title: [Clinical study on traumatic anterior instability of shoulder].
abstract: OBJECTIVE
  To study the clinical diagnosis, conservative and surgical treatment of traumatic anterior instability of the shoulder.
  
  
  METHODS
  Based on the experience in diagnosis and treatment of 41 patients, we put forward criteria for diagnosis and treatment of traumatic anterior instability of the shoulder.
  
  
  RESULTS
  Diagnostic criteria: (1) history of injury to the shoulder; (2) sharp pain in the anterior aspect of the shoulder and weakness and limitation of range of motion of the shoulder; (3) the positive apprehension sign and or anterior drawer test; (4) a Hill-Sachs bony lesion on roentgenogram and abnormal double contrast CT.
  
  
  METHODS
  (1) rehabilitation program for the patients having symptoms less than 3 months and without anterior capsular rupture; (2) capsular repair and imbrication procedure for the patients having symptoms more than 3 months, or not satisfied to the rehabilitation treatment, or severe anterior capsular rupture on double contrast CT. The results of the treatment were satisfactory with average 16-month follow-up.
  
  
  CONCLUSIONS
  The diagnostic criteria and the treatment principles help improve the results of treatment of shoulder injuries, further clinical study is needed for traumatic anterior instability of the shoulder.
