Editorial Commentary: Management of First-Time Anterior Shoulder Instability Requires Risk Stratification and Surgery...

The management of a patient with a first-time anterior shoulder dislocation has been the subject of longstanding debate among shoulder surgeons. A number of prognostic factors for recurrent instability have been proposed, including younger age, male sex, contact sports, and glenoid bone loss. Predictive tools and scores have been developed to assist in risk stratifying this patient population; however, no universally agreed upon, clinically validated algorithm exists. More recently, there has been emerging evidence favoring early surgical stabilization, as it has been shown to result in better overall outcomes compared with patients undergoing surgery following episodes of recurrent instability. With each subsequent dislocation or subluxation event, there is increased glenoid bone loss (and development of inverted-pear glenoid), a greater prevalence of engaging (i.e., off-track) Hill-Sachs lesions, more extensive labral tears, a greater risk of rotator cuff involvement (in the older patient), and increased plastic and/or permanent deformation, elongation, and compromise of the antero-inferior glenohumeral joint capsule and associated inferior glenohumeral ligament complex. Moreover, there is now sufficient evidence to suggest that recurrence comes at a cost, as it is a major risk factor for poor outcomes following arthroscopic stabilization. However, one risk is overtreatment, potentially exposing those individuals who would not have had another instability event due to an unnecessary procedure. We should continue to use the available evidence within the literature to help risk-stratify patients and develop an individualized treatment plan through a shared decision-making process with the patient.
