Which joint is listed as allowed to be reduced onsite?

• A. Glenohumeral joint
• B. Elbow
• C. AC joint
• D. Knee joint

Answer: (A)

On-site reduction is considered safe only for injuries that athletic personnel are trained to manage with a formal protocol, appropriate pain control, and a plan for imaging and follow-up care. The shoulder (glenohumeral joint) fits this scenario because anterior shoulder dislocations are common in sports, and there are well-established field reduction techniques that can provide rapid pain relief and allow quick immobilization before transferring the athlete for imaging and definitive care. The other joints listed involve higher risks and more complex injury patterns—elbow and knee dislocations can threaten blood flow and nerves and require careful imaging and medical evaluation, while AC joint injuries are typically immobilized and then referred rather than reduced on-site. Hence, the shoulder joint is the one allowed to be reduced onsite.
