[Femoral neck fracture in a patient with osteopetrosis].

Osteopetrosis is a rare hereditary bone disease characterized by increased bone density. Patients with adult osteopetrosis are often diagnosed incidentally by X-ray or on the presence of recurrent fractures. Internal fixations of fractures in patients with osteopetrosis are challenging due to the increased bone density, and special surgical equipment is often necessary. Non-union and malunion occur frequently making close post-operative monitoring important. We present a case of adult osteopetrosis with a femoral neck fracture.
