Allogenous segmental fibular (strut) graft might be useful in the treatment of benign lesions in the proximal femur. It not only served as space filling function in addition to autogenous bone graft, but also provided an immediate mechanical strength in lesions sites. Between 1988 and 1991, thirty-five patients with proximal femoral lesions treated allogenous fibular strut inlay graft, supplemented with autogenous cancellous bone graft and transfixed with hip compression screw and plate fixation was retrospectively analyzed. The age of patients ranged from 18 to 54 years; sixteen were males and nineteen were females. The mean follow-up time was 3.5 years (ranged from 2 to 5 years). The diagnosis included 14 fibrous dysplasia, 11 simple bone cysts, 8 aneurysmal bone cysts and 2 giant cell tumors. Eleven patients (31%) suffered from pathologic fractures. All patients restored full weight bearing walking without limping gait within 6 months. From the serial radiographic evaluation, all cancellous graft was repaired within 6 months and strut graft need more than 2 years to achieve consolidation. There were no tumor recurrence, infection, avascular necrosis of femoral head or nonunion at the last follow-up. There are many factors to affect the repair of bone graft, the success of strut graft may warrant further clinical studies.
