Talus Fracture

Talus Fracture

Talus bone forms the other half of ankle joint. It has some special characteristics that differentiates it from other bone of the body. It does not have any muscular attachment, its most of the surface area consist of articular surface that articulate with tibia, fibula, calcaneum and navicular bone and thus connects the leg with hind foot and mid foot. Talus is a very dense cancellous bone with thick cartilage covering on its articular surface. Main blood supply of talus enters through the proximal part of the bone. It is divided in to body, neck and head. Neck is most weak part of the bone where majority of talus fracture happens. Due to the peculiarity of blood supply after talus neck fracture the body of talus poses higher risk for developing avascular necrosis. Due to this grave consequence of this fracture surgical fixation is recommended in most of the talus neck fracture. Even fracture of body also poses higher risk of developing ankle arthritis. A similar grave outcome like talus neck fracture. Although surgical intervention is inevitable in most of the talus fracture the outcome of the surgery remains guarded in most of the time.
