Abstract
Talus is a peculiar bone as almost 78% of its total bony surface is intra-articular. It transmits the entire body weight and has hardly any musculo-tendinous attachments [1]. Hence its injuries especially fractures and fracture dislocations, though not common, have posed a great deal of problems to orthopaedic surgeons in the form of open wound, skin necrosis from bony pressure, imperfect reduction and avascular necrosis [2-4]. As more than two third of the talus is intraarticular, very limited surface area is available to provide adequate vascular perforations. Blood vessels enter the talus via capsular and ligamentous attachment. Therefore, it is vulnerable to complication such as osteonecrosis after fracture and dislocation of talus [5].
