Methods : Vascularized heterotopic fibula was transplanted to the anterior-lateral part of the femoral neck. The fibula artery and vein were anastomosised with lateral circumflex artery and vein. Results : One hundred and twenty-nine cases of non-union femoral neck fracture were treated with vascularized fibula graft in our hospital from 1982 to 2002. Eighty-seven cases of them were followed up for 3 to 19 years with functional and X-ray examination. The percentage of fracture healing and effect were 94. 3 and 81. 6, respectively. Conclusion:The fibula with blood supply has a synergistic fixation impact on the non-union femoral neck fractures. The fibula is solid enough for supporting the femoral head and preventing it from collapse. The vascularized fibula grafting, by providing blood supply to the affected femoral head and neck, could promote the femoral head restoration and reconstruction. In addition, the periosteum of fibula plays a role in fracture healing.展开更多
