title: Comparative results of percutaneous cannulated screws, dynamic compression type plate and screw for the treatment of femoral neck fractures.
abstract: BACKGROUND
  The purpose of this study was to compare the period of union, functional outcomes and complications of patients with femoral neck fracture treated with percutaneous cannulated screws versus dynamic hip screw (DHS).
  
  
  METHODS
  Sixty-six patients with femoral neck fracture were treated with percutaneous cannulated screws (n=33) or with DHS (n=33) between August 1999 and October 2003. Functional outcome was measured using Harris Hip Score, and period of union, amount of bleeding and complications were also recorded.
  
  
  RESULTS
  The period of union and functional outcomes were not different between the two groups. Risk of avascular necrosis (AVN) was associated mainly with the grade of fracture displacement. In the percutaneous cannulated screw group, duration of surgery was shorter and blood loss was less than in the other group.
  
  
  CONCLUSIONS
  There was no superiority between cannulated screws and DHS according to union times and functional results. Risk of AVN is related to the degree of displacement. However, a prospective randomized study is needed to determine the outcome of each technique for patients suffering similar displacement rates.
