Lateral talar process fragment excision may be followed by hindfoot instability and altered biomechanics. There is controversy regarding the ideal fragment size for internal fixation versus excision and a concern that excision of a large fragment may lead to significant instability. The aim of this study was to assess the effect of a simulated large lateral talar process excision on ankle and s...

Introduction: The ankle syndesmosis is a critical articulation between the distal tibia and fibula and is comprised of the anterior-inferior tibiofibular ligament (AITFL), interosseous ligament (IOL), interosseous membrane, posterior-inferior tibiofibular ligament (PITFL) and inferior transverse ligament (ITL) [1, 2]. The detrimental effects of syndesmotic malreduction have been documented in t...

Open hindfoot injuries result from high-energy trauma and include soft tissue disruption, joint dislocations, with possible chondral and osseous injuries. The term “total talus dislocation”, is an uncommon open hindfoot injury associated with talar extrusion. However, a total talus dislocation without extrusion has not been reported. This case presents an open hindfoot injury with dislocations ...

Introduction: The most common cause of ankle osteoarthritis (OA) is posttraumatic, with around 80% of all cases, followed by primary and secondary ankle OA. Patients often present wit asymmetric involvement of the tibiotalar joint, resulting in valgus or varus deformity of the ankle and hindfoot. The etiology of asymmetric arthritic ankles can be divided into 2 main etiologic and morphologic gr...

Acute ankle injury is one of the most common problems in sports medicine. Although most are ankle sprains, dislocations are occasionally seen. The case is presented of a closed posteromedial ankle dislocation without fracture which occurred during a basketball match. The literature is also reviewed.

Ankle distraction is an alternative to ankle arthrodesis or total ankle arthroplasty in younger patients with arthritis. Ankle distraction involves the use of external fixation to mechanically unload the ankle joint, which allows for stable, congruent range of motion in the setting of decreased mechanical loading, potentially promoting cartilage repair. Adjunct surgical procedures are frequentl...

The ankle is a common site of painful symptoms in athletes and nonathletes. Posterior ankle pain can be the end result of several pathologies, and a diagnostic challenge for rheumatologists. The posterior ankle impingement syndrome, also known as os trigonum syndrome and posterior tibiotalar compression syndrome, is a clinical disorder characterized by acute or chronic posterior ankle pain trig...

Introduction In virtually unloaded conditions, the tibiotalar (ankle) joint behaves as a single degree-of-freedom system, and two fibres within the calcaneal-fibular and tibio-calcaneal ligaments remain nearly isometric throughout the flexion arc [1]. A relevant theoretical model also showed that three articular surfaces and two ligaments act together as a mechanism to control the passive kinem...
