In-Season Management of Shoulder Instability: How to Evaluate, Treat, and Safely Return to Sport

Purpose of Review Anterior glenohumeral instability is a common injury in contact and collision athletes, and in-season management remains a controversial topic. Recent Findings Several recent studies have examined non-operative and operative management of in-season athletes after instability events. Non-operative treatment is associated with faster return to play and higher rates of recurrent instability. Dislocations and subluxations have similar rates of recurrent instability but non-operatively treated subluxations have a quicker return to play than dislocations. Operative treatment is often a season ending decision but is associated with high rates of return to sport and significantly lower rates of recurrent instability. Summary Indications for in-season operative intervention may include critical glenoid bone loss (>15%), an off-track Hill-Sachs lesion, an acutely reparable bony Bankart lesion, high-risk soft tissue injures such as a humeral avulsion of the glenohumeral ligament or displaced anterior labral periosteal sleeve avulsion, recurrent instability, insufficient time remaining in season to rehabilitate from injury, and inability to successfully return to sport with rehabilitation. It is the role of the team physician to appropriately educate athletes on risks and benefits of operative and non-operative treatment strategies and guide athletes through the shared decision-making process that balances these risks against their long-term health and athletic career goals.
