Fibrous dysplasia of the femoral neck. Treatment by cortical bone-grafting.

Fibrous dysplasia of the femoral neck is difficult to treat. In a series of fifteen young patients, ten had a monostotic lesion and five, the polyostotic form of the disease. Twelve patients were first seen with a fatigue fracture. Grafts of cortical bone were used. The objectives of relief of pain, union of the fracture, and prevention of deformity were achieved in all fifteen patients. Two patients required a repeat procedure. None of the patients had important deformity of the femoral neck, and none needed an osteotomy.
