Two stage reconstruction for the Shepherd's crook deformity in a case of polyostotic fibrous dysplasia.

Polyostotic fibrous dysplasia leads to progressive and disabling deformity involving the proximal femur. Conventional methods of treatment have been ineffective in controlling this problem. Two stage reconstruction was carried out in a case of polyostotic fibrous dysplasia with bilateral shepherd's crook deformity. Bilateral subtrochanteric osteotomies with intramedullary fixation in the first stage and intertrochanteric osteotomies in the second stage with nail plate fixation was done to provide definitive control of the deformity. Bone graft was not used.
