Treatment of Anterior Shoulder Instability: A Comprehensive Review
Anterior shoulder instability is a complex spectrum of pathology characterized by excessive translation of the humeral head across the glenoid, leading to apprehension, subluxation, and dislocation. Diagnosis and classification require a thorough clinical history, physical examination, and imaging to appropriately determine the severity of instability. Depending on the individual patient anatomy and severity of instability, there exist many management options that are well-positioned to successfully treat this pathology and allow patients to return to prior functional levels. Treatment options available are conservative management, arthroscopic or open Bankart repair, remplissage, open or arthroscopic Latarjet, and glenoid bone grafting. Each of these options provides unique advantages for the surgeon in treating a subset of patients along the spectrum of disease. Selection of treatment modality depends upon the number of instability events, appropriate quantification, classification bone loss, presence of associated soft tissue injuries, and patient-specific goals regarding return of function. The purpose of this review was to present an evidence-based approach to the investigation, treatment selection, and follow-up of anterior shoulder instability. Individualized patient care is required to optimally address intra-articular pathology, restore stability and function, and preserve joint health for all.
