Metachronous bilateral subtrochanteric fracture of femur in an osteopetrotic bone: A case report with technical note.

Osteopetrosis is a rare inherited skeletal disorder characterized by increased density. The increased fragility of such dense bone results in a greater incidence of fractures, especially around hip and proximal femur. The surgical treatment of such fractures is difficult due to hard but brittle structure of bone. Herein we report a case of bilateral subtrochanteric fracture in an osteopetrotic patient. It was fixed using a dynamic hip screw with plate.
