Objective To investigate the clinical effects of repairing massive bone defects in limbs by using vascularized free fibular autograft compoundingmassive bone allografts. Methods From January 2001 to December 2003, large bone defects in 19 patients (11 men and 8 women, aging from 6 to 35 years) were repaired by vascularized free fibular transplant with a monitoringflap compounding massive deep frozen bone allografts. The length of bone defects were 12 to 25 cm (16.6 cm on average), of vascularized free fibular 15 to 28 cm (18.3 cm on average), and of massive bone allografts 11 to 24 cm (16.1 cm on average). Thelocation of massive bone defects were humerus in 1 case, femur in 9 cases and tibia in 9 cases. Results After followup of 5 to 36 onths (18.2 months on average), wounds of donor and recipient sites were healed at Ⅰstage, monitoringflaps were alive, no obvious eject reaction of massive bone allografts was observed and no complications occurred in donor limbs. The radiographic evidence showed union in 15 patients 3 months and 3 patients 8 months after operation. One case of malignant synovioma of left lower femur recurred and amputation was performed 2.5 months after surgery. Internal fixation was removed in 5 patients, and complete bone unions werefound 1 year postoperatively. No massive bone allografts was absorbed or collapsed. Conclusion With strict indication, vascularized free fibular autograft compounding massive bone allografts, as an excellent method of repairing massive bone defects in limbs, can not only accelerate bone union but also activate and changer the final results of massive bone allografts from failure.
