What is the initial reduction method for a posterior shoulder dislocation?

• A. Open reduction
• B. Closed reduction with sedation
• C. Observation
• D. No reduction

Answer: (B)

The first step in treating an acute posterior shoulder dislocation is a closed reduction performed under sedation or anesthesia. When the shoulder is displaced posteriorly, the surrounding muscles spasm and hold the head out of the socket. Relaxing those muscles with appropriate analgesia or general anesthesia makes a gentle, controlled realignment possible, increasing the chance of a successful, safe reduction without surgery. After realignment, immobilization and a structured rehab plan help restore stability and range of motion.

Open reduction is reserved for cases where closed reduction fails or there are associated fractures or soft-tissue injuries that prevent nonoperative realignment. Observation or doing nothing would leave the joint unreduced, risking ongoing dysfunction and complications like impingement or avascular issues.
