Dislocation of the talus is a serious and extremely rare injury, with 86 cases reported in the published data in 20 years. The reference standard for case management involves replacement of the dislocated talus to restore the height and function of the tibiotalar joint. The risk of avascular necrosis remains very high, and the standard treatment in such cases is tibiotalar arthrodesis. We report the case of total dislocation of the talus, which was treated with the insertion of a custom total talar prosthesis affixed directly to the tibial cartilage at 6 months after injury...

BACKGROUND: Pantalar dislocations without associated talar fracture are rare and have high risks of complications, including infection, osteonecrosis, and posttraumatic osteoarthrosis. Limited information on later function exists. This study evaluated complications and outcomes following pantalar dislocation without talar fracture. METHODS: Nineteen patients were identified with open (n = 14) or closed (n = 5) pantalar dislocations without talar fracture. Ten male and 9 female patients with a mean age of 39...

PURPOSE: The impact of isolated malleolar fractures on the intra-articular load distribution within the ankle joint has been studied in several biomechanical cadaver studies during the last decades. Recently, computed tomography osteoabsorptiometry (CT-OAM) has been proposed as a valuable tool to assess intra-articular joint load distribution in vivo. The purpose of this retrospective matched pair analysis was to apply CT-OAM to evaluate in vivo changes of talar load distribution after lateral malleolar fractures in patients treated with open anatomic reduction and internal fixation (ORIF) compared to patients treated non-operatively...

Pure ankle dislocation is a rare event that primarily results from high-energy trauma. Predisposing anatomical factors such as talar hypoplasia, ligament laxity, and previous sprains may play a key role. This report presents the case of a 55-year-old man with fatal anterior and posterior tibial artery tears following a pure anterolateral dislocation of the right ankle. To the best of our knowledge, no such cases have previously been reported in the English-language literature.

BACKGROUND: Mobile-bearing total ankle replacement (TAR) enables motion at the tibial implant-polyethylene insert interface. This motion could lead to coronal translation of the talus relative to the tibia and may affect radiographic outcome. We aimed to assess the translation of the talus before and after mobile-bearing TAR to determine whether translation of the talus after TAR is associated with coronal plane alignment of the lower limb and hindfoot as well as to investigate the complications associated with talar translation...

We report the unusual case of a 16-year-old young man who sustained a rare association of a Hawkins' type-II talar neck fracture with a complete medial subtalar dislocation (Hawkins type-IIB) that occurred as an isolated injury after indirect trauma during a soccer game. Following closed reduction of the subtalar dislocation, standard radiographs and computed tomography (CT) demonstrated a comminuted fracture of the talus involving the base of the talar neck. Open reduction was performed and the fracture was stabilized by ORIF...

Introduction Talar dislocation fractures of type IV (Marti and Weber) are extremely rare injuries with special challenges to the surgeon and poor results. Due to their low incidence and the sparse literature, it is unclear what is the optimal treatment and how complications can be minimised. Material and Methods A literature research was carried out using the online medical database "PubMed". The findings of the literature were then applied to a clinical case of type IV talar dislocation fracture (Marti and Weber)...

PURPOSE OF THE STUDY Peripheral fractures of the talus (lateral talar process and posterior talar process) are rare injuries, easy to miss on examination due to their location and clinical manifestation. They account for 0.3% to 1.0% of all fractures of the talus. An incorrect or late treatment of talar process fractures can result in permanent pain, impingement syndrome, healing in malposition, pseudoarthrosis development and also, due to joint instability, in a potential development of severe subtalar arthritis...

Isolated posteromedial ankle dislocation is a rare condition thanks to the highly congruent anatomical configuration of the ankle mortise, in which the medial and lateral malleoli greatly reduce the rotational movement of the talus, and the strength of the ligaments higher than the malleoli affords protection against fractures. However, other factors, like medial malleolus hypoplasia, laxity of the ligaments, peroneal muscle weakness and previous ankle sprains, could predispose to pure dislocation. In the absence of such factors, only a complex high-energy trauma, with a rotational component, can lead to this event...

A case of complicated lateral subtalar dislocation is presented and the literature concerning this injury is reviewed. Subtalar joint dislocations are rare and often the result of a high-energy trauma. Complications include avascular necrosis of the talus, infection, posttraumatic osteoarthritis requiring arthrodesis and chronic subtalar instability. Negative prognostic factors include lateral and complicated dislocations, total talar extrusions, and associated fractures. A literature search was performed to identify studies describing outcome after lateral subtalar joint dislocation...

The purpose of this study was to assess the incidence of tendon entrapments and tendon dislocations associated with ankle and hindfoot fractures in patients studied by multidetector computed tomography (MDCT). Additionally, we describe particular tendon injuries associated with specific fractures. This was a retrospective review of all individuals with a trauma-protocol CT for suspected ankle and/or hindfoot fractures during a consecutive 41-month time period at a single Level I Trauma Center. Each patient's images were evaluated by two radiologists and an orthopedic surgeon for tendon entrapment, tendon dislocation, and bone(s) fractured or dislocated...

Fractures of the talar neck with subtalar and tibiotalar joint dislocation (AO/OTA 81-B3) represent a treatment challenge for the orthopedic surgeon. The magnitude of deformity and complexity of the pathoanatomy adds to concerns for soft tissue embarrassment to convey an urgency of surgical intervention. Previous studies have described the several techniques for talar reduction, including medial malleolar osteotomy, posterior Schanz pin manipulation, or posteromedial incision to facilitate relocation at the time of definitive open treatment...

INTRODUCTION: Talar fractures are a rare type of fractures (less than 1%). They are difficult to treat and outcome is often complicated by arthritis and avascular necrosis. In this article three cases are presented with different types of dislocated talar neck fractures. Anatomy of the talus, treatment, outcome and follow up of these fractures are discussed. Further, review of literature and guidelines for treatment and follow up for dislocated talar neck fractures are discussed. DISCUSSION: The risk of developing arthritis or avascular necrosis of the talus after dislocated talar neck fractures depends on the initial trauma with vascular compromise due to dislocation of the talus...

Heather A Vallier
UNLABELLED: Talus fractures occur rarely but are often associated with complications and functional limitations. Urgent reduction of associated dislocations is recommended with open reduction and internal fixation of displaced fractures when adjacent soft tissue injury permits. Delayed definitive fixation may reduce the risks of wound complications and infections. Restoration of articular and axial alignment is necessary to optimize ankle and hindfoot function. Despite this, posttraumatic arthrosis occurs frequently after talar neck and body fractures, especially with comminution of the talar body...

Subtalar dislocations were first described in 1811 as the simultaneous dislocation of the talo-calcaneal and talo-navicular joints without any tibio-talar or talar neck associated fractures. They were classified in 1853 as: medial, lateral, posterior and anterior based on the displacement of the foot in relationship to the talus. These are uncommon injuries, representing approximately 1 % of all traumatic injuries of the foot and 1-2 % of all dislocations, being associated with high energy trauma.Closed reduction of these dislocations should be performed as early as possible to avoid further damage to the skin and neurovascular structures...

REVIEW
Stefan Rammelt, Jens Goronzy
Subtalar dislocations make up 1-2% of all dislocations, about 75% of them being medial dislocations. Treatment consists of early reduction under adequate sedation. In cases of soft tissue interposition or locked dislocations, open reduction is warranted. More than 60% of subtalar dislocations are associated with additional fractures, therefore a postreduction CT is recommended. Complications include avascular necrosis of the talus, infection, posttraumatic arthritis, chronic subtalar instability, and complex regional pain syndrome with delayed reduction...

Open total talar dislocation is a rare but well known injury. Its management is controversial and fraught with complications such as infection, avascular necrosis, and post-traumatic osteoarthritis. We report the case of a woman sustaining a pure open talar dislocation reduced in the emergency room. Debridement was done three days after the injury in the operating room. There was no infection. One year after surgery she complained of occasional pain. Ambulation was normal. She wore regular shoes. The overall alignment of the ankle, hindfoot, and midfoot was normal...
