title: Comparative study of the closed reduction percutaneous  cannulated screw fixation and open reduction palmar locking  plate fixation in the treatment of AO type A2 distal radius  fractures.
abstract: BACKGROUND
  The present study was designed to demonstrate the efficacy of standard 4.0 mm cannulated screw fixation by comparing it with palmar locking plate fixation in the treatment of acute, unstable, simple extra-articular distal radius fractures.
  
  
  METHODS
  We prospectively collected and retrospectively analyzed outcomes data for 65 patients aged between 18 and 60 with AO type A2 fractures treated with closed reduction, percutaneous cannulated screw fixation (CRPCS n = 34) or open reduction palmar locking plate fixation (ORPLP n = 31). Range of motion, grip strength, Gartland-Werley and QuickDASH scores were compared at 2 months after surgery, and final follow-up (mean 32 months, range 12-90). Deterioration in radiographic parameters were measured and compared. Operative time and return to preinjury activity were evaluated.
  
  
  RESULTS
  Parameters did not differ significantly between the groups at either time point with respect to grip strength or range of motion, except pronation and supination; they were better in the CRPCS group (p = 0.005 and 0.025, respectively) at 2 month follow-up. The Gartland-Werley and QuickDASH scores obtained at final follow-up were similar for each group and lacked statistical significance. Group comparison for the deterioration of radiologic parameters showed no significant difference. CRPCS group had significantly shorter operative time (p = 0.001) and there was no significant differences between the groups regarding the return to preinjury activity (p = 0.129).
  
  
  CONCLUSIONS
  CRPCS group was found to be as successful as ORPLP group and it may be suitable in the case of young, active individuals with AO type A2 distal radius fractures.
