Glenohumeral arthrodesis

Abstract

Glenohumeral arthrodesis is a salvage procedure indicated for brachial plexus palsy, refractory instability, humeral and/or glenoid bone loss, deltoid and rotator cuff insufficiency, and chronic infections. The aim is to provide a painless, stable shoulder that is positioned to maximize function. Scapulothoracic motion as well as motion of the elbow and hand deliver satisfactory function in most patients. Intra-articular, extra-articular, and more commonly, combined techniques involving glenohumeral and humeroacromial fusion, have been described. More recently, authors have reported arthroscopic assisted techniques for shoulder arthrodesis with promising results as well as less complicated conversion from shoulder arthrodesis to reverse total shoulder arthroplasty. Despite advances in materials and techniques, glenohumeral arthrodesis continues to be associated with complication rates as high as 43%. A thorough understanding of the indications, contraindications, outcomes, and complications is paramount to improving patient results. Glenohumeral arthrodesis is a safe and effective procedure for the appropriate indications. The high frequency of complications mandates a frank preoperative discussion to ensure that each patient understands the magnitude of the procedure, its risks, possible complications, and expected outcome.
