title: [Treatment of old femoral neck fracture with implantation of a vascularized fibular graft].
abstract: OBJECTIVE
  To investigate the healing of old femoral neck fracture treated with transplantation of vascularized fibula graft accompanied with lag screw, and rehabilitation of and precaution against ischemic necrosis of femoral head.
  
  
  METHODS
  Vascularized fibula autograft was transplanted to the anterolateral side of the femoral neck with an internal fixator of lag screw. Fibular artery and vein were anastomosed with lateral circumflex artery and vein.
  
  
  RESULTS
  186 of 229 cases subjected to systemic X-ray films and function follow-up (3 to 15 years). The percentage of fracture healing was 93.0% the sulass rate 86.5%.
  
  
  CONCLUSIONS
  Fibula with blood supply and compressed screw have a combined fixation effect of the old femoral neck fracture. Fibula is solid enough for supporting the femoral head and preventing it from collapse. Vascularized fibular grafting provides blood supply to the affected femoral head and neck, promoting femoral head restoration and reconstruction.
