Abstract
Significant anteroinferior glenoid bone loss is widely accepted as a major pathology of recurrent anterior shoulder dislocation, particularly after failed arthroscopic Bankart repair. Numerous surgical techniques for glenoid bone grafting have been described and have been reported to yield successful outcomes. Both open and arthroscopic approaches have been used, with the coracoid and the iliac crest being commonly used for bone graft. When compared with open surgery, an arthroscopic approach has many advantages. These include a smaller incision, better visualization, the ability to correct any concomitant pathology, and most important, preservation of the subscapularis muscle function. However, technical challenges and the steep learning curve of this complex arthroscopic procedure can be huge obstacles for shoulder arthroscopists. We describe, step by step, a simplified arthroscopic bone graft technique for repair of an anteroinferior glenoid defect using a template as a helpful tool.
