title: [Minimally invasive surgery to treat severe acromioclavicular dislocation combined with coracoid process fracture].
abstract: OBJECTIVE
  To discuss the diagnosis and minimally invasive surgical treatment on severe acromioclavicular dislocation combined with coracoid process fracture.
  
  
  METHODS
  Using 2 incisions of shoulder to expose and fix coracoid process and acromioclaricular joint and to repair damaged acromioclavicular ligament in 7 cases from March 1998 to March 2009.

  CONCLUSIONS
  Using 2 incisions of shoulder to expose and fix acromioclaricular joint and coracoid process with strong pertinence, reliable fixation and small tissue injury, which is a minimally invasive and effective method for severe acromioclavicular dislocation combined with coracoid process fracture.
