title: Arthroscopic treatment of glenoid bone loss.
abstract: Recurrent anterior instability of the glenohumeral joint has long been an arduous problem to solve surgically, owing to its difficulty to the need to restore both osseous and dynamic constraints in the unstable shoulder. Biomechanical studies have indicated that glenoid bone loss shortens the safe arc through which the glenoid can resist axial forces; in these cases, a soft tissue repair alone may be insufficient to maintain stability. Clinical studies have confirmed that major bone loss is associated with an unfavourable outcome. The benefits of using arthroscopic procedures for surgical stabilization of the shoulder include smaller incisions and less soft tissue dissection, better access for repair and, potentially, the maximum respect for the undamaged anatomical structures. The biggest disadvantage of arthroscopic procedures until recently was the inability to successfully treat a significant bone defect. Over the last 10 years, several new arthroscopic techniques have been developed, providing new surgical options for successfully treating soft tissues and bony lesions in anterior-inferior glenohumeral instability. Level of evidence V.
