title: Early weight-bearing after statically locked reamed intramedullary nailing of comminuted femoral fractures: is it a safe procedure?
abstract: BACKGROUND
  The purpose of this study was to determine the safety of early weight-bearing after statically locked reamed nailing of comminuted fractures of the femoral diaphysis, and to assess the rate of implant failure and fracture healing.
  
  
  METHODS
  Thirty consecutive patients with comminuted diaphyseal femur fractures (Winquist type II, III, and IV) were treated with statically locked reamed intramedullary nailing. Six patients were lost to follow-up, and the remaining 24 patients were followed at least 1 year. Early weight-bearing was allowed and encouraged in the first 2 weeks after the operation. The nail diameters were 13 mm in 16 patients, 12 mm in 6 patients, and 14 mm in 2 patients.
  
  
  RESULTS
  Most of the patients could start weight-bearing between the first 2 and 4 weeks postoperatively. None of the patients, except one, were using any walking aids at the second month postoperatively. All the fractures healed without any significant complications. Nail bending or breakage did not occur in any patients, but there was slight bending in one distal interlocking screw and one proximal interlocking screw. The fractures of the patients with bent screws healed uneventfully.
  
  
  CONCLUSIONS
  This study showed that early weight-bearing after reamed static interlocking nailing of Winquist type II, III, and IV femoral fractures is a safe and effective method, and the risk of implant failure does not preclude the procedure.
