Abstract
Fractures of the talus are uncommon injuries that can have devastating consequences. The blood supply to the talus is tenuous and injuries are associated with a higher incidence of avascular necrosis and malunion. Talar neck fractures are the most common fractures. This review looks at the different types of fractures of the talus, particularly focusing on talar neck fractures. The diagnosis and management are discussed as well as the complications.
Highlights
Fractures of the talus are uncommon, accounting for approximately 0.1% of all fractures
Fractures of the talus are associated with significant morbidity in view of the blood supply, and these can be challenging for surgeons to manage [2]
Snowboarders are at increased risk of lateral process fractures due to the forces involved in landing a jump and the position of the feet when hitting the ground [7]
Summary
Fractures of the talus are uncommon, accounting for approximately 0.1% of all fractures. Fractures of the talus were first described in parachutists and pilots of the Royal Air Force who sustained these injuries upon impact with the ground, termed aviator’s astragalus [4, 5]. Fractures of the talus can be classified by their anatomical locations, and include talar neck, head, body, lateral process and posterior process fractures. Of these fractures, talar neck fractures are the most common. Optimal reduction often necessitates both anteromedial and anterolateral exposures during reduction and fixation [8] This method of reduction and fixation is a possible explanation for reduced morbidity and better results. We describe the anatomy and clinical presentation of these injuries
