Fibrous dysplasia of the femoral neck is a serious clinical problem because structural stability is destroyed.We experienced treating four patients with monostotic fibrous dysplasia of the femoral neck. One of the patients was male and three were female, whose ages were 16 to 41 years. Two patients were treated with curettage of lesions of fibrous dysplasia and autogenous cancellous bone-grafting, together with vascular bundle transpla ntation. One patient was treated with curettage and cortical bone-grafting, and the other with corrective osteotomy for coxa vara after a pathological fracture.In the treatment of symptomatic fibrous dysplasia several surgical approaches have been uesd with varying success. Curettage and autogenous cancellous bone-grafting are used primarily as a means of filling small defects and inducing bone formation. But radical excision is being abandoned, since it is now recognized that removal of all dysplastic tissue is not needed to achieve a satisfactory result. So autogenous cortical bone is chosen for reconstructing large defects that require strength and is used primarily as supporting struts. When a symptomatic deformity is continued, corrective osteotomy is indicated to obtain normal biomechanical values of the hip.Our treatment plans are as follows;1) prevention of deformity and fracture2) corrective osteotomy for a symptomatic deformity
