[Fracture dislocation of the ankle with retro-tibial luxation of the fibula (Bosworth fracture) . Apropos of a case].

The authors present a case of fracture dislocation of the ankle joint with the proximal part of the fibula entrapped behind the tibia ; Bosworth's fracture. This fracture was described for the first time in 1848 by Hugier, and classified by Bosworth in 1947. In our case, diagnosis was not done in a first time, and closed reduction failed. This fracture was operated on and open reduction was performed. At the present time, the functional result is good.
