Fibrous dysplasia very commonly involves the proximal femur. Fibrous dysplasia of the proximal end of the femur is a serious clinical problem becaus structural stability is destroyed and function of the hip joint is impaired due to the
pathologic fracture and angulation deformity which influenced by biomechanical structure of the femur. So, the stability and functional reconstruction of the hip joint must considered at the treatment of the fibrous dysplasia of the
proximal
end of the femur. Authors have reviewed a series of 14 patients of fibreous dysplasia which were treated at the department of Orthopedic Surgery, School of Medicine, Kyung Hee University. The follow-up period ranged from January
1981
to
December 1990, the average being 3 years and 6 months. the average age was 21.8 years.
Among 14 patients, the nine patients were monostotic type showed bilateral involvement. The characteristics of the fibrous dysplasia around the hip joint were pain of the hip, coxa vara, angulation deformity, pathologic fracture of the
femur
was
not delayed. Ten patients(71%) revealed satisfactory result, and four patients marked unsatisfactory result by the Stephenson's classification. Simple curettage and bone graft couldnt' prevent the progression of deformity or
pathologic
fracture in widely expanded lesion. The prophylactic rigid internal fixation with massive bone graft was mandatory to prevent the progression of deformity or pathologic fracture.
