title: [Treatment of acromion base fractures with double plates internal fixation].
abstract: OBJECTIVE
  To study clinical effects of double plates fixation for the treatment of acromion base fracutres.
  
  
  METHODS
  From January 2010 to May 2012, 7 patients with acromion base fractures were treated with double plates ORIF surgical treatment. There were 5 males and 2 females, with an average age of 36.3 years old (ranged, 24 to 62 years old). All fractures were acuted and closed injuries. The duration from injury to surgery was 4.6 days (ranged, 2 to 10 days). Hardegger functional criterion, Visual Analogue Scale (VAS) and complications of the patients were documented analysis.
  
  
  RESULTS
  All the patients were followed up,and the duration ranged from 4 to 13 months (averaged 8.9 months). The healing duration of fractures ranged from 8 to 14 weeks without any infection, shoulder instability, subacromial impingement syndrome, nonunion and failure of internal fixation. At the latest follow-up, the VAS ranged from 0 to 5. According to Hardegger criterion, 2 patients got an excellent result, 4 good and 1 poor.
  
  
  CONCLUSIONS
  Double plates ORIF plays a positive role in the treatment of acromion base fractures, which reduces complications and maximally restore the function of shoulder.
