Proximal humeral fracture dislocations require prompt reduction of the glenohumeral joint dislocation.
Keep in mind that with fracture dislocations the need for conversion to an open reduction is highly likely. Preoperative plans should include this possibility.
Since the reduction of the dislocation may be difficult, regional or general anesthesia, including muscle relaxation, is recommended.
Note: Definitive operative treatment is usually best for glenohumeral fracture dislocations. Nonoperative treatment should be considered only if surgery has a significant risk, or if shoulder reduction has resulted in acceptable reduction of the fracture components.
