title: Does Subacromial Osteolysis Affect Shoulder Function after Clavicle Hook Plating?
abstract: OBJECTIVE
  To evaluate whether subacromial osteolysis, one of the major complications of the clavicle hook plate procedure, affects shoulder function.
  
  
  METHODS
  We had performed a retrospective study of 72 patients diagnosed with a Neer II lateral clavicle fracture or Degree-III acromioclavicular joint dislocation in our hospital from July 2012 to December 2013. All these patients had undergone surgery with clavicle hook plate and were divided into two groups based on the occurrence of subacromial osteolysis. By using the Constant-Murley at the first follow-up visit after plates removal, we evaluated patients' shoulder function to judge if it has been affected by subacromial osteolysis.
  
  
  RESULTS
  We have analyzed clinical data for these 72 patients, which shows that there is no significant difference between group A (39 patients) and group B (33 patients) in age, gender, injury types or side, and shoulder function (the Constant-Murley scores are 93.38 ± 3.56 versus 94.24 ± 3.60, P > 0.05).
  
  
  CONCLUSIONS
  The occurrence of subacromial osteolysis is not rare, and also it does not significantly affect shoulder function.
