Effect of glenoid concavity loss on shoulder stability- a case report in a professional wrestler.

Background: Current glenoid defect measurement techniques only quantify bone loss in terms of defect diameter or surface. However, the glenoid depth plays an important role in shoulder stabilization by means of concavity compression.

Case Presentation: We present a case of a professional wrestler who suffered from anterior shoulder instability after sustaining a bony Bankart lesion without loss of glenoid surface area but flattening of the concavity due to medialization of the fragment.

Arthroscopic screw fixation of large anterior glenoid fractures.

Ten patients after traumatic shoulder dislocation with resulting instability due to an acute anterior glenoid fracture involving at least 21 percent of the glenoid length were treated by arthroscopic screw fixation of the fragment. The average fragment size measured 26.2% of the glenoid length.

Acromioclavicular reconstruction using autogenous semitendinosus tendon graft: results of revision surgery in chronic cases.

Revision surgery of acromioclavicular dislocation is challenging owing to the altered anatomic relationships and the lack of stabilizing structures. In this study, an autogenous semitendinosus tendon graft was used for revision acromioclavicular stabilization, aiming at anatomic coracoclavicular reconstruction, as these patients had previously undergone a Weaver-Dunn procedure, which failed. Twelve patients were followed up clinically and radiographically for a mean of 49.
