Anterior shoulder dislocation reduction: what patients should know

The clinician returns the upper-arm bone to the shoulder socket using a controlled manoeuvre, often after pain relief or sedation. Do not try to force the joint back yourself because this can injure nearby nerves, blood vessels, bone, or soft tissue.

In an anterior dislocation, the ball at the top of the upper-arm bone has moved forward out of its socket. Before reduction, the clinician examines the skin and checks the pulse, sensation, and muscle function in the affected arm. Imaging may be needed to identify an associated fracture and confirm the joint position.

During reduction, steady positioning and traction help the muscles relax while the joint is guided back into place. The shoulder is checked again afterwards, and follow-up imaging may confirm alignment. A sling supports the arm during the early recovery period.

Until help is available, keep the arm in the most comfortable position, support it against the body, and avoid food or drink in case sedation is required. Remove rings or a watch if swelling develops, but do not repeatedly test shoulder movement.

After reduction, follow the prescribed sling and pain-relief plan. Move the fingers, wrist, and elbow as advised. Rehabilitation usually progresses from protected movement to strength and shoulder-control work; returning too quickly to lifting or sport can provoke another dislocation.

Seek emergency care for a visibly deformed shoulder after injury, severe pain, an open wound, or inability to move the arm. A hand that becomes cold, pale, blue, increasingly numb, or weak may signal nerve or circulation compromise and needs immediate assessment.

Return promptly after reduction if the shoulder slips out again, pain or swelling is worsening, fever develops, or new tingling or weakness appears. Persistent looseness after recovery can reflect shoulder instability and warrants specialist review.

Ask whether a fracture or tendon injury was seen, how long to use the sling, when to begin guided movement, and what activities to avoid. If this has happened before, discuss whether further imaging, structured physiotherapy, or an opinion about stabilisation surgery is appropriate.
