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...

REVIEW

Posterior malleolus fractures vary in morphology. A computed tomography scan is imperative to evaluate fragment size, comminution, articular impaction, and syndesmotic disruption. Despite an increasing body of literature regarding posterior malleolus fractures, many questions remain unanswered. Although, historically, fragment size guided surgical fixation, it is becoming evident that fragment size should not solely dictate treatment. Surgical treatment should focus on restoring ankle joint structural integrity, which includes restoring articular congruity, correcting posterior talar translation, addressing articular impaction, removing osteochondral debris, and establishing syndesmotic stability...

: In ankle fractures, the result of a gravity stress radiographic examination is clinically used to determine if a patient may need surgical intervention. The purpose of this study is to report the results of a gravity stress examination in the normal patient population. Fifty study participants were prospectively enrolled and complete ankle radiographs were obtained, including a nonweightbearing gravity stress examination. The mean medial clear space in the gravity stress view was 3...

Previous studies of frontal crash databases reported that ankle fractures are among the most common lower extremity fractures. While not generally life threatening, these injuries can be debilitating. Laboratory research into the mechanisms of ankle fractures has linked dorsiflexion with an increased risk of tibia and fibula malleolus fractures. However, talus fractures were not produced in the laboratory tests and appear to be caused by more complex loading of the joint. In this study, an analysis of the National Automotive Sampling System - Crashworthiness Data System (NASS-CDS) for the years 2004-2013 was conducted to investigate foot-ankle injury rates in front seat occupants involved in frontal impact crashes...

We report two cases of acute fractures of the os trigonum. The os trigonum fracture related to the first case was sustained following a hyper-plantar flexion injury during a game of soccer. The second case involved a patient who fell from height and also sustained open fractures of the left distal tibia and lateral malleolus as well as the right calcaneus. In both cases, a preliminary diagnosis of a posterior talar process fracture was made from the initial radiographs of the ankle. The correct diagnosis of an os trigonum fracture rather than a fracture of the posterior talar process was only made following further assessment with CT imaging...

BACKGROUND: Lisfranc (tarsometatarsal joint) injuries are relatively rare, accounting for less than 1% of all fractures, and as many as 20% of subtle Lisfranc injuries are missed at the initial patient presentation. An undiagnosed Lisfranc injury can have devastating consequences to the patient. Therefore, any factor that can raise a clinician's index of suspicion to make this diagnosis is potentially important. The cavus foot has been associated with various maladies of the lower extremity, but to our knowledge, it has not been reported to be associated with Lisfranc injury...

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...

Misalignment of the talar neck after surgical repair can redistribute the load among the posterior, middle, and anterior facets of the subtalar joints, which can change the joint biomechanics, cause arthritis, and impair function. However, we found no studies analyzing the plantar pressures after treatment of talus neck fracture. We determined the dynamic plantar pedobarographic and radiographic characteristics and ankle range of motion, function, and pain among patients after surgical repair of talar neck fractures...

BACKGROUND: The talus has a very complex anatomical morphology and is mainly fractured by a major force caused by a fall or a traffic accident. Therefore, a talus fracture is not common. However, many recent reports have shown that minor injuries, such as sprains and slips during sports activities, can induce a talar fracture especially in the lateral or posterior process. Still, fractures to the main parts of the talus (neck and body) after ankle sprains have not been reported as occult fractures...

BACKGROUND: Open surgical access to the postero-lateral talar dome for the treatment of osteochondral lesions is challenging, often requiring a segmental osteotomy of the fibula (fibular window) and division of the anterior inferior tibiofibular ligament (AITFL) or a fibular osteotomy with division of the AITFL and the anterior talofibular ligament (ATFL) (fibular door). Alternatively, to preserve the tibiofibular syndesmosis both the fibula and the lateral tibial plafond can be osteotomised to expose the entire lateral talar dome...

BACKGROUND: Screws placed from posterior to anterior have been shown to be biomechanically and anatomically superior in the fixation of talar neck and neck-body fractures, yet most surgeons continue to place screws from an anterior start point. The safety and efficacy of percutaneously applied posterior screws has not been clinically defined, and functional outcomes after their use is lacking. METHODS: After institutional review board approval, we performed a retrospective review of 24 consecutive talar neck fractures treated by a single surgeon that utilized posterior-to-anterior screw fixation...

Background: Talus fractures are rare and often result from axial trauma. As most of the talus surface is covered by cartilage, the blood supply is limited. Thus talus fractures are seen as one of the most severe fractures and often lead to significant long-term complications. Several studies suggest that the initial fracture classification can lead to correct treatment and that this can influence the long-term outcome. The aim of the current study was to investigate the importance of the initial fracture classification in respect to the radiological outcome in a large patient cohort...

Osteochondromas are the most common benign bone tumors. They are usually asymptomatic and found incidentally. When symptomatic, the symptoms are usually due to its location and size. Fracture of an osteochondroma presenting as posterior ankle impingement is a rare condition. We describe a 22-year-old man with solitary exostosis who presented with a posterior ankle mass and posterior ankle impingement with 2 years of follow-up. Surgical intervention was the treatment of choice in this patient, and histologic examination revealed a benign osteochondroma...

BACKGROUND: Ankle fusion has been the traditional treatment of choice for failed total ankle arthroplasties or arthritic conditions that preclude the use of primary implants. A custom stemmed agility talar component was designed to be used in these conditions. METHODS: The first 30 cases by a single surgeon were reviewed at two intervals. The study was a retrospective chart review with data including ankle diagnosis, deformity, bone loss and other factors that may have an impact on ankle arthroplasty...

BACKGROUND: Osteochondral lesions (OCLs) associated with ankle fracture correlate with unfavorable outcome. The goals of this study were to detect OCLs following ankle fracture, to associate fracture type to OCLs and to investigate whether OCLs affect clinical outcome. METHODS: 100 ankle fractures requiring operative treatment were prospectively included (46 men, 54 women; mean age 44 ± 14 years, range 20-77). All ankle fractures (conventional radiography; 71 Weber B, 22 Weber C, 1 Weber A, 4 isolated medial malleolus and 2 isolated posterior malleolus fractures) were treated by open reduction and internal fixation...
