Reduction of the glenohumeral joint should be performed as an emergency procedure.
There are various techniques to reduce the glenohumeral joint.
Combined traction technique
Modified Stimson technique
Unless reduction is carried out very soon after dislocation, analgesia or anesthesia are typically necessary. An initial attempt with conscious sedation may succeed. If not, general anesthesia with complete muscle relaxation may be required. If closed reduction is unsuccessful, open reduction may be necessary.
