title: Comparison of retrograde intramedullary nailing and bridge plating in the treatment of extra-articular fractures of the distal femur.
abstract: OBJECTIVE
  The aim of this study was to compare retrograde intramedullary nailing (RIMN) and bridge plating for the treatment of extra-articular distal femur fractures.
  
  
  METHODS
  The study retrospectively examined 15 patients (13 males and 2 females; mean age: 36 years, range: 17 to 55 years) who underwent bridge plating and 13 patients (11 males and 2 females; mean age: 31.1 years, range: 17 to 49 years) who underwent RIMN for the treatment of extra-articular distal femur fractures between 2007 and 2012. Functional results were evaluated using the Sanders criteria. The mean follow-up time was 31.3 (range: 20 to 46) months and 26.7 (range: 18 to 62) months in the plate and the nail groups, respectively.
  
  
  RESULTS
  Mean duration until union was 25.7 (range: 12 to 72) weeks in the plate group and 22.3 (range: 12 to 52) weeks in the nail group. Nonunion was observed in 2 patients in the plate group and in 1 in the nail group, delayed union in 3 patients in the plate and 2 in the nail groups, malalignment (>10°) in 2 patients in the plate group and 1 in the nail group and implant failure in 1 patient in the plate group. Excellent/good functional results were obtained in 12 and 10 patients in the plate and the nail groups, respectively. No significant difference was found between the groups in terms of duration of union, complications and functional results (p>0.05).
  
  
  CONCLUSIONS
  Bridge plating and RIMN have similar results in the treatment of extra-articular distal femur fractures. Both methods can be applied to all fractures, with the exception of Gustilo-Anderson Type 3B and C open fractures.
