:02colon fractures. It's also vital to understand
- 13:04the concept of secondary congruence, particularly
- 13:07in both colon fractures. You mentioned that earlier.
- 13:10Yes. Despite the acetabulum being completely
- 13:12separated from the axial skeleton, The displaced
- 13:15fragments might deceptively appear to align reasonably
- 13:18well around the femoral head on initial x -rays.
- 13:21It can look falsely reassuring. So it looks okay,
- 13:24but it's actually completely detached. Precisely.
- 13:27It can be profoundly misleading and really underscores
- 13:29the absolute necessity for more advanced imaging,
- 13:32like CT, to truly appreciate the extent of the
- 13:35injury and the instability. And whilst Judelet
- 13:37-Dornel remains the bedrock, we do sometimes
- 13:40briefly consider other systems, like the tile
- 13:42classification, which focuses on overall pelvic
- 13:45stability type C being complex, unstable injuries,
- 13:48or the Young -Burgess classification, which looks
- 13:51at the mechanism of injury. But for the acetabulum
- 13:54specifically, Judelet -Dornel is really our guiding
- 13:56light. That level of detail in classification
- 13:59truly highlights the precision needed. So after
- 14:02identifying the likely pattern, accurate diagnosis
- 14:04is paramount for planning treatment. What are
- 14:07the essential imaging tools you rely on and what
- 14:09are those non -negotiable key findings you're
- 14:11looking for, especially given pitfalls like that
- 14:13secondary concurrence? For accurate diagnosis,
- 14:16we use a very specific sort of stepwise approach
- 14:18to imaging. X -rays are always the initial step.
- 14:21While standard anteroposterior, or AP, views
- 14:24are useful baseline images, the critical views
- 14:27are the specific judit views. We always get these.
- 14:30A two oblique view. Exactly. The obturator oblique
- 14:32view, which profiles the obturator foramen and
- 14:34gives a clear picture of the anterior column
- 14:37and the posterior wall. and the iliac oblique
- 14:39view, which profiles the iliac wing and clearly
- 14:42shows the posterior column and the anterior wall.
- 14:44These specialized views are absolutely essential
- 14:46for visualizing the fracture pattern properly
- 14:48and assessing the degree of displacement, which,
- 14:51as I said, is often not fully appreciated on
- 14:53a standard AP view alone. However, for truly
- 14:57precise management and preoperative planning,
- 14:59computed tomography or CT scams, are unequivocally
- 15:02considered the gold standard. You really can't
- 15:05plan surgery properly without one. Why is CT
- 15:07so crucial? Well, a CT provides exquisitely detailed
- 15:10cross -sectional views of the hip. This is crucial
- 15:13for visualizing subtle injuries that might not
- 15:15be apparent on x -rays, particularly complex
- 15:18posterior injuries or impaction. It defines the
- 15:21fragment size. their exact orientation in 3D
- 15:24space, identifies any subtle marginal impaction,
- 15:28the crushing of the cancellous bone just beneath
- 15:30the articular surface, which affects prognosis,
- 15:33and it detects any intra -articular loose bodies,
- 15:36little bits of bone or cartilage floating in
- 15:38the joint, or articular gaps and step -offs.
- 15:40All of these are critical details for surgical
- 15:42decision -making. You'll simply miss these nuances
- 15:45without a CT. And are there specific measurements
- 15:47you take on these scans? Yes. We look at various
- 15:49things. For instance, we sometimes use measurements
- 15:51like the roof arc angle to try and assess stability.
- 15:55A fracture is generally considered stable if
- 15:56the main fracture line exits outside the primary
- 15:58weight -bearing dome of the acetabulum. This
- 16:01is typically defined as having an angle greater
- 16:03than 45 degrees on the AP and Judith fuse, or
- 16:06it's indicated by seeing an intact subchondral
- 16:08bone ring in the superior 10 millimeters on the
- 16:11axial CT cuts. But you mentioned limitations.
- 16:14Yes. It's crucial to note its limitation in certain
- 16:17fracture patterns, like both column fractures
- 16:20where the whole thing is detached, or some posterior
- 16:22wall fractures. In these cases, there isn't necessarily
- 16:26an intact portion of the acetabulum available
- 16:29for this type of measurement, so you rely on
- 16:31other signs of instability. Beyond static imaging,
- 16:35sometimes we need to dynamically assess stability,
- 16:38particularly for posterior wall fractures. This
- 16:40might involve an examination under anesthesia,
- 16:43or EUA, using fluoroscopy live x -ray. To see
- 16:46how it moves under stress. Exactly. During this,
- 16:50if the medial clear space, the gap between the
- 16:52femoral head and the socket medially opens up
- 16:54under stress, that can be a definitive sign of
- 16:56instability in the posterior wall, which might
- 16:59not have been obvious from the static images
- 17:00alone. And finally, tying back to the urgency,
- 17:04if there's an associated hip dislocation, Early
- 17:07imaging and diagnosis are absolutely critical
- 17:09because as we'll discuss these are surgical emergencies
- 17:11Reduction should ideally occur within 12 hours
- 17:14for improved outcomes Primarily to mitigate the
- 17:17risk of a vascular necrosis death of the bone
- 17:19of the femoral head due to compromised blood
- 17:22supply It's also vital to exclude an associated
- 17:25femoral neck fracture in cases of hip dislocation
- 17:28If there's any doubt whatsoever on the initial
- 17:31x -rays, a CT scan is strongly recommended to
- 17:33rule this out, as finding one would significantly
- 17:36alter the immediate treatment plan, perhaps necessitating
- 17:39a different acute surgical approach altogether.
- 17:42It's clear these injuries demand a rapid, thorough,
- 17:45and incredibly precise diagnostic cascade. Beyond
- 17:48the fracture itself, you've mentioned an associated
- 17:51hip dislocation can be a true orthopedic emergency.
- 17:54What's the immediate priority for a patient presenting
- 17:57like that, and what are the steps you take to
- 17:59manage it acutely? The immediate priority, unequivocally,
- 18:02is to recognize that a fractured acetabulum with
- 18:04a hip dislocation is a surgical emergency. It
- 18:07requires urgent reduction of the dislocated hip.
- 18:10This is not something that can wait. The clock
- 18:12starts ticking immediately to minimize the risk
- 18:14of complications, particularly that of vascular
- 18:16necrosis of the femoral head. Okay, so time is
- 18:19critical. Absolutely. Our initial patient assessment,
- 18:22of course, is always based on Advanced Trauma
- 18:24Life Support or ATLS principles. That means we
- 18:27first prioritize airway, breathing, and circulation
- 18:31of the ABCs to ensure the patient is physiologically
- 18:34stable. Once that's secured, a thorough neurological
- 18:38and vascular assessment of the affected limb
- 18:40is crucial. We must meticulously check for any
- 18:43signs of nerve damage, particularly sciatic nerve
- 18:46injury, which can manifest as foot drop and inability
- 18:49to lift the foot even after the reduction. This
- 18:52assessment guides our immediate next steps and
- 18:55helps us anticipate potential long -term deficits.
- 18:57And the reduction itself. The process of urgent
- 19:00reduction is ideally performed immediately in
- 19:02the emergency department, or RISIS. It requires
- 19:05appropriate sedation, good muscle relaxation,
- 19:08which is key, and often a two -person technique
- 19:10to apply traction and counter -traction safely
- 19:12and effectively. We commonly differentiate between
- 19:15the types of dislocation. Posterior dislocations
- 19:17are the most frequent, often seen with those
- 19:19dashboard injuries. The limb typically presents
- 19:22as shortened, abducted, and internally rotated.
- 19:24And anterior. Anterior dislocations are less
- 19:27common. The limb is typically externally rotated,
- 19:30abducted, and may be slightly flexed. The reduction
- 19:33maneuver is often considered slightly more straightforward
- 19:36due to the shallower anterior wall of the acetabulum,
- 19:40but they can still be challenging. What if you
- 19:42can't reduce it closed? If closed reduction fails
- 19:45in the emergency department, the implications
- 19:47are serious. The patient must be transferred
- 19:50immediately to the operating theater for an open
- 19:52reduction. This should ideally be performed by
- 19:56a hip surgeon, familiar with the necessary approaches,
- 19:59often a posterior approach, and someone who is
- 20:01able to explore the sciatic nerve if there's
- 20:03any concern about entrapment or injury. So specialist
- 20:07input is needed quickly. Yes. It highlights the
- 20:10critical importance of having the right expertise
- 20:12available immediately, day or night. We also
- 20:15have to remember, as we noted from the Jordan
- 20:17study, that more than half 53 .9 % of these patients
- 20:21have other significant body injuries. Right,
- 20:23the polytrauma aspect. Exactly. These can be
- 20:26life -threatening head injuries, chest trauma,
- 20:29abdominal bleeding, other fractures. They require
- 20:32urgent simultaneous attention within a multidisciplinary
- 20:36trauma team setting. It's a comprehensive, coordinated
- 20:39approach that's vital for survival and optimal
- 20:42outcomes. That immediate coordinated response
- 20:45is absolutely critical. But Professor, it's equally
- 20:48important to clarify, as you hinted earlier,
- 20:50that not all acetabular fractures require immediate
- 20:53surgery. When is non -operative management a
- 20:56viable and perhaps even preferable option for
- 20:59these complex injuries? And what does true functional,
- 21:03consumptive care actually look like in practice?
- 21:05It's not just bed rest, is it? No, absolutely
- 21:07not. That's a crucial distinction at a point
- 21:09I often emphasize, particularly when discussing
- 21:11elderly patients. Non -surgical treatment is
- 21:13a viable and often very appropriate option in
- 21:16specific scenarios. We consider it based on both
- 21:18the fracture characteristics and the broader
- 21:20patient factors. Okay, so what fracture types
- 21:22might be suitable? For fracture characteristics,
- 21:25we look for minimally displaced fractures, generally
- 21:27meaning the displacement is less than two millimeters
- 21:30on all views. Certain stable fractures, perhaps
- 21:33some isolated anterior column or anterior wall
- 21:36fractures, can also be managed non -operatively
- 21:39if the joint remains congruent. And crucially,
- 21:42Some associated both column fractures can exhibit
- 21:45what we call secondary congruency. Remember that?
- 21:48Yes, where it looks aligned despite being detached.
- 21:51Exactly. Where, despite the fragments being significantly
- 21:54displaced relative to the rest of the pelvis,
- 21:57they maintain a relatively stable articulation
- 21:59around the femoral head itself. In these select
- 22:02cases, even with significant displacement from
- 22:04the pelvic ring, the hip joint might still function
- 22:07acceptably without surgery, avoiding major operation.
- 22:10Lastly, highly combinated fractures, very shattered
- 22:13and severely osculoporotic bone might also be
- 22:16better suited for conservative management. This
- 22:19is because attempting surgical fixation in such
- 22:21poor quality bone can be technically very difficult,
- 22:24unreliable, and prone to failure, potentially
- 22:26causing more harm than good. And what about patient
- 22:28factors? Patient factors are equally, if not
- 22:32more important, especially in the geriatric population.
- 22:35We strongly consider non -operative management
- 22:38for patients who are at a very high risk for
- 22:40surgical complications due to significant comorbidities.
- 22:44things like severe uncontrolled heart disease,
- 22:47advanced lung disease, poorly controlled diabetes,
- 22:50perhaps advanced dementia, or those with severely
- 22:52limited pre -injury mobility who simply may not
- 22:55tolerate extensive surgery and the demanding
- 22:57rehabilitation afterwards. Makes sense. Also,
- 23:00patients presenting late, say, more than three
- 23:03weeks after the injury where the fracture has
- 23:05already started to stick or partially healed
- 23:07with fibrous tissue may also be candidates. Delayed
- 23:10surgery in these cases can be exponentially more
- 23:13challenging and fra - with complications like
- 23:14infection or nerve injury. And finally, sometimes
- 23:17surgical factors play a role. If there's a lack
- 23:20of available multidisciplinary expertise locally
- 23:22to offer complex reconstructive surgery safely
- 23:25and effectively, then conservative management
- 23:27might indeed be the more prudent and ethical
- 23:29choice for that patient in that setting. So if
- 23:31non -operative is chosen, what does that involve?
- 23:34Definitely not just lying in bed. Absolutely
- 23:36not. Modern functional conservative treatment
- 23:39is far from passive bed rest. It demands a comprehensive,
- 23:42proactive, multidisciplinary team approach. This
- 23:46absolutely has to include specialist physiotherapists
- 23:48guiding early, safe movement, excellent nursing
- 23:52care focusing on skin integrity, nutrition, and
- 23:54comfort, dedicated pain management teams using
- 23:57multimodal analgesia, occupational therapists
- 23:59assisting with adaptations for daily living,
- 24:02or for geriatricians who are utterly vital for
- 24:04managing comorbidities. and optimizing the patient's
- 24:06overall medical health. Nutritionists and robust
- 24:09community rehabilitation support teams for ongoing
- 24:11recovery after discharge. It takes a village.
- 24:14It really does sound like a team effort. What
- 24:16are the key components? Key components include
- 24:18meticulous pain management. Getting that right
- 24:21is fundamental. Correcting any fluid and electrolyte
- 24:24imbalances. Proactive pressure area care to prevent
- 24:27devastating pressure sores. Early chest physiotherapy
- 24:30to prevent pneumonia and limb physiotherapy to
- 24:32maintain muscle strength and joint range. Early
- 24:35progression to sitting out of bed is crucial.
- 24:37And of course, venous thromboembolism or VTE
- 24:40prophylaxis blood thinners is critical throughout
- 24:43to prevent clots. But the cornerstone is early
- 24:46mobilization. Patients are actively encouraged
- 24:48to move as pain allows, often self -regulating
- 24:51their weight -bearing. We often find that elderly
- 24:54patients in particular frequently struggle with
- 24:56strict non -weight -bearing instructions due
- 24:58to other medical issues, perhaps upper limb weakness
- 25:01from arthritis or balance problems. So you adapt?
- 25:04We have to be pragmatic. Supervised ambulation
- 25:06with appropriate walking aids, like a Zimmer
- 25:09frame, is common and actively encouraged as soon
- 25:11as it's safe. All the while we maintain constant
- 25:14clinical and radiological surveillance, usually
- 25:16with weekly x -rays initially, to watch for any
- 25:19late displacement that might change the plan.
- 25:21And what about traction? Does that still have
- 25:23a role? The role of prolonged skeletal traction
- 25:25has diminished significantly in modern management,
- 25:28especially for frail elderly patients. It has
- 25:31major disadvantages. Pressure sores, muscle wasting,
- 25:35joint stiffness, risk of pin site infection,
- 25:38and the pins can easily disengage in porous osteoporotic
- 25:42bone. It might be used very short -term preoperatively,
- 25:45but not generally as a definitive long -term
- 25:48treatment anymore. What does the evidence say
- 25:51about outcomes for this non -operative approach?
- 25:54Well, perhaps surprisingly to some, studies have
- 25:56shown reasonably good functional outcomes in
- 25:58select elderly patients treated non -operatively,
- 26:01even for some fracture patterns that would typically
- 26:04meet operative criteria in younger, fitter individuals.
- 26:07What's truly interesting is that there's no convincing
- 26:09evidence when you adjust for comorbidities that
- 26:12conservative management inherently leads to higher
- 26:14mortality or higher re -operation rates compared
- 26:17to surgery in this specific elderly cohort. Yes,
- 26:21and secondary conversion rates to total hip arthroplasty,
- 26:24or THA, down the line are often quite similar
- 26:27for both conservatively and operatively treated
- 26:29patients in this age group. They might end up
- 26:32needing a hip replacement either way. Another
- 26:35fascinating point from a technical perspective
- 26:37is that performing a delayed primary arthroplasty,
- 26:40a planned hip replacement later on following
- 26:41a period of conservatively managed fracture healing,
- 26:44is often technically more straightforward than
- 26:46doing a secondary THA after a failed surgical
- 26:49fixation. This is primarily due to less scar
- 26:52tissue formation and no hardware interference
- 26:54from plates and screws that need removing. So
- 26:57this functional conservative approach really
- 26:59highlights a pragmatic, patient -centered philosophy
- 27:01when facing these complex challenges in our older
- 27:03population. That's a truly crucial distinction
- 27:06from perhaps older, more restrictive ideas of
- 27:08conservative care. Now, shifting gears for fractures
- 27:12that are significantly displaced, unstable, and
- 27:14deemed suitable for surgery, open reduction internal
- 27:17fixation, or ORFF, remains a primary approach.
- 27:21Professor, what are the core goals when you undertake
- 27:23ORFF? What surgical techniques are involved?
- 27:26And crucially, what persistent challenges do
- 27:28you still face, especially in older patients?
- 27:30When ORFS is the chosen path, our primary goals
- 27:33are threefold, and each is absolutely critical
- 27:36for the long -term survival and function of the
- 27:38patient's hip. First, we aim to meticulously
- 27:40restore a smooth, gliding hip surface. The joint
- 27:44needs to move without friction or catching to
- 27:46prevent premature wear and pain. Second, we strive
- 27:49to achieve an anatomical reduction. That means
- 27:51the bone fragments are pieced back together as
- 27:53perfectly as possible, with the goal being post
- 27:56-operative displacement ideally less than two
- 27:58millimeters on follow -up imaging. That Jordan
- 28:00study reported achieving this level of reduction
- 28:02in about 84 % of their surgically treated cases,
- 28:05which is good, but still leaves a significant
- 28:07minority with less than perfect reduction. The
- 28:11third goal is to provide robust, stable fixation
- 28:14with plates and screws. This is essential to
- 28:17hold the reduction while the bone heals, and
- 28:20importantly to try and prevent or delay the onset
- 28:23of post -traumatic osteoarthritis, which unfortunately
- 28:25remains a significant long -term complication
- 28:28even after technically successful surgery. Is
- 28:30there an ideal time to do the surgery? Yes. The
- 28:33optimal timing for ORFF is generally considered
- 28:35to be in the window between about 3 and 10 days
- 28:38post -injury. Why that specific window? Well,
- 28:41this allows some of the initial soft tissue swelling
- 28:43to subside, making the surgery technically easier
- 28:46and potentially reducing room complications.
- 28:49But it's before significant bone resorption or
- 28:51fibrous tissue formation occurs at the fracture
- 28:53site, which can make achieving an anatomical
- 28:56reduction much more difficult. The fragments
- 28:58sort of get sticky and resistant to moving back
- 29:01into place. Delays beyond 10 days can certainly
- 29:04complicate reductions significantly, and delays
- 29:07exceeding 3 weeks can lead to substantial problems
- 29:09with both achieving reduction and maintaining
- 29:11stable fixation due to that progressive bone
- 29:14resorption and early callus formation. How do
- 29:16you decide which surgical approach to use? The
- 29:19surgical approach is chosen very carefully, based
- 29:21almost entirely on the specific fracture pattern
- 29:24identified on the CT scan. You tailor the approach
- 29:27to get the best access to the fractured columns
- 29:29that need fixing. For anterior approaches, we
- 29:32commonly use either the classic ilioinguinal
- 29:34approach or, increasingly, the modified stoppa
- 29:38approach, sometimes combined with a lateral window.
- 29:40The modified STAPA in particular is highlighted
- 29:43for giving excellent visualization of the anterior
- 29:45column in the medial wall or quadrilateral plate,
- 29:49and it can even allow some access to the anterior
- 29:51aspect of the posterior column. It's particularly
- 29:54beneficial for buttressing comminuted medial
- 29:56wall fractures. And for posterior fractures?
- 29:59For posterior approaches, the workhorse is the
- 30:01Kocher -Langenbeck approach. This is commonly
- 30:04used for posterior wall and posterior column
- 30:06fractures. Occasionally for very complex patterns,
- 30:09like some both column fractures, a combination
- 30:11of approaches, perhaps anterior and posterior,
- 30:13might be necessary. But this significantly increases
- 30:16the operative time, blood loss, and overall morbidity
- 30:19for the patient. So we try to avoid it if possible.
- 30:21Can you walk us through the basic surgical technique?
- 30:24Sure. In terms of surgical techniques, the displaced
- 30:27bone fragments are first carefully repositioned,
- 30:29or reduced, back into their normal anatomical
- 30:32alignment, often using specialized clamps and
- 30:35instruments, all under fluoroscopic guidance
- 30:37live X -ray checks. Then metal plates contour
- 30:41to the bone shape and screws are meticulously
- 30:44attached to the outer surfaces of the bone to
- 30:46hold the fragments securely while the fracture
- 30:48heals. In osteoporotic bone, there's a growing
- 30:51use of locking implants plates, where the screws
- 30:54lock into the plate itself at a fixed angle.
- 30:57This theoretically provides better fixation stability
- 30:59in weak bone, though comprehensive comparative
- 31:02evidence showing superior outcomes versus conventional
- 31:04plates is still somewhat limited but emerging.
- 31:07What about bone grafting? Yes, that's often crucial.
- 31:10It's very important to consider bone grafting,
- 31:12using either autograft taken from the patient's
- 31:14own pelvis or perhaps cancerless bone substitutes
- 31:17to fill any underlying metaphysical defects,
- 31:20particularly after elevating impacted articular
- 31:23fragments. If you lift up a depressed piece of
- 31:26joint surface, there's often a void underneath.
- 31:29Filling this void is critical for supporting
- 31:32the elevated fragments and preventing them from
- 31:34collapsing again under load during weight bearing.
- 31:36Despite the best techniques, complications can
- 31:39still happen. Oh, absolutely. Despite meticulous
- 31:41technique, potential intraoperative and early
- 31:44post -operative complications are significant
- 31:46and must always be anticipated and discussed
- 31:49with the patient. Sciatic nerve injury is a major
- 31:51risk, particularly with the Cochlear -Langenbeck
- 31:54posterior approach. Reported rates are around
- 31:56210%, and the Jordan study reported a 3 .5 %
- 32:00rate of iatrogenic injury, meaning caused by
- 32:02the surgery itself. This can lead to the functionally
- 32:05debilitating foot drop. Heterotopic ossification,
- 32:08or HO, that abnormal growth of bone and the soft
- 32:11tissues around the hip is another significant
- 32:13concern. The highest incidence is seen with the
- 32:16older, more extensive approaches, though it seems
- 32:18to be lower with the ilioinguinal approach. We
- 32:21sometimes use prophylaxis, like radiation or
- 32:24medication, to try and prevent it in high -risk
- 32:26cases. There is also always a risk, albeit small,
- 32:30of damage to the blood supply of the femoral
- 32:32head during the surgery or from the initial injury,
- 32:34which could lead to that dreaded irascular necrosis
- 32:36later on. Looking at the longer term, what are
- 32:39the outcomes and challenges of ORIF? Well, looking
- 32:42at the outcomes and challenges. Whilst the clinical
- 32:45outcome strongly correlates with the quality
- 32:47of the articular reduction, the closer you get
- 32:49it to anatomical. Generally, the better the result.
- 32:52A really significant proportion of patients,
- 32:54maybe up to 30 % in some studies, and perhaps
- 32:57around 31 % overall in others, still go on to
- 33:00develop post -traumatic arthritis, even with
- 33:02a good -looking x -ray initially. So a good reduction
- 33:05doesn't guarantee success. Unfortunately, not
- 33:07always. And this frequently leads to a high rate
- 33:10of late conversion to total hip arthroplasty,
- 33:13or THA. Some studies suggest 20 -25 % of elderly
- 33:16patients might need a revision surgery or conversion
- 33:19to a hip replacement within the first one to
- 33:21two years after their initial ORF. We also know
- 33:25that the presence of that goal sign on the initial
- 33:27imaging indicating severe dome impaction is considered
- 33:31a very strong predictor of orioth failure in
- 33:33geriatric acetabular fractures. Seeing that often
- 33:36prompts serious consideration for an acute THA
- 33:39from the outset rather than attempting ORF. It's
- 33:43also important to note that while the operative
- 33:45treatment itself doesn't necessarily increase
- 33:47or decrease mortality when you carefully account
- 33:49for comorbidities, high one -year mortality rates
- 33:51up to 25 % in one study are reported in this
- 33:55elderly population undergoing surgery. This is
- 33:57often influenced by factors like age over 70
- 34:00and their overall medical frailty. often measured
- 34:02by things like the Charleston Comorbidity Index.
- 34:05It truly underscores the vital importance of
- 34:07comprehensive medical optimization before, during,
- 34:09and after any major surgery in these vulnerable
- 34:12patients. That's a truly comprehensive and frankly
- 34:15quite sobering look at the outcomes sometimes
- 34:18seen with traditional ORIF. Given these persistent
- 34:20challenges, particularly in patients with poor
- 34:23bone quality, you mentioned an alternative strategy
- 34:25has emerged, the fix and replace approach or
- 34:28acute total hip arthroplasty. Professor, could
- 34:31you explain this concept and its specific role?
- 34:33When might you choose this? Yes, the fix and
- 34:35replace strategy or acute THA combined with fixation
- 34:39represents a significant evolution in our thinking,
- 34:42particularly for managing these fractures in
- 34:44elderly or osteoporotic patients. The rationale
- 34:47is really to directly address those challenges
- 34:49we just discussed. The difficulty of achieving
- 34:52stable fixation in poor bone and the relatively
- 34:55high failure rates seen with ORIF alone in this
- 34:57group. At the same time, it aims to facilitate
- 35:00earlier weight bearing and functional recovery,
- 35:02which is so crucial for older patients to avoid
- 35:04deconditioning. So fixing and replacing in one
- 35:07go. Exactly. Instead of solely attempting to
- 35:10reconstruct the native joint, this approach combines
- 35:13fracture fixation stabilizing the columns with
- 35:16an immediate total hip arthroplasty during the
- 35:18same operation. There's some compelling data
- 35:21emerging. One study, for instance, highlighted
- 35:24its potential effectiveness, showing 100 % hip
- 35:27joint survival, meaning no further surgery needed
- 35:29on the hip replacement with this combined approach,
- 35:32compared to just about 29 % survival of the native
- 35:34hip after fixation alone in a comparable group.
- 35:37That's a stark difference. So when is it indicated?
- 35:40What are the triggers? Well, the indications
- 35:42for fix and replace are still evolving and there
- 35:44isn't universal consensus. But common factors
- 35:46that push us towards it include very complex
- 35:49judit laturnal fracture patterns, especially
- 35:51those involving both columns or significant combination
- 35:54of the weight bearing dome. The presence of significant
- 35:57pre -existing hip osteoarthritis is a strong
- 35:59indicator. Associated femoral head or neck fractures
- 36:03often make reconstruction impossible. Any pathological
- 36:06fracture through tumor. Significant cartilage
- 36:08damage seen either on imaging or at the time
- 36:11of surgery to either the femoral head or the
- 36:13incetabulum. And patient factors. Yes, poor bone
- 36:16quality, significant osteopenia or osteoporosis
- 36:18where you anticipate fixation will be unreliable
- 36:21is a major factor. Fractures deemed unreconstructable.
- 36:24patients presenting after a prolonged hip dislocation
- 36:27where the femoral head might be damaged, or delayed
- 36:30presentations where the window for optimal ORIF
- 36:32has closed. Furthermore, several negative prognostic
- 36:35factors we discussed earlier, like age over 40
- 36:37or certainly over 60, an anticipated poor reduction
- 36:40with more than three millimeters of residual
- 36:42displacement, multifragmentary fractures, very
- 36:46significant initial displacement of over 20 millimeters,
- 36:48or delayed surgery, particularly more than five
- 36:50days for associated patterns, or 15 days for
- 36:53elementary all might steer the decision towards
- 36:56this combined procedure. How is it done technically?
- 36:59Is it just like a standard hip replacement? Not
- 37:01quite. It's significantly more complex. The primary
- 37:05principle technically is still to achieve stable
- 37:07osteosynthesis, stable fixation of the acetabular
- 37:11columns first, typically using plates and screws.
- 37:14For example, we might meticulously use two posterior
- 37:17column plates to achieve optimal rotational stability
- 37:20of the hemipelvis. This creates a robust, bony
- 37:23foundation onto which the acetabular prosthetic
- 37:25component, the cup, can be securely implanted.
- 37:28So you fix the pelvis first, then put the cup
- 37:30in? Essentially. Yes, modern practice often involves
- 37:33using highly porous acetabular components like
- 37:36trabecular metal or similar materials, which
- 37:39offer excellent biological fixation potential.
- 37:41These cups often have multiple screw options,
- 37:44allowing fixation into intact bone away from
- 37:46the fracture lines. Sometimes these cups can
- 37:49even be drilled through in strategic locations
- 37:51to place additional screws, for instance, placing
- 37:54an anterior colon screw through the metal shell
- 37:56from a posterior approach to achieve a really
- 37:58strong triangular purchase that significantly
- 38:00enhances the fixation stability. That sounds
- 38:02technically demanding. What about the surgical
- 38:04approach? There's also been an evolution in surgical
- 38:07approaches for this. While older techniques might
- 38:09have involved complex constructs with intra -pelvic
- 38:12wires and bulky anti - protrusion cages, modern
- 38:16strategies often favor using a single posterior
- 38:18approach, like the Kocher -Langenbeck. This allows
- 38:21the surgeon to both fix the crucial posterior
- 38:24column and wall fragments and then implant the
- 38:27arthroplasty components through the same incision.
- 38:29This potentially avoids the extensive soft tissue
- 38:32disruption and increased complication risks associated
- 38:35with needing dual anterior and posterior approaches.
- 38:39We might also use the patient's own femoral head
- 38:41bone graft after it's removed for the arthroplasty
- 38:43to pack and support posterior wall defects, helping
- 38:46to reconstruct the bone stock behind the cup.
- 38:48It sounds effective, but complex. What about
- 38:51the downsides, the outcomes, and complications?
- 38:53You're right to ask. While fix and replace can
- 38:56be highly effective in preserving hip function
- 38:58and allowing early mobilization, it is undeniably
- 39:00a major surgical insult, particularly for frail
- 39:03elderly patients. It's a bigger operation than
- 39:06either ORIF or a standard primary hip replacement
- 39:09alone. It typically involves significantly longer
- 39:12operative times, averaging around three hours,
- 39:14174 minutes in one review, and substantially
- 39:17greater blood loss. averaging close to a liter,
- 39:20maybe 964 milliliters, compared to traditional
- 39:23ORIF. And complication rates. Reported complication
- 39:26rates are significant. They hover around 20 %
- 39:29in some meta -analyses, but individual studies
- 39:32report rates ranging up to nearly 60%. These
- 39:35include infections, which are always a major
- 39:37concern with implants and extensive surgery,
- 39:39heterotopic ossification, although some studies
- 39:41surprisingly suggest lower rates of clinically
- 39:44significant HO with acute THA compared to delayed
- 39:47THA after ORIF, and aseptic loosening of the
- 39:50acetabular component over time requiring revision
- 39:52surgery. The revision rate was about 2 .3 % in
- 39:55one systematic review over a medium -term follow
- 39:57-up of about 4 .5 years. Dislocation rates can
- 40:00also be higher than standard THA. What about
- 40:03mortality with this bigger operation? Mortality
- 40:06rates are also a serious consideration. The mean
- 40:08reported rate is around 9%, but studies have
- 40:11shown rates up to 58 % at three years in some
- 40:14very frail cohorts, with perhaps 26 % mortality
- 40:17in the first year alone being reported in one
- 40:20challenging group. It's crucial to acknowledge
- 40:22that the high -level evidence base for acute
- 40:25THA, specifically for acetabular fractures, is
- 40:28still developing. This means that the surgeon's
- 40:31experience, judgment, and the specific capabilities
- 40:33of the treating center remain absolutely crucial
- 40:35in guiding these complex high -stakes decisions.
- 40:38So it really requires a balanced perspective.
- 40:40While it may lead to better intermediate hip
- 40:42survival and function compared to Oriaf alone
- 40:45in selected elderly patients, the decision for
- 40:47fix and replace must be very carefully weighed
- 40:49against these significant upfront risks and the
- 40:51potential alternative of a simpler delayed THA
- 40:54after a period of functional conservative management,
- 40:56especially for the most committed difficult fractures
- 40:59in the frailest patients. That's a truly comprehensive
- 41:02and again quite a nuanced look at the fix and
- 41:05replace strategy and the critical decision making
- 41:08involved. In the immediate treatment strategy,
- 41:11Professor, what truly dictates a patient's long
- 41:13-term journey? What factors determine the ultimate
- 41:16survival of their native hip after an acetabular
- 41:19fracture? You use that phrase, death of the hip.
- 41:22What predicts that? This really gets to the heart
- 41:24of the long -term impact of these injuries. We
- 41:27use that concept of death of the hip essentially
- 41:29as the ultimate need for a total hip replacement,
- 41:32sometimes many years after the initial injury
- 41:34and fixation. Several key prognostic indicators
- 41:37truly dictate this long -term journey and determine
- 41:40if that native hip can be preserved or if it's
- 41:42destined for replacement. What's the most significant
- 41:44factor? The strongest predictor of poor outcos,
- 41:47unequivocally, is age. Older patients, especially
- 41:51those over 60, or perhaps even over 40, according
- 41:54to some research, are significantly more likely
- 41:57to have fragile osteoporotic bone, experience
- 42:00higher rates of surgical and medical complications,
- 42:02and ultimately have a greater chance of requiring
- 42:04a THA. Their physiological reserve is simply
- 42:08lower, making recovery more arduous, and achieving
- 42:11lasting stable fixation is inherently more difficult.
- 42:14And after age. Another paramount factor is the
- 42:17quality of the articular reduction achieved at
- 42:19the time of surgery, if surgery is performed.
- 42:21An imperfect reduction, clinically defined as
- 42:24post -operative displacement persisting at greater
- 42:26than 2 millimeters, significantly increases the
- 42:29risk of developing post -traumatic arthritis.
- 42:31If that smooth joint surface isn't perfectly
- 42:33realigned, even by a millimeter or two, it inevitably
- 42:37sets the stage for accelerated wear and tear,
- 42:39leading to progressive pain, stiffness, and joint
- 42:41destruction. Does the fracture pattern itself
- 42:43matter long term? Yes. Specific fracture patterns
- 42:46and their initial severity also play a major
- 42:49role. For example, Posterior wall fractures,
- 42:52despite sometimes appearing relatively simple
- 42:54on initial assessment, often carry a surprisingly
- 42:57poor long -term prognosis. This is often due
- 43:01to associated complications like subtle marginal
- 43:03impaction, higher risk of sciatic nerve injury,
- 43:06heterotopic ossification, and a propensity for
- 43:09secondary osteoarthritis development. Similarly,
- 43:12the more complex patterns like transverse and
- 43:14T -type fractures and the associated both -column
- 43:16fractures often present higher risks just given
- 43:19their inherent instability and the sheer extent
- 43:21of disruption to the joint architecture. What
- 43:23about damage to other structures? Absolutely.
- 43:26Associated injuries are critical prognostic indicators.
- 43:29This includes any direct damage to the femoral
- 43:31head cartilage itself sustained during the initial
- 43:34injury or dislocation, significant marginal impaction,
- 43:38That crushing of the cancellous bone under the
- 43:40articular surface, especially in the weight -bearing
- 43:42dome, is a bad sign. Any pre -existing arthritis
- 43:46in the hip joint obviously worsens the prognosis.
- 43:49And other major systemic injuries, like head
- 43:51or chest trauma, can significantly complicate
- 43:54the overall recovery trajectory and impact the
- 43:56functional outcome. And that seagull sign we
- 43:59discussed earlier, visible on imaging and indicative
- 44:01of severe dome impaction, is a particularly strong
- 44:04poor prognostic sign. Seeing that often immediately
- 44:08suggests that attempting to save the native joint
- 44:10with ORIVE is likely futile, and total hip replacement,
- 44:13either acutely or delayed, might be the more
- 44:15realistic option. Does delaying surgery affect
- 44:17the long -term outcome? Yes. The delay to surgery
- 44:20significantly impacts outcomes, particularly
- 44:23for ORIF. Prolonged delays beyond that optimal
- 44:26window say more than five days for complex associated
- 44:30fractures or perhaps more than 15 days for elementary
- 44:32fractures have been consistently shown to negatively
- 44:35impact a surgeon's ability to achieve and maintain
- 44:37an anatomical reduction. This directly affects
- 44:40the long -term prognosis and increases the risk
- 44:42of secondary osteoarthritis developing later.
- 44:44What are the most common long -term problems
- 44:46people face? In terms of common long -term complications,
- 44:50post -traumatic arthritis is by far the most
- 44:52frequent issue, leading to chronic pain, stiffness,
- 44:55and functional limitation, often necessitating
- 44:57that late THA. Heterotopic ossification is also
- 45:01common, where that abnormal bone grows around
- 45:03the joint, physically restricting movement. A
- 45:06vascular necrosis, or AVN, of the femoral head
- 45:09occurs in roughly 6 to 7 percent of all acetabular
- 45:12fractures, but the risk is higher. perhaps up
- 45:14to 18 % in posterior fracture patterns or after
- 45:17dislocation, where the blood supply to the femoral
- 45:19head is most vulnerable. Other significant long
- 45:22-term issues include chronic pain, which can
- 45:24be multifactorial, and persistent nerve injury,
- 45:27such as that debilitating foot drop from sciatic
- 45:29nerve damage, which can require long -term bracing
- 45:31and significantly impact quality of life. How
- 45:34long does recovery typically take? The recovery
- 45:36timeline for these major injuries is extensive
- 45:38and requires considerable patience from both
- 45:40the patient and the clinical team. While it typically
- 45:43takes around 9 -12 months for the acetabular
- 45:46fracture itself to completely heal radiologically,
- 45:50achieving the full restoration of mobility and
- 45:51function generally occurs somewhere within the
- 45:546 -12 month window, post -injury, sometimes longer.
- 45:58It's really important to set realistic expectations
- 46:01for patients from the outset. Due to the complex
- 46:03nature of these injuries and the potential for
- 46:05these long -term complications, many patients,
- 46:08particularly those with more severe initial injuries
- 46:11or those who develop complications, may not fully
- 46:14return to their pre -injury activity levels or
- 46:16occupations. The ultimate goal then is always
- 46:18to maximize their functional outcome and quality
- 46:21of life within the limitations imposed by the
- 46:23injury itself. So summing that up. Yes. In conclusion,
- 46:27Whilst complications can certainly be anticipated
- 46:29with these severe injuries, timely intervention,
- 46:33meticulous surgical technique when indicated,
- 46:35and truly comprehensive post -operative care,
- 46:38including rigorous DVT prophylaxis, early but
- 46:41safe mobilization protocols, and vigilant pain
- 46:44management are absolutely crucial for mitigating
- 46:47adverse outcomes and improving the long -term
- 46:49prognosis. It's all about aiming for the best
- 46:52possible quality of life we can achieve for every
- 46:54individual patient facing this challenge. injury.
- 46:57Professor, that was an incredibly thorough and
- 46:59insightful review. You've distilled years of
- 47:02complex experience into truly digestible knowledge
- 47:05for us. Let's move into a quick lightning round
- 47:07now just to crystallize some key insights for
- 47:09our listeners. First up, one essential piece
- 47:12of imaging you simply cannot go without for accurate
- 47:15acetabular fracture assessment. Oh, definitely
- 47:18a high quality CT scan with meticulous multi
- 47:20-planar reconstructions. It's non -negotiable
- 47:22for planning. For managing our older patients
- 47:25with these fractures, what's a single core principle
- 47:27that really underpins your entire approach? I'd
- 47:29say proactive, multidisciplinary medical optimization
- 47:32combined with a tailored focus on early functional
- 47:35mobilization. Get them assessed, get them optimized,
- 47:38get them moving safely. What's one common diagnostic
- 47:40or management pitfall that orthopedic professionals
- 47:43should always be wary of with these intricate
- 47:45injuries? A common pitfall. perhaps failing to
- 47:49thoroughly assess for and address marginal impaction
- 47:52of the articular surface, or, relatedly, misinterpreting
- 47:56complex pelvic ring injuries that involve the
- 47:59acetabulum as solely acetabular fractures. Understanding
- 48:02the full extent of pelvic instability is key.
- 48:04Finally, what's one quick win if such a thing
- 48:07exists for significantly reducing long -term
- 48:09complications after an acetabular fracture? A
- 48:12quick win? Well, it's not always quick or easy,
- 48:14but achieving and rigorously maintaining an anatomical
- 48:17articular reduction and keeping that post -operative
- 48:20displacement under two millimeters is undoubtedly
- 48:22the cornerstone of preventing or delaying post
- 48:25-traumatic arthritis. That's the goal. This deep
- 48:28dive has truly illuminated the intricate world
- 48:30of acetabular fractures, offering critical insights
- 48:33for our medical professional audience. Let's
- 48:35just quickly recap some key takeaways to enhance
- 48:37your understanding and clinical practice. Firstly,
- 48:40a crucial understanding. Acetabular fractures
- 48:43are distinct, complex intraarticular injuries.
- 48:46Remember, even seemingly simple patterns like
- 48:49posterior wall fractures, often linked to dashboard
- 48:51injuries, can carry a surprisingly poor long
- 48:54-term prognosis due to associated issues like
- 48:57impaction or nerve injury. Precise early diagnosis
- 49:00is vital. Secondly, accurate diagnosis hinges
- 49:02not just on standard x -rays, but specifically
- 49:05on judit views and critically detailed CT scans.
- 49:08These advanced images reveal subtle yet vital
- 49:10signs like the GUL sign or SPUR sign, which can
- 49:13entirely alter your treatment approach and the
- 49:15patient's prognosis. Thirdly, remember management
- 49:18is highly individualized. It spans from meticulous
- 49:21functional conservative care, emphasizing early
- 49:23mobilization, especially in the frail elderly,
- 49:25to comp surgery like RAF or acute THA. The choice
- 49:28depends heavily on the patient's health, bone
- 49:31quality, fracture pattern, and importantly, available
- 49:34surgical expertise. Fourthly, the long -term
- 49:38outlook and the ultimate survival of the native
- 49:40hip hinge significantly on factors like age,
- 49:42initial injury severity, and pattern, but most
- 49:45critically, the quality of articular reduction
- 49:47achieved. Diligent prevention and management
- 49:50of long -term complications like arthritis, HO,
- 49:53and AVN are paramount. And finally, never forget,
- 49:57an associated hip dislocation is a true surgical
- 50:00emergency. It demands urgent reduction, ideally
- 50:03within hours, to mitigate both immediate risks
- 50:05like AVN and long -term consequences for the
- 50:08patient. Our deep dive into acetabular fractures
