Traumatic First Time Shoulder Dislocation: Surgery vs Non-Operative Treatment.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Musculoskeletal Disorders

Background:

• Management of primary shoulder dislocations involves immobilization versus arthroscopic stabilization, with ongoing debate.
• Key considerations include the natural history of dislocation, surgical outcomes, and osteoarthritis (OA) risk.

Purpose of the Study:

• To review decision-making factors for managing first-time shoulder dislocations.
• To analyze the impact of surgical intervention versus non-operative management on recurrence and long-term OA.
• To evaluate the effects of delayed surgery and optimal immobilization techniques.

Main Methods:

• Extensive literature review focusing on four key areas: natural history, surgical effects, OA risk, and immobilization.
• Analysis of studies comparing operative and non-operative treatments for primary shoulder dislocations.

Main Results:

• Younger patients (<25 years) have a high re-dislocation rate with non-operative management.
• Surgery significantly reduces recurrent instability risk.
• Recurrent instability correlates with higher OA risk; surgical stabilization does not increase OA risk compared to single dislocations and is better than recurrent instability.

Conclusions:

• Delaying surgery increases complexity and potential for glenoid bone loss.
• External rotation braces have not consistently matched preliminary outcome expectations.
• Optimal treatment timing and type for shoulder dislocations should be individualized based on patient factors.
