title: Acceptable parameters for alignment of distal radius fracture with conservative treatment in elderly patients.
abstract: BACKGROUND
  There is a conflict in the treatment of distal radius fractures in elderly patients, because fracture reduction does not appear to be as strongly associated with functional outcomes as in younger patients. The purpose of this study was to evaluate radiographic findings of acceptable reduction without leading to wrist dysfunction and poor outcomes.
  
  
  METHODS
  Fifty-two active and healthy elderly patients with conservatively managed distal radius fractures were included in the study. They consisted of 7 men and 45 women, all 60 years or older. Radiographic assessment included volar tilt, radial inclination and ulnar variance, and outcome evaluation included the Mayo wrist score and DASH score. As a control group, the preoperative radiographic and clinical outcomes were examined as well for 19 patients older than 60 with malunion, for whom corrective osteotomy was performed because of wrist dysfunction. The radiographic parameters and clinical outcomes were compared between the two groups in a statistical manner. Correlation coefficients of the radiographic parameters with Mayo wrist score and DASH score were analyzed by multiple regression.
  
  
  RESULTS
  Volar tilt (mean -1.2°) and ulnar variance (mean 2.5 mm), as well as Mayo wrist score (mean 80.0 points) and DASH score (mean 8.6 points) in the objective group were significantly superior to those in the control group when comparing radiographic parameters and clinical outcomes. There was no significant difference between the two groups in regard to RI (mean 14.9°). Multiple regression analysis revealed that volar tilt and ulnar variance were significantly correlated with the clinical outcomes in the objective.
  
  
  CONCLUSIONS
  The parameters of volar tilt and ulnar variance had a significant correlation with clinical outcomes. Clinical outcomes significantly worsened when those parameters exceeded a tolerable range. In elderly patients, it is important to determine an appropriate therapeutic modality for a distal radius fracture when considering the acceptable parameters for alignment.
