Editorial Commentary: A Consensus of Experts Complements the Clinical Evidence on Diagnosis and Treatment of Anterior Glenohumeral Instability.

The current diagnostic and treatment strategies for anterior glenohumeral instability have been refined by high-quality clinical and basic science studies, but many controversies remain. These include the bone loss threshold for arthroscopic Bankart repair and the influence of other clinical factors on this decision, the optimal bracing position following anterior glenohumeral dislocation, and the optimal coracoid graft orientation during the Latarjet procedure. Randomized clinical trials often present conflicting results, and many of these are small-sample and fragile studies. Obtaining an expert consensus on the topic, by means of the Delphi method, is an attractive alternative to such clinical trials. Several studies employing variations of the Delphi method have addressed the diagnosis and treatment of anterior glenohumeral instability. These have stressed the importance of a meticulous technique during arthroscopic Bankart repair and of recognition of glenoid and humeral bone loss and treating this appropriately. These studies have also helped identify areas where consensus is modest or lacking to motivate additional clinical research study.
