OBJECTIVE: To investigate the repairing result for the massive bony defects of upper and middle tibia and lower femur. METHODS: Since 1974, four types of pedicled-fibula transposition were performed to repair the massive bone defect of tibia and femur in 25 cases, which included; 9 cases with benign tumor of upper part of tibia were performed muscle-pedicled fibula transposition and knee fusion after tumor resection; 9 cases with extensive benign tumor or tumoroid lesion of tibia shaft were performed muscle-pedicled fibula transposition and tibia-fibula fusion after tumor resection; 2 cases with extensive benign tumor or tumoroid lesion of middle and lower parts of tibia were performed vascular pedicled fibula transposition and tibia-fibula fusion; 5 cases with benign tumor of distal femur were performed vascular pedicled fibula reversal transposition and knee fusion. RESULTS: After 3 months to 11 years follow-up, 23 cases showed bone healing at 6 months postoperatively. The other 2 cases showed bone healing at 12 months postoperatively. All cases had satisfactory functional rehabilitation. CONCLUSION: Pedicled-fibula transposition is a choice method for repairing massive defects of tibia and femur.
