Involvement of the proximal part of the femur by polyostotic fibrous
dysplasia is a progressive and disabling condition that leads to deformity.
Morbidity is high in terms of recurrent fracture and deformity.
Conventional methods of treatment have been ineffective in controlling
these problems. The cases of four patients were reviewed to determine the
natural history of polyostotic fibrous dysplasia involving the proximal
part of the femur. In six femora, multiple osteotomies with fixation using
a Zickel nail was utilized to provide definitive control of deformity and
recurrent fracture and to allow the patients to return to normal
activities.
