- 0:00Welcome to The Deep Dive, the show where we cut
- 0:02through the noise, unpack complex medical topics,
- 0:05and pull out the crucial insights that can genuinely
- 0:07elevate your clinical practice. Today, we're
- 0:10plunging into a subject that, well, at first
- 0:11glance, seems incredibly straightforward, yet
- 0:14it consistently throws up significant challenges
- 0:16in diagnosis, treatment, and especially long
- 0:19-term patient recovery, ankle sprains. Now, when
- 0:22we talk about how common these are, the figures
- 0:24are really quite startling. We're looking at
- 0:27an estimated 28 ,000 ankle sprains happening
- 0:30every single day in the United States alone.
- 0:35It really is. And if you've spent any time in
- 0:37sports medicine or even A &E, you'll know it's
- 0:40often the single biggest reason why athletes
- 0:42miss participation. So despite their ubiquity,
- 0:45their impact, both on individuals and on health
- 0:47care systems, is undeniably profound. Our mission
- 0:51today is to unpack the intricate nuances of these
- 0:54injuries, from the fundamental anatomy that underpins
- 0:56them to the cutting edge advanced treatment protocols
- 0:59and, crucially, the prevention strategies that
- 1:02can make all the difference. We want to provide
- 1:05you, our discerning medical professional listener,
- 1:08with a comprehensive yet concise understanding
- 1:10that you can apply directly. And to guide us
- 1:13through this intricate landscape, I'm absolutely
- 1:15thrilled to welcome Prof. Mal Imam. Thank you
- 1:18so much for having me. It's a genuine pleasure.
- 1:20You've really nailed the core issue right there.
- 1:22Ankle sprains are indeed incredibly common, almost
- 1:24a rite of passage for many active individuals,
- 1:26aren't they? Almost seems that way sometimes.
- 1:28But the critical point... And one that's so often
- 1:30underestimated is their potential for serious
- 1:33debilitating long -term complications if they're
- 1:36not managed appropriately from day one. We frequently
- 1:40see patients in clinic years down the line still
- 1:42grappling with persistent pain, instability,
- 1:45or even early arthritis, all stemming from an
- 1:48initial sprain that simply wasn't given the attention
- 1:50it deserved. So that initial management is key.
- 1:53Absolutely critical. For this deep dive, we're
- 1:55going to embark on a comprehensive journey, starting
- 1:58with the very first moment of injury, understanding
- 2:00the mechanisms, then moving through precise diagnostic
- 2:03approaches, exploring the full spectrum of treatment
- 2:05from conservative to operative, and finally,
- 2:08really honing in on robust prevention strategies.
- 2:11Our shared aim is to arm you with actionable,
- 2:14evidence -based insights that can significantly
- 2:16improve patient outcomes. Right then. Let's roll
- 2:19up our sleeves and get into it. Before we even
- 2:21begin to unpick the various types of ankle injuries
- 2:24and their manifestations, could you perhaps take
- 2:27us back to basics? For many of us, it's, well,
- 2:30it's been a while since anatomy lab. Could you
- 2:32refresh our memory on the critical structural
- 2:35foundations of the ankle? Specifically, which
- 2:38ligaments are the prime suspects, the most vulnerable
- 2:41players in a typical ankle sprain scenario? Absolutely.
- 2:45Happy to. It's always vital to start with the
- 2:47foundations, as understanding the anatomy illuminates
- 2:49the pathology. The ankle joint itself is a marvel
- 2:53of engineering, really. A complex articulation
- 2:56involving three primary bones, the tibia and
- 2:59fibula, which are the long bones of your lower
- 3:01leg, and the talus, the crucial bone in your
- 3:03foot, that essentially acts as the fulcrum between
- 3:06your leg and the rest of your foot. The connecting
- 3:07piece. Precisely. These three bones are held
- 3:11together quite ingeniously by a sophisticated
- 3:14network of robust ligaments. These aren't just
- 3:17passive restraints. They provide both the necessary
- 3:19static stability and also guide the intricate
- 3:22range of motion required for everything from
- 3:24a gentle stroll to a full -on sprint. When we
- 3:28talk about ankle sprains, we're almost exclusively
- 3:30referring to injuries to these ligaments. And
- 3:33we can broadly categorize them into two main
- 3:35groups based on their location and the type of
- 3:37force they resist. On the outer side of the ankle,
- 3:40the lateral aspect, we find the ligaments that
- 3:42are unfortunately the most frequent victims in
- 3:45ankle sprains. The absolute lead character here,
- 3:48if you will, but one that gets injured most commonly,
- 3:51is the anterior telofibular ligament, or ATFL.
- 3:54ATFL, okay. This ligament is quite slender and
- 3:56is positioned anteriorly at the front, connecting
- 3:58the fibula to the talus. It's typically injured
- 4:01when the foot is in a planter flexed or pointed
- 4:03down position and then rolls inwards that classic
- 4:06inversion mechanism like stepping awkwardly off
- 4:08a curb or landing badly from a jump. The classic
- 4:11going over on your ankle. Exactly that. It's
- 4:14the weakest of the lateral ligaments, which is
- 4:16why it bears the brunt of most inversion injuries.
- 4:20Following the ATFL in terms of injury frequency
- 4:22is the calcaneofibular ligament. or CFL. This
- 4:26one sits a bit deeper and more vertically, connecting
- 4:28the fibula to the calcaneus, your heel bone.
- 4:31So fibula to heel bone? Correct. It tends to
- 4:34be affected when the foot is in a more neutral
- 4:36or even dorsiflex, flexed upwards position, during
- 4:39an inversion injury. A critical distinction with
- 4:42the CFL is its role not just in ankle joint stability,
- 4:46but also in supporting the subtailer joint, which
- 4:48allows for inversion and eversion of the foot.
- 4:51Ah, so it affects more than just the main ankle
- 4:52hinge. Indeed. An injury to the CFL can have
- 4:56broader implications for foot mechanics. And
- 4:58then, less commonly involved, usually only in
- 5:01quite severe or multi -ligamentous injuries,
- 5:03is the posterior televibular ligament, or PTFL,
- 5:06which, as its name suggests, is at the back.
- 5:09Now, shifting our focus to the inner side of
- 5:11the ankle, the medial aspect, we encounter the
- 5:13exceptionally strong deltoid latiment. The medial
- 5:15side, right? Yes. This isn't a single band, but
- 5:19rather a broad, fan -shaped complex made up of
- 5:22several distinct parts. It provides truly substantial
- 5:26support to the inner ankle and plays a crucial
- 5:28role in limiting talar abduction. It's the outward
- 5:31movement of the talus. Okay. And its deep portion
- 5:34is particularly good at limiting external rotation
- 5:37of the talus. Essentially, it's the primary guardian
- 5:40against excessive aversion of the foot, where
- 5:43the ankle rolls outwards. So it stops the ankle
- 5:46collapsing inwards effectively. Precisely. It
- 5:48resists that outward roll, the aversion. Interestingly,
- 5:52because of its inherent strength and broad attachment,
- 5:55isolated injuries to the deltoid ligament are
- 5:57relatively rare. You don't see them often on
- 5:59their own. Not usually. When they do occur, they
- 6:02often signify a higher energy trauma or occur
- 6:04in conjunction with other injuries, sometimes
- 6:06even a fracture, because the bone gives way before
- 6:08the ligament does. Right, the forces must be
- 6:10significant. They usually are. So understanding
- 6:13these specific anatomical relationships, knowing
- 6:16exactly which ligament sits where and how it
- 6:19functions to provide stability is absolutely
- 6:22paramount. It's what allows us to accurately
- 6:24diagnose the mechanism of injury when a patient
- 6:26walks into our clinic. That's a truly excellent
- 6:29anatomical breakdown, Prof. It really paints
- 6:31a clear picture and sets the stage for understanding
- 6:33the injury itself. So with that intricate anatomy
- 6:35now firmly in our minds, let's move on to the
- 6:38practical reality. What are the primary types
- 6:41of ankle sprains we commonly encounter in clinical
- 6:43practice, and how do their underlying mechanisms
- 6:46and defining characteristics truly differ? I
- 6:48mean, it's not just a twisted ankle, is it? Precisely.
- 6:52It's far more nuanced than just a twisted ankle.
- 6:55For clinicians, classifying these injuries is
- 6:58fundamental to effective management. We primarily
- 7:01categorize ankle sprains based on the direction
- 7:03the foot moves during the injury, which in turn
- 7:05dictates which ligaments bear the brunt of the
- 7:07force. There are essentially three main types
- 7:10we encounter. First, and by far the most ubiquitous,
- 7:13are inversion sprains. These are what many colloquially
- 7:16refer to as low ankle sprains, and they represent
- 7:18over 90 % of all ankle sprains we see. Over 90
- 7:21%? Easily. The mechanism is exactly as it sounds.
- 7:25The foot rolls inward, often quite violently,
- 7:28leading to damage of those lateral ligaments
- 7:29we just discussed, predominantly the ATFL and
- 7:32frequently the CFL as well, especially if the
- 7:34injury is more severe. So the outer ligaments?
- 7:37Yes, the classic scenario is an inversion injury
- 7:41on a plantar flexed foot. Think of stepping into
- 7:44a pothole, landing awkwardly after a jump in
- 7:47netball, or simply misjudging a step off a curb.
- 7:50The forces here can be quite significant, often
- 7:53leading to immediate pain and swelling on the
- 7:55outer side of the ankle. Secondly, we have aversion
- 7:59sprains. These are significantly less common,
- 8:02and for good reason. As we just highlighted,
- 8:05the deltoid ligament on the inner side of the
- 8:07ankle is exceptionally robust. A big fan -shaped
- 8:09one. Exactly. An aversion sprain occurs when
- 8:11the ankle rolls outward, placing immense stress
- 8:13on this formidable deltoid ligament. These types
- 8:16of sprains typically demand a much more forceful
- 8:19external rotation or abduction mechanism, often
- 8:22involving a higher energy impact, such as a contact
- 8:24sports injury or a motor vehicle accident. Because
- 8:27the deltoid is so strong, an isolated aversion
- 8:30sprain is rare. You're often looking for an associated
- 8:32fracture, perhaps of the fibula, because the
- 8:35bone might break before the ligament pair. Interesting.
- 8:37And thirdly, a less common but often far more
- 8:40debilitating and challenging type are syndesmotic
- 8:42sprains, universally known as high ankle sprains.
- 8:46The dreaded high ankle sprain. Indeed. While
- 8:49they only account for about 1 % to 10 % of all
- 8:52ankle sprains, their significance is disproportionately
- 8:56high. These injuries involve the tibiofibular
- 8:59ligaments, specifically the anterior and posterior
- 9:02tibiofibular ligaments, and the interosseous
- 9:05membrane, which connect the tibia and fibula
- 9:07bones above the actual ankle joint. Right, higher
- 9:09up the leg. Correct. They're critical for maintaining
- 9:12the integrity of the tibiofibular syndesmosis,
- 9:14which forms the roof of the ankle mortis. These
- 9:17sprains are frequently associated with high -end
- 9:19impact activities and powerful twisting motions,
- 9:22particularly where there's external rotation
- 9:23of the foot on a fixed or planted leg or hyperdorsiflexion.
- 9:27Like in rugby or football tackles. Exactly those
- 9:30sorts of scenarios. Think of a rugby player getting
- 9:33tackled with their foot caught or a footballer
- 9:35twisting on the pitch. The key takeaway here
- 9:38is that syndesmotic injuries can lead to significant
- 9:41and chronic instability if not correctly identified
- 9:44and managed, and they invariably demand a much,
- 9:47much longer recovery period compared to the more
- 9:50common lateral sprains. Much longer recovery,
- 9:52okay. Significantly longer. Yeah. Beyond this
- 9:55specific mechanism, we then classify ankle sprains
- 9:58by their severity, which naturally directly dictates
- 10:01the immediate management plan and the prognostic
- 10:04outlook. This uses a widely accepted three -grade
- 10:07system, and it's essential for clinical decision
- 10:10-making. Great ice brains represent the mildest
- 10:12form. Here, there's just a slight stretching
- 10:15of the ligament fibers, perhaps with some microscopic
- 10:17tears. Clinically, you'll observe minimal pain,
- 10:20often a bit of mild swelling, and perhaps very
- 10:22slight localized ecomosis or bruising. So, quite
- 10:25subtle sometimes. Can be. Crucially, the patient
- 10:28can usually bear weight normally. albeit perhaps
- 10:31with some discomfort, and there's no detectable
- 10:34ligamentous instability during your physical
- 10:36examination. They might feel a bit stiff, but
- 10:39the joint itself feels solid. Grade 2 sprains
- 10:42indicate a more significant injury, a partial
- 10:45tearing of the ligament. At this grade, the pain
- 10:48is moderate, and you'll typically see more noticeable
- 10:50swelling and bruising. Patients will experience
- 10:53mild to moderate pain with weight bearing, and
- 10:55during your examination, you might detect slight,
- 10:58but definite instability. A bit wobbly. A bit
- 11:01wobbly, yes. A classic, though not universal,
- 11:04presentation for grade 2 sprains is often characteristic
- 11:06horseshoe -shaped bruise that appears around
- 11:08the heel. Ah, yes, I've seen that. Sort of wraps
- 11:10around the malleolus. Exactly. That pattern is
- 11:13quite indicative of the extent of the soft tissue
- 11:15damage and the underlying hematoma. Finally,
- 11:19grade 3 sprains represent the most severe injury,
- 11:22a complete rupture of one or more ligaments.
- 11:25These are truly painful injuries, presenting
- 11:27with pronounced, often excruciating, pain, significant
- 11:31and rapid swelling, extensive ecomosis that can
- 11:34spread quite widely, and sometimes even a visible
- 11:36deformity of the ankle due to the swelling and
- 11:38instability. Can't bear weight at all, usually.
- 11:41Often impossible or severely painful. And during
- 11:44your examination, you will detect substantial
- 11:46instability of the joint. It's this grade in
- 11:49particular where meticulous and careful management
- 11:51is absolutely critical to prevent the transition
- 11:54to long -term chronic instability and other complications
- 11:57we'll discuss later. Makes sense. Understanding
- 11:59these grades is truly fundamental for any clinician
- 12:02as it directly guides your immediate therapeutic
- 12:04approach and helps in setting realistic expectations
- 12:07for the patient's recovery trajectory. That distinction
- 12:10between the specific mechanisms and then the
- 12:12subsequent severity grading is incredibly helpful
- 12:15for navigating what patients present with. It
- 12:18transforms a vague twisted ankle into a precise
- 12:21diagnosis. Now, let's pivot and consider the
- 12:24why behind these injuries. What are the typical
- 12:27scenarios that often lead to ankle sprains, and
- 12:29what should we as clinicians be acutely aware
- 12:32of regarding both intrinsic patient -related
- 12:34factors and extrinsic environmental risk factors?
- 12:37What makes someone more vulnerable? It's a fantastic
- 12:40question because understanding the etiology is
- 12:43paramount, not just for acute management, but
- 12:45crucially for prevention. The primary cause of
- 12:48an ankle sprain is almost always a sudden, uncontrolled,
- 12:51and forceful twisting motion of the foot or ankle.
- 12:53Right. This can manifest in a myriad of common
- 12:56scenarios. Think of simply misstepping on uneven
- 12:59terrain, that unexpected dip in a pavement, or
- 13:01a rogue tree root on a trail run. Tripping or
- 13:04falling is another ubiquitous cause, where the
- 13:06foot can unexpectedly roll inward or outward
- 13:08upon impact, or as you lose balance. Happens
- 13:10to everyone. It really does. However, a very
- 13:14significant proportion of ankle sprains especially
- 13:16the more severe ones, occur during sports and
- 13:19high impact activities. Any sport that demands
- 13:22sudden directional changes, rapid pivoting, quick
- 13:25cuts, or repetitive jumping, is inherently high
- 13:28risk. We're talking about basketball, volleyball,
- 13:31tennis, football, rugby, netball, essentially
- 13:34any dynamic sport where the foot can get caught
- 13:36or twisted while the body continues its motion.
- 13:39Landing awkwardly from a jump, perhaps? Very
- 13:41common mechanism. In the more severe cases of
- 13:43ligament tearing, patients will often vividly
- 13:45report hearing or feeling a distinct pop or snap
- 13:48at the very moment of injury. Ah, the pop always
- 13:51makes your ears prick up. It certainly should.
- 13:54This auditory sensory feedback is a strong indicator
- 13:57of a significant ligamentous event, often a complete
- 13:59rupture, and should immediately raise your index
- 14:02of suspicion during history taking. Beyond these
- 14:05direct causes, we also identify a number of key
- 14:07risk factors that predispose individuals to ankle
- 14:09sprains or to recurrent sprains. These are broadly
- 14:12categorized into patient -related or intrinsic
- 14:14factors and environmental -related or extrinsic
- 14:17factors. Okay, intrinsic first. Yes. On the intrinsic
- 14:20side, we frequently observe individuals with
- 14:22preexisting biomechanical limitations. For example,
- 14:26limited dorsiflexion. That's a restricted upward
- 14:28movement of the foot towards the shin. Skiffness
- 14:31going upwards. Exactly. It significantly increases
- 14:34risk because it limits the anchor's ability to
- 14:37absorb shock and adapt to uneven surfaces. Similarly,
- 14:42decreased proprioception. The body's subconscious
- 14:45awareness of its position in space and a general
- 14:48balance deficiency are major contributors. So
- 14:50poor balance control. Precisely. If your body
- 14:54isn't getting accurate feedback on where your
- 14:56foot is in relation to the ground, or if your
- 14:58reflexive muscle responses are slow, you're far
- 15:01more likely to roll your ankle. Furthermore,
- 15:04a subtle cavivarous foot alignment, a foot structure
- 15:07characterized by a high arch and a heel that
- 15:09turns slightly inward. High arch is heel turned
- 15:12in. Yes. That can place the ankle in a persistently
- 15:14more vulnerable position for recurrent inversion
- 15:17injuries. This is a structural predisposition
- 15:19that puts the lateral ligaments under greater
- 15:21baseline tension. Making them more prone to injury.
- 15:24Inherently more prone. As for the extrinsic factors,
- 15:27Indoor court sports have historically presented
- 15:30the highest risk, primarily due to the combination
- 15:32of rapid multi -directional movements on often
- 15:35hard, unforgiving surfaces that offer high friction,
- 15:39sometimes causing the foot to stick while the
- 15:40body rotates. Like basketball or netball court.
- 15:43Exactly. Recognizing these modifiable risk factors
- 15:47is absolutely paramount. It's not just about
- 15:50treating the acute injury, it's about implementing
- 15:52effective long -term prevention strategies, particularly
- 15:55within athletic populations, to break that cycle
- 15:58of recurrent sprains. It's fascinating how those
- 16:01subtle biomechanical environmental factors can
- 16:03contribute to such a common injury. Now, when
- 16:06a patient actually walks into our clinic with
- 16:08a suspected ankle sprain, often in quite a bit
- 16:10of pain and distress, what are the absolute key
- 16:13symptoms we should be looking out for? And crucially,
- 16:16what are the essential elements of our clinical
- 16:18and imaging evaluations to ensure we arrive at
- 16:20an accurate diagnosis and, perhaps even more
- 16:23importantly, rule out anything more sinister,
- 16:25like a fracture or a more complex injury? This
- 16:28is truly where our clinical judgment shines,
- 16:30isn't it? When a patient presents, the symptoms
- 16:32they report will naturally guide your initial
- 16:34assessment. The most prevalent symptoms include
- 16:37acute pain, which can range from a dull ache
- 16:40to a sharp incapacitating pain, present at rest,
- 16:44exacerbated with weight -bearing, or during any
- 16:47movement of the ankle. Pain is obviously number
- 16:49one. Almost always. You'll almost invariably
- 16:52observe varying degrees of swelling and ecomosis
- 16:54or bruising around the affected area. This can
- 16:57be anything from mild puffiness to extensive
- 17:00disfiguring bruising that spreads widely across
- 17:03the foot and ankle. A very strong diagnostic
- 17:06indicator is tenderness to touch, specifically
- 17:09localized over the involved ligaments. This pinpoint
- 17:12tenderness directly over the ATFL or CFL, for
- 17:14example, is highly suggestive of their involvement.
- 17:17Finding that exact spot. Yes, it's very helpful.
- 17:20Patients will often describe a feeling of ankle
- 17:22instability or a sensation of the ankle giving
- 17:24way, particularly during movement or weight -bearing
- 17:26activities, even if it's a subtle feeling. Restricted
- 17:30range of motion is also extremely common due
- 17:31to pain, swelling, and muscle guarding. They
- 17:34just don't want to move it. Understandably. Less
- 17:37commonly, but important to note, some individuals
- 17:40might report numbness or tingling sensations
- 17:42in the foot or ankle, which warns consideration
- 17:45of nerve involvement. Great flag there. Potentially,
- 17:47yes. Needs careful assessment. And for those
- 17:51with recurrence sprains, they might describe
- 17:53new or persistent catching or popping sensations,
- 17:56which can signal associated intraarticular pathology,
- 17:59perhaps a loose body or cartilage damage. Now,
- 18:03Moving on to the clinical evaluation itself.
- 18:05It begins, as always, with a meticulous history.
- 18:09Understanding the precise mechanism of injury
- 18:11is crucial, how exactly the foot twisted, the
- 18:13direction of force, the surface, any immediate
- 18:16sounds or sensations like that pop we discussed.
- 18:18Getting the story straight. Absolutely. This
- 18:20immediately helps you narrow down which ligaments
- 18:22might be affected and the potential severity.
- 18:25The physical examination, while potentially painful
- 18:27for the patient due to acute inflammation and
- 18:29swelling, is absolutely essential. First, Observation.
- 18:34Visually assess the injured ankle. Crucially
- 18:36compare it to the contralateral uninjured ankle.
- 18:38Always compare. Always. Look for the extent of
- 18:41swelling. The exact location and pattern of ecumosis.
- 18:44Is it the classic horseshoe bruise? Is it more
- 18:46diffuse? Then palpation. Gently but systematically
- 18:51palpate around the entire ankle. Pinpointing
- 18:54tenderness directly over specific injured ligaments
- 18:57like the ATFL just anterior to the lateral malleolus
- 19:00or the CFL inferior to it is a key diagnostic
- 19:03step. You're also palpating around the malleoli
- 19:06and the base of the fifth metatarsal and navicular
- 19:08bone to rule out bony tenderness. Checking those
- 19:11Ottawa rules points. Exactly. We'll come back
- 19:13to those. Next, range of motion testing. Gently
- 19:16assess both active and passive movement of the
- 19:18ankle in all planes. While this will often be
- 19:21limited by pain and swelling in the acute phase,
- 19:23it gives you a baseline for functional impairment.
- 19:26Next, range of motion testing. Finally, and critically,
- 19:29stability testing helps assess the integrity
- 19:31of the ligaments. The interior drawer test is
- 19:33performed to check for excessive anterior displacement
- 19:36of the talus relative to the tibia. It's often
- 19:38best tested with the foot in slight plantar flexion
- 19:41when assessing the ATFL and endorsiflexion for
- 19:43the CFL. Testing that forward glide. Correct.
- 19:47However, its usefulness can be somewhat limited
- 19:49in the acute setting due to patient pain and
- 19:51muscle guarding. The TALR tilt test evaluates
- 19:54excessive ankle inversion typically. A difference
- 19:57greater than 15 degrees compared to the uninjured
- 19:59side is considered significant. 15 degrees difference.
- 20:02Yes, that's the threshold often cited. It strongly
- 20:05indicates injury to both the ATFL and CFL. This
- 20:08test is particularly valuable for diagnosing
- 20:10CFL injury by directly assessing overall ankle
- 20:13instability in the coronal plane. Now, regarding
- 20:16imaging studies, radiographs or x -rays are almost
- 20:20always your first -line imaging modality. Their
- 20:23primary purpose is to rule out fractures, which
- 20:25can often present with symptoms very similar
- 20:27to severe sprains. Crucial first step. Absolutely.
- 20:31The indications for x -rays are brilliantly guided
- 20:33by the widely adopted Ottawa ankle rules. These
- 20:36rules are incredibly sensitive, boasting a sensitivity
- 20:39between 96 % and 99 % for ruling out clinically
- 20:42significant ankle fractures. Very sensitive indeed.
- 20:45meaning if the patient doesn't meet the criteria,
- 20:47you can generally confidently exclude a fracture
- 20:50without x -rays, thereby reducing unnecessary
- 20:52radiation exposure. You should order x -rays
- 20:55if the patient presents with an inability to
- 20:57bear weight both immediately after the injury
- 20:59and in the emergency department or clinic, or
- 21:02if there's point tenderness over the posterior
- 21:03edge or tip of either the medial or lateral malleolus,
- 21:07or tenderness of the base of the fifth metatarsal
- 21:09or the navicular bone. So weight -bearing ability
- 21:12and those specific bony points. Those are the
- 21:14key criteria. Standard views include AP, lateral,
- 21:18and mortis views, with weight -bearing views
- 21:20where possible to assess joint space integrity
- 21:22under load. For suspected high ankle sprains,
- 21:25stress x -rays can be particularly useful for
- 21:28diagnosing syndesmosis injury. Stress views for
- 21:30the high sprains. Yes. You're specifically looking
- 21:33for asymmetric widening of the mortis, specifically
- 21:36a medial clear space widening greater than 4
- 21:39millimeters, and a tibiofibular clear space widening
- 21:42of 6 millimeters or more. These measurements
- 21:45indicate a diastasis, or separation, of the tibia
- 21:48and fibula. Varus stress fuse can also be used
- 21:51to diagnose CFL injury by assessing for an increased
- 21:54talar tilt. MRI is generally not routinely needed
- 21:58for the initial diagnosis of a straightforward
- 21:59ankle sprain. However, you should definitely
- 22:02consider an MRI if pain and instability persist
- 22:05for six to eight weeks following the initial
- 22:07sprain, despite appropriate conservative management.
- 22:09If things aren't getting better. Exactly. Or
- 22:11if you strongly suspect associated injuries that
- 22:14plain x -rays can't visualize. It's an excellent
- 22:17modality for evaluating soft tissue structures
- 22:19like perineal tendon pathology problems with
- 22:21the tendons on the outer ankle, osteochondral
- 22:24lesions of the talus, which are areas of damaged
- 22:26cartilage and underlying bone, occult or hidden
- 22:29syndesmotic injuries that weren't clear on x
- 22:31-ray, anterior or anterolateral synovitis, which
- 22:34is inflammation of the joint lining, or anterior
- 22:37ankle impingement, where soft tissues get pinched
- 22:39in the front of the ankle. So MRI for the complications
- 22:42or persistent symptoms. That's the general rule.
- 22:44Lastly, quick word on referral considerations.
- 22:48Orthopedic referrals are warranted for specific
- 22:50situations. This includes any suspected fractures
- 22:53that aren't clearly benign or simple on x -ray,
- 22:55any signs of neurovascular compromised numbness,
- 22:58tingling, diminished pulses. Durgent referral
- 23:01for those. Absolutely. Suspected tendon ruptures,
- 23:03such as the Achilles or perennial tendons, symptoms
- 23:06that are disproportionate to the trauma observed,
- 23:09perhaps indicating a more complex underlying
- 23:11issue, or if there's persistent diagnostic uncertainty
- 23:14after your initial thorough clinical and imaging
- 23:17workup. These are the cases that truly demand
- 23:19specialist input to ensure optimal outcomes.
- 23:22That's a truly comprehensive and incredibly practical
- 23:25roadmap for diagnosis, Professor. It really demystifies
- 23:29the initial clinical encounter. So once we've
- 23:31accurately diagnosed an ankle sprain and we've
- 23:34got a clear picture of its type and severity,
- 23:36the next critical hurdle is effective management.
- 23:40How do we best approach treatment from those
- 23:42initial conservative measures that apply to the
- 23:44vast majority of patients to considering surgical
- 23:47intervention for those specific, often more complex
- 23:49circumstances? I imagine it's a careful balance,
- 23:52particularly with athletes keen to return to
- 23:55play. It is indeed a careful balance and a multi
- 23:58-phased approach is key. For the overwhelming
- 24:00majority of low ankle sprains, including many
- 24:02severe grade three ligament tears, robust and
- 24:05effective healing can absolutely be achieved
- 24:07without the need for surgery provided they are
- 24:10appropriately immobilized initially and crucially
- 24:12diligently rehabilitated. So non -operative first
- 24:16for most. The vast majority. Non -operative treatment
- 24:19typically begins with initial management or phase
- 24:21one. This is where the well -known RICE protocol
- 24:24has historically held sway. Rest. Advise patients
- 24:28to avoid weight bearing on the injured ankle
- 24:30or resuming sports activities that aggravate
- 24:32it. For more severe sprains, particularly grade
- 24:35two or three, crutches may be recommended for
- 24:38a period to avoid weight bearing completely and
- 24:40allow initial healing. Ice. Immediate application
- 24:44helps significantly to reduce swelling and pain.
- 24:46Recommend applying an ice pack for 20 to 30 minutes,
- 24:49three to four times daily, ensuring it's wrapped
- 24:51in a cloth to prevent direct skin contact and
- 24:53potential ice burns. Compression. Using elastic
- 24:57bandages and ace wrap or compression stocking
- 24:59can help to both immobilize and support the ankle
- 25:01while also actively managing edema. Elevation.
- 25:05Instruct patients to raise their ankle above
- 25:06heart level as often as possible during the first
- 25:0848 hours. This uses gravity to help drain excess
- 25:11fluid and control swelling. Right, see everyone
- 25:13knows it. Everyone knows it. Now here's a critical
- 25:17insight that's shifting clinical practice. While
- 25:20rice has been a cornerstone for decades, recent
- 25:23evidence suggests its isolated effectiveness
- 25:25particularly the R for rest and the I for ice,
- 25:28is somewhat limited in terms of accelerating
- 25:30definitive healing beyond immediate pain and
- 25:33swelling control. Oh, interesting. So rice alone
- 25:35isn't the whole story. Not entirely. Strong evidence
- 25:39primarily supports cryotherapy, or ice, when
- 25:42combined with early controlled exercise therapy
- 25:44for truly improving functional outcomes. So it's
- 25:46not simply rest and ice. It's ice and move it
- 25:49judiciously. Bice and movement. Controlled movement,
- 25:52yes. It's also important to advise patients to
- 25:54avoid in the first two to three days. Heat, alcohol
- 25:58running, or excessive activity and massage, as
- 26:00these can exacerbate swelling and bleeding in
- 26:02the acute phase. Avoid harm, remember rice, with
- 26:05caveats. Exactly. Regarding immobilization, a
- 26:09short period of immobilization, perhaps around
- 26:11one week, in a walking boot, in an air cast,
- 26:13or a walking cast, may be required, particularly
- 26:16for gray Daseki's brains, or those with significant
- 26:19pain. For grade 3 sprains, a slightly longer
- 26:22period of casting or bracing for 10 -14 days
- 26:24with strict non -weight -bearing might be beneficial
- 26:27to protect the completely torn ligament in its
- 26:29initial healing phase. So immobilize, but not
- 26:33for too long? That's the key. The overarching
- 26:35principle that has emerged strongly in the last
- 26:37decade is that early mobilization generally facilitates
- 26:39a better and quicker recovery, leading to superior
- 26:42functional outcomes and less stiffness in the
- 26:44long run. So the immobilization period should
- 26:47always be as brief as clinically necessary, guided
- 26:49by the patient's pain levels and the stability
- 26:51of the injury. For medication, non -steroidal
- 26:54anti -inflammatory drugs or NSAIDs, such as ibuprofen,
- 26:58naproxen, or Celecoxib, are widely used for pain
- 27:01relief and swelling reduction. They are generally
- 27:04preferred over narcotic painkillers for mild
- 27:06to moderate sprains, as they improve function
- 27:08by addressing both pain and inflammation. Standard
- 27:11NSAIDs. Yes. However, And here's another nuanced
- 27:15insight for our listeners. It's worth noting
- 27:17the potential for NSI's to actually delay the
- 27:21natural healing process in some contexts. This
- 27:23is because they suppress the inflammatory response,
- 27:26which ironically is a necessary and initial component
- 27:29of the body's natural tissue repair process.
- 27:32Right. Inflammation is part of healing. It is.
- 27:34So while they provide symptomatic relief, we
- 27:36need to be mindful of this potential trade -off,
- 27:38especially in the very early stages of healing
- 27:41for more severe sprains. The true cornerstone
- 27:44of long -term recovery, particularly from phase
- 27:46two onwards, is dedicated physical therapy and
- 27:48rehabilitation. This is absolutely crucial irrespective
- 27:51of the initial severity. Physio is key. Absolutely.
- 27:54The early phase, phase two, or functional rehabilitation,
- 27:58begins once the initial acute swelling and pain
- 28:01have subsided, usually within a few days to a
- 28:03week. This involves gentle motion exercises,
- 28:06progressing quickly to isometric strengthening,
- 28:09proprioception training, and activity -specific
- 28:11exercises. It's vital that any rigid immobilization
- 28:14is discontinued at this stage to prevent joint
- 28:16stiffness and muscle atrophy. The goal here is
- 28:19to regain a pain -free range of motion. Strengthening
- 28:22phase, phase three, commences once full range
- 28:25of motion is achieved and pain is well under
- 28:27control. The primary focus here is on strengthening
- 28:29the peroneal muscles, the muscles on the outside
- 28:32of your lower leg, which are key dynamic stabilizers
- 28:34of the ankle and actively resistant version.
- 28:37Strengthening those outer muscles. Crucial. Neuromuscular
- 28:41training, which helps improve the brain's communication
- 28:43with the muscles, is integrated. Gradual incorporation
- 28:47of resistance exercises using bands, weights,
- 28:49or body weight is key. Water -based exercises
- 28:53like aqua jogging or exercises in a pool can
- 28:56be incredibly useful for patients who are still
- 28:58experiencing pain during land -based weight -bearing
- 29:00exercises as the buoyancy reduces load. Hydrotherapy
- 29:04can be great. Very helpful. Proprioception balance
- 29:07training is an absolutely essential component,
- 29:10particularly given that poor balance is a significant
- 29:12well -established risk factor for recurrent sprains
- 29:15and chronic instability. These exercises are
- 29:18designed to enhance the body's awareness of joint
- 29:20position and movement. Think of simple exercises
- 29:22like standing on the affected foot with eyes
- 29:24open, then progressing to eyes closed. Wobble
- 29:27boards and things like that. Exactly. Or using
- 29:30unstable surfaces like a wobble board or foam
- 29:32pad. These drills are not just about balance.
- 29:36They help to re -educate the nervous system,
- 29:38training faster, more reactive responses from
- 29:40the peroneal muscles during dynamic activities,
- 29:43helping the ankle to catch itself before it rolls.
- 29:46Endurance and agility exercises are gradually
- 29:48introduced once the patient is pain -free and
- 29:51has achieved good strength and balance. Examples
- 29:54include progressively smaller figure of eight
- 29:56running drills, side -to -side shuffles, or ladder
- 29:58drills. These improve agility, ankle strength,
- 30:01and calf endurance, simulating sport -specific
- 30:04movements. A functional brace that specifically
- 30:06controls inversion and eversion is typically
- 30:09recommended for use during the strengthening
- 30:10period and often as a prophylactic measure for
- 30:13high -risk activities, particularly in the early
- 30:15return to sport phase. Bracing for sport. Often
- 30:18advisable, especially initially. In terms of
- 30:21outcomes for non -operative treatment, consistent
- 30:23evidence shows that early functional rehabilitation
- 30:26consistently leads to the quickest return to
- 30:28physical activity and superior long -term outcomes.
- 30:31While supervised physical therapy shows early
- 30:34benefits in terms of patient confidence and adherence,
- 30:37there isn't convincing evidence of a significant
- 30:39long -term difference in outcome compared to
- 30:42a well -structured unsupervised home program
- 30:44for mild to moderate sprains, provided the patient
- 30:47is compliant. So home exercises can work well
- 30:50if done properly. They certainly can. Also, it's
- 30:53an important point for clinicians that there's
- 30:55no convincing evidence that the future development
- 30:57of chronic ankle instability can be reliably
- 30:59predicted solely by history, acute physical examination,
- 31:03or initial radiographic parameters. So a seemingly
- 31:06minor sprain can still lead to long -term issues
- 31:08if not rehabilitated properly. You can't always
- 31:10tell at the start. Not reliably, no. Return to
- 31:13play or activity varies significantly and must
- 31:16be individualized. It depends heavily on the
- 31:19sprains grade, whether there's syndesmosis involvement
- 31:21as high ankle sprains take longer, any associated
- 31:24injuries, and critically, the patient's compliance
- 31:27and progression through the rehabilitation program.
- 31:30As a general guideline, Grade 1 sprains typically
- 31:33allow return within 1 -2 weeks. Grade 2 sprains
- 31:37usually take 2 -4 weeks. Grade 3 sprains generally
- 31:40require 4 -8 weeks. And high ankle sprains? They
- 31:42take longer. For high ankle sprains managed with
- 31:45immobilization, recovery can be 6 -12 weeks.
- 31:48If screw fixation is required for a high ankle
- 31:50sprain to stabilize the syndesmosis, it could
- 31:53even be a season -ending injury for an athlete
- 31:55requiring 4 -6 months before return to sport.
- 31:58Overall, recovery can range from as little as
- 32:00two weeks for very minor sprains to three, six
- 32:03months for more severe complex injuries. Quite
- 32:05a range. A very wide range. Now, for operative
- 32:07treatment, it is thankfully rarely required for
- 32:10the majority of ankle sprains. Surgery is typically
- 32:12considered only for specific, well -defined circumstances.
- 32:15When does surgery come into play? The primary
- 32:17indications for surgery include persistent pain
- 32:20and chronic ankle instability. Despite an extensive
- 32:24and rigorous course of non -operative management,
- 32:27and we're talking about months of dedicated supervised
- 32:29rehabilitation, not just a few weeks. After failed
- 32:32conservative treatment. Yes, genuine failure
- 32:35despite best efforts. It might also be considered
- 32:38for great third sprains if there's a significant
- 32:40bony avulsion, meaning a piece of bone has been
- 32:42pulled off by the ligament. Certain high ankle
- 32:45sprains with clear tibiofibular diastasis, which
- 32:48is that pathological widening or separation between
- 32:50the tibia and fibula, often indicating a complete
- 32:53syndesmotic disruption, are also surgical candidates.
- 32:56Unstable high ankle sprain. Correct. Furthermore,
- 32:59if there are associated significant injuries
- 33:01identified, such as osteochondral lesions, cartilage
- 33:04damage on the talus, ruptured peroneal or other
- 33:07tendons, or significant impingement syndromes
- 33:09that don't respond to conservative care, then
- 33:12surgery may be necessary to address these concomitant
- 33:15issues. As for the types of surgery, arthroscopy
- 33:19is a minimally invasive keyhole procedure, often
- 33:22performed prior to open ligament reconstruction.
- 33:24It allows the surgeon to inspect the entire joint
- 33:27meticulously, identify and debride any impinging
- 33:30scar tissue or synovitis, or remove loose fragments
- 33:33of bone or cartilage that might be causing ongoing
- 33:35pain, catching, or mechanical symptoms. We look
- 33:37inside first. Often very helpful, yes. It's an
- 33:40excellent diagnostic tool as well as therapeutic.
- 33:42For the ligament repair or reconstruction itself,
- 33:45there are two main approaches. The gold standard
- 33:47for chronic lateral ankle instability is the
- 33:49anatomic reconstruction, famously exemplified
- 33:52by the Gould modification of the Brostrum procedure.
- 33:55That's the one. This procedure involves shortening
- 33:58and reinserting the ATFL and CFL to their anatomical
- 34:02origins and insertions, often reinforced with
- 34:05the inferior extensor retinaculum and distal
- 34:08fibular periosteum, which are local soft tissues
- 34:11providing additional strength. In more recent
- 34:13years, suture tape augmentation, where a strong
- 34:16tape is placed alongside the repair, has been
- 34:18shown to further increase the strength and early
- 34:21stability of this repair, allowing for potentially
- 34:23faster rehabilitation. Adding extra support.
- 34:26Exactly. A critical point to remember with this
- 34:29procedure is that if the ligaments are overtly
- 34:31lightened, it can unfortunately lead to a restricted
- 34:33range of dorsiflexion post -operatively causing
- 34:36stiffness. The outcomes for the Brostrom Gold
- 34:38are generally very good, with good to excellent
- 34:41results reported in about 90 % of cases. High
- 34:43success rate. Generally, yes. Alternatively,
- 34:47particularly in cases of severe instability,
- 34:50failed previous repairs, or significant tissue
- 34:52laxity, there are tendon transfer or tenodesis
- 34:55procedures. Examples include the Watson -Jones,
- 34:59Christman -Snoek, Colville, or Evans techniques.
- 35:02These are considered non -anatomic reconstructions
- 35:04because they don't recreate the original ligament
- 35:07anatomy directly. Instead, they use a segment
- 35:09of a healthy local tendon, often one of the peroneal
- 35:13tendons, which is then passed through bone tunnels
- 35:15to create a new functional restraint. Using a
- 35:18tendon instead of repairing the ligament. Correct.
- 35:21It's absolutely critical that any pre -existing
- 35:22foot or ankle malalignment, such as a hindfoot
- 35:25virus where the heel turns inward, is identified
- 35:27and corrected, often assessed with something
- 35:29like Coleman block testing before these procedures
- 35:32are undertaken, as malalignment can jeopardize
- 35:34the success of the reconstruction. You need to
- 35:36fix the alignment first. Absolutely essential.
- 35:39A common complication with these non -anatomic
- 35:41reconstructions due to their altered biomechanics
- 35:44can be subtalar stiffness, which can affect foot
- 35:47mobility. Postoperative recovery following surgery
- 35:51invariably involves a period of immobilization
- 35:54in a cast or protective boot typically for four
- 35:57to six weeks to safeguard the delicate repaired
- 36:00ligaments during their initial healing. Strict
- 36:03adherence to non -weight -bearing protocols during
- 36:05this crucial initial phase is absolutely critical
- 36:08to prevent re -tear of the surgical repair. Protecting
- 36:11the repair. Vitally important. Rehabilitation
- 36:14then commences, focusing intently on regaining
- 36:17strength and range of motion, similar in principle
- 36:19to conservative rehab, but often more gradual
- 36:22initially. Recovery takes weeks to many months,
- 36:25depending on the extent of the original injury
- 36:27and the specific type of surgery performed. While
- 36:30some newer mobilization protocols advocate for
- 36:32earlier postoperative mobilization to improve
- 36:34functional scores, it's a careful balance, as
- 36:37they can also potentially lead to increased ankle
- 36:39laxity and a slightly higher risk of wound healing
- 36:41complications if not managed meticulously. That
- 36:44distinction between non -operative and operative
- 36:47strategies and the intricate nuances within each
- 36:49is incredibly insightful, profess. It highlights
- 36:52the depth of decision -making involved. But as
- 36:55the old saying goes, and it holds so true here,
- 36:57prevention is always better than cure. How can
- 37:01we as clinicians truly empower our patients,
- 37:03especially our athletes, like our hypothetical
- 37:05netball player Sarah, who just wants to get back
- 37:08on court without constant fear to proactively
- 37:10reduce their risk of both initial ankle sprains
- 37:13and critically those debilitating recurrent injuries?
- 37:16This is indeed a vital area. and one where we
- 37:19can make a tremendous impact on a patient's long
- 37:21-term quality of life. It genuinely requires
- 37:23a multifaceted approach, empowering patients
- 37:26to be proactive and consistently maintaining
- 37:28their ankle strength, balance, and flexibility.
- 37:30For us as clinicians, the focus must be on targeting
- 37:33and modifying any identifiable intrinsic and
- 37:36extrinsic risk factors. Tackling those risk factors
- 37:39we talked about. Exactly. One of the most fundamental,
- 37:42yet often overlooked, aspects is footwear selection.
- 37:45This is absolutely crucial for providing adequate
- 37:48support and stability. For individuals whose
- 37:51feet pronate excessively or who have naturally
- 37:53low arches, often referred to as flat feet, advise
- 37:57them to opt for shoes that offer robust arch
- 37:59and front foot support, coupled with a stable,
- 38:02firm heel counter. Supporting the flat foot?
- 38:05Yes, controlling that inward roll. Conversely,
- 38:08those with stiffer feet or high arches, a cavalvaris
- 38:10alignment, for example, may benefit more from
- 38:13cushioned and softer platforms, as their feet
- 38:15are inherently less shock -absorbent. It goes
- 38:18without saying that sport -specific shoes are
- 38:20highly recommended. A runner needs running shoes
- 38:22designed for gait, a basketball or netball player
- 38:25needs court shoes with good lateral support and
- 38:27grip, and so on. Right tool for the job. Precisely.
- 38:30General cross -training shoes, while versatile,
- 38:33may not offer the precise support and stability
- 38:35needed for specific high -demand activities,
- 38:37and importantly, advise regular replacement of
- 38:40athletic shoes typically every six months for
- 38:42regular runners, or even more frequently if the
- 38:44tread wears out or the shoe's cushioning and
- 38:47support degrade prematurely. A simple check is
- 38:50if the midsole feels flat or compressed. Don't
- 38:52wear worn -out trainers. A simple but effective
- 38:54message. Beyond footwear, Exercise -based prevention
- 38:58truly forms the core of a robust program. Strengthening
- 39:01exercises are key to improving dynamic ankle
- 39:04stability. This includes simple calf raises,
- 39:07resistance band ankle exercises to target various
- 39:09planes of motion, dorsiflexion, plantar flexion,
- 39:12inversion, and aversion, and critically specific
- 39:15and dedicated strengthening of the evertoor muscles,
- 39:18particularly the peroneals. Again, those peroneal
- 39:20muscles. They're the active stabilizers, resisting
- 39:23that inversion force. Propreception exercises
- 39:26are absolutely essential. Given that poor balance
- 39:29and diminished joint awareness are such significant
- 39:32risk factors for recurrent sprains, exercises
- 39:35that enhance the conscious and subconscious awareness
- 39:37of joint position and movement are paramount.
- 39:40Think of single leg balance exercises. Progressively
- 39:42perform first with eyes open, then with eyes
- 39:45closed to remove visual cues, or using unstable
- 39:48surfaces like a wobble board, balance disc, or
- 39:50foam pad. Training that balance reaction. Exactly.
- 39:53These drills are profound. They help to re -educate
- 39:56the nervous system, training faster, more accurate
- 39:59neuromuscular responses from the peroneal and
- 40:01other stabilizing muscles during dynamic activities,
- 40:05helping the ankle to catch itself and correct
- 40:07its position milliseconds before a sprain occurs.
- 40:10A structured warm -up routine, including dynamic
- 40:13stretches and light cardiovascular activity targeting
- 40:15the lower limbs, should always proceed any physical
- 40:17activity. This prepares the muscles and ligaments
- 40:20for the demands of the activity, increasing blood
- 40:23flow and elasticity, thereby reducing injury
- 40:25risk. And for those returning to sport or higher
- 40:28-level activities, incorporating progressive
- 40:30drills like quick support drills, shuttle runs,
- 40:32and dynamic landings can further enhance neuromuscular
- 40:35control, agility, and stability in sport -specific
- 40:38contexts. These drills mimic the demands of their
- 40:41sport, building confidence and resilience. Maintenance
- 40:44and activity modification are also critical for
- 40:46long -term success. Encourage patients to regularly
- 40:49include balance and strengthening exercises in
- 40:51their routine, perhaps two to three times per
- 40:53week, even when they feel completely well and
- 40:55pain -free. Keep doing the exercises. It isn't
- 40:58just rehabilitation. It's preventative maintenance.
- 41:01Furthermore, advise them to be mindful of and,
- 41:04whenever possible, avoid high -risk situations,
- 41:07stepping on uneven or slippery surfaces, especially
- 41:10when fatigued or distracted, significantly increases
- 41:13vulnerability to injury. Sometimes, just being
- 41:16aware of your environment can prevent an incident.
- 41:19Finally, when we consider return to activity
- 41:21for athletes like Sarah, it must be a meticulously
- 41:24gradual transition to sport -specific activities,
- 41:27ensuring full functional recovery, confidence,
- 41:29and assessed readiness before resuming previous
- 41:31intensity levels. For athletes with a history
- 41:34of prior sprains, a comprehensive prevention
- 41:36program is particularly important. And this may
- 41:39indeed include the consistent use of semi -rigid
- 41:41ankle orthosis or taping, especially for those
- 41:44who demonstrate a cavovirus foot alignment to
- 41:46provide that essential additional mechanical
- 41:48support and proprioceptive feedback. Bracing
- 41:51or taping for those at higher risk? It can make
- 41:53a real difference. Implementing these measures
- 41:55consistently can dramatically reduce the risk
- 41:57of both initial ankle sprains and, crucially,
- 42:00that frustrating cycle of recurrence. That's
- 42:02a truly powerful message on Prevention Prof,
- 42:04emphasizing that our role extends far beyond
- 42:07merely treating the acute injury. It's about
- 42:10empowering patients to stay robust. But even
- 42:13with the best care, diligent rehab, and robust
- 42:15prevention strategies, complications can, unfortunately,
- 42:19arise. What are the potential long -term complications
- 42:22of ankle sprains, and how do we, as clinicians,
- 42:25best identify and manage them to ensure optimal
- 42:28patient outcomes, avoiding that debilitating
- 42:30cycle of reinjury and chronic issues? This is
- 42:33a critical discussion, because while the majority
- 42:35of ankle sprains do heal well with proper management,
- 42:38we absolutely cannot overlook the significant
- 42:40potential for long -term term consequences if
- 42:42they are not correctly identified, managed or
- 42:45rehabilitated. The most immediate and significant
- 42:48risk following an ankle sprain, especially if
- 42:49the ankle isn't adequately healed and strengthened
- 42:51before resuming full physical activity, is re
- 42:54-injury. Going over on it again. Exactly. The
- 42:57structural integrity of the ankle has been compromised,
- 42:59even if subtly, making it inherently more susceptible
- 43:02to future sprains. Each re -injury can progressively
- 43:05worsen the joint's stability. A notable and pervasive
- 43:09long -term consequence affecting a significant
- 43:11proportion of patients is chronic ankle instability,
- 43:14or CAI. This develops in an estimated 15 % to
- 43:1820 % of patients, particularly when an initial
- 43:20ankle sprain, especially a severe one like a
- 43:23grade II or III, isn't allowed to heal completely
- 43:25or isn't adequately rehabilitated. 15 to 20 %
- 43:28is quite high. It is worryingly high. CAI is
- 43:32clinically characterized by persistent pain,
- 43:34ongoing swelling that seems to come and go, and
- 43:36most tellingly, the ankle repeatedly giving way
- 43:39or feeling profoundly unstable during weight
- 43:41-bearing activities, even on flat ground. That
- 43:43feeling of untrustworthiness. Precisely. It can
- 43:46be the result of a single, severe, inadequately
- 43:49rehabilitated sprain or the cumulative effect
- 43:52of multiple recurrence sprains that progressively
- 43:54stretch and weaken the ligaments. This chronic
- 43:57instability often leads to debilitating chronic
- 43:59pain, significant difficulty with activities
- 44:01like walking, running, or playing sports, and
- 44:04in the very long term dramatically increases
- 44:07the risk of developing early onset osteoarthritis
- 44:09and further damage to the underlying articular
- 44:11cartilage and bone within the joint due to abnormal
- 44:14loading patterns. Leading to arthritis down the
- 44:16line. A very real risk. When we look at long
- 44:19-term symptom statistics, the data is quite sobering.
- 44:22Research indicates that between 5 % and 46 %
- 44:25of patients report lingering pain years after
- 44:27their initial injury, and a staggering 33 % to
- 44:3055 % continue to experience a sensation of instability
- 44:34or giving way. Wow, over half in some studies.
- 44:37Yes. While acute pain typically decreases rapidly
- 44:40within the first two weeks post -injury, a notable
- 44:43percentage between 5 % and 33 % still report
- 44:46some level of pain even at one -year follow -up.
- 44:49This powerfully highlights that simply getting
- 44:52over the acute pain is by no means indicative
- 44:55of full recovery or resolution of the underlying
- 44:57issue. A significant and often overlooked cause
- 45:00of persistent chronic pain following an ankle
- 45:03sprain is actually a missed initial injury. These
- 45:06are often subtle but clinically significant pathologies
- 45:08that weren't picked up in the acute phase. Exactly.
- 45:12This can include missed fractures, such as those
- 45:14to the base of the fifth metatarsal, the anterior
- 45:16process of the calcaneus, or more subtle fractures
- 45:18of the lateral or posterior process of the talus.
- 45:21Osteochondral lesions, which are areas of damage
- 45:23to the articular cartilage and the underlying
- 45:25bone, most commonly affecting the talus. These
- 45:28can cause persistent pain, catching, or locking
- 45:31sensations. Injuries to the coronial tendons,
- 45:33which are key dynamic stabilizers. These can
- 45:35involve tenosynovitis, subluxation, or even full
- 45:38ruptures. An undiagnosed or inadequately treated
- 45:41syndesmosis injury, high ankle sprain, which
- 45:44as we discussed is far more severe and takes
- 45:46much longer to heal. Tarsal coalition, which
- 45:48is an abnormal fibrous, cartilaginous, or bony
- 45:50connection between two or more bones in the hindfoot.
- 45:53It can predispose to sprains and become symptomatic
- 45:55after trauma. Various impingement syndromes,
- 45:57such as anterior or anterolateral synovitis,
- 46:00inflammation of the joint lining in the front
- 46:01of the ankle, or impingement of the anterior
- 46:04or inferior tibiofibular ligaments from scar
- 46:07tissue. Interlying hindfoot varus malalignment,
- 46:10which places chronic stress on the lateral ankle
- 46:12structures. Or even stretch neuropraxia. where
- 46:15a peripheral nerve, often the superficial peroneal
- 46:18nerve, has been stretched or compressed during
- 46:20the spraying, leading to neuropathic pain or
- 46:23altered sensation in its distribution. Quite
- 46:25a list of potential missed problems. It requires
- 46:28a high index of suspicion. A truly thorough clinical
- 46:32evaluation is thus paramount to prevent these
- 46:35crucial oversights. The overall prognosis for
- 46:38ankle sprains is generally positive with proper
- 46:40treatment and dedicated rehabilitation. However,
- 46:44the ultimate success of recovery is highly dependent
- 46:46on the initial sprain grade, the presence or
- 46:49absence of any other associated injuries, both
- 46:51diagnosed and those that might have been initially
- 46:53missed, and, critically, the patient's unwavering
- 46:56commitment to their rehabilitation program. Patient
- 46:59compliance is vital. Absolutely vital. Incomplete
- 47:02rehabilitation is, without doubt, the most common
- 47:04single cause of chronic ankle instability and
- 47:07subsequent re -injury. Patients who discontinue
- 47:10their strengthening and balance exercises prematurely
- 47:13will inevitably find their injured ligaments
- 47:15and the surrounding dynamic stabilizers weaken,
- 47:18putting them at exceedingly high risk for future
- 47:20sprains. It's also crucial to counsel patients
- 47:23that while surgical interventions are sometimes
- 47:25absolutely necessary for chronic instability
- 47:28or other associated complications, they do carry
- 47:31their own inherent risks. These can include the
- 47:33general risk of surgery like infection or nerve
- 47:35damage, a potentially prolonged recovery period
- 47:38with strict immobilization, and the unfortunate
- 47:40possibility of some residual loss of ankle range
- 47:43of motion postoperatively, even with the best
- 47:45surgical technique. Surgery isn't without its
- 47:47own issues. Never. So the decision for surgery
- 47:50is always a careful considered one, weighing
- 47:52these risks and potential benefits against the
- 47:54patient's individual circumstances and goals.
- 47:57Our aim is always to guide the patient to the
- 47:59best long -term outcome, whether that's with
- 48:01or without a scalpel. often long -term impact
- 48:06of seemingly simple injuries and highlights the
- 48:09absolute imperative for comprehensive, diligent,
- 48:12and patient -centered care. Prof. Moimam, you've
- 48:15guided us through an incredibly detailed and
- 48:18remarkably insightful deep dive into ankle sprains.
- 48:21From the foundational anatomical understanding
- 48:23and nuanced classification through to the comprehensive
- 48:26treatment strategies and crucially, those vital
- 48:29prevention methods, you've provided an invaluable
- 48:32actionable overview for all of us as mid -senior
- 48:35medical professionals. What really stands out
- 48:38from our conversation today is the absolute importance
- 48:40of a thorough clinical approach right from the
- 48:42outset, meticulously ruling out those missed
- 48:45injuries, coupled with an unwavering commitment
- 48:47to comprehensive and often prolonged rehabilitation.
- 48:50These elements are unequivocally key to mitigating
- 48:53those potential long -term complications we've
- 48:55discussed, ensuring our patients don't get caught
- 48:57in that frustrating cycle of chronic pain and
- 48:59instability. We genuinely hope this deep dive
- 49:02has offered you some new perspectives, perhaps
- 49:03at clarified some complex areas or reinforced
- 49:06critical best practices in your own clinical
- 49:08encounters. If you found this deep dive valuable,
- 49:11please consider rating and sharing it with your
- 49:12colleagues. It truly helps us reach more professionals
- 49:15like you. My pleasure entirely. To leave you
- 49:17with a final thought. While ankle sprains are
- 49:21indeed ubiquitous and almost daily occurrence
- 49:23in our clinics, our continually evolving understanding
- 49:26of ankle biomechanics, the sophisticated rehabilitation
- 49:29principles we now have at our disposal, and the
- 49:32advanced surgical techniques available offer
- 49:34us genuinely significant opportunities. The true
- 49:38challenge for us as orthopedic professionals
- 49:40lies not just in knowing these advancements,
- 49:42but in the consistent, meticulous, and diligent
- 49:45application of these principles in every single
- 49:47clinical encounter. Because ultimately, this
- 49:49isn't just about treating an injury, it's about
- 49:51fundamentally preventing debilitating long -term
- 49:53consequences, and more broadly, significantly
- 49:56enhancing our patient's overall quality of life.
