Background And Objective:
Anterior shoulder instability (ASI) is a common occurrence in the athletic population with specific management challenges in contact athletes due to the high activity demand and repetitive trauma during sport. This study aims to provide a narrative review of the current literature on ASI in contact athletes, with an emphasis on pathophysiology, mechanisms of injury, clinical presentation, diagnostic strategies, treatment options, including in-season management, and outcomes.
Methods:
A narrative review of the current literature on ASI in contact athletes was conducted, including key studies on the management and outcomes of conservative and surgical interventions.
Key Content And Findings:
ASI typically occurs from abduction and external rotation forces. Diagnosis relies on clinical assessment and imaging (magnetic resonance imaging or computed tomography), to evaluate soft tissue and bony injuries. Non-operative management is associated with high recurrence rates in contact athletes. Surgical options include arthroscopic Bankart repair (ABR) with or without remplissage, open Bankart repair (OBR), or bone block procedure such as Latarjet procedure or distal tibia allograft. All of which have been shown to decrease risk of recurrence and have a high rate of return to sport. The choice of procedure depends on the extent of soft tissue and bony involvement and the athlete's individual demands. ABR with glenoid bone loss >13.5% have high recurrence rates, therefore, additional procedures such as remplissage or bone block procedures should be considered.
Conclusions:
ASI in the contact athlete is a common and challenging injury to manage. Surgical intervention provides superior outcomes in terms of stability and recurrence prevention compared to non-operative management of ASI in the contact athlete. Patient-specific considerations including level of sport, patient goals, and timing of season are considerations for treatment. Labral injury with <13.5% of glenoid bone loss and on-track Hill-Sachs lesion ABR is recommended, labral injury with 13.5-20% of glenoid bone loss with off-track Hill-Sachs lesion ABR with remplissage or OBR with capsule shift is recommended, and if >20% then bone block procedure is recommended.
