The elbow is second to the shoulder as the most common site of major joint dislocation. This injury pattern typically results from a fall on an outstretched hand when the elbow is hyperextended, and the forearm dislocates in a posterior lateral direction relative to the humerus. Acute management of elbow dislocation includes closed reduction and splinting in 90° of elbow flexion to maintain the reduction. The technique for closed reduction involves traction of the forearm, forearm supination, and elbow flexion. Simple dislocations without fracture usually have some degree of osteochondral injury, although surgical treatment is rarely necessary. Neurovascular injury is rare, but a detailed examination should be performed postreduction to rule out this complication. Recurrent instability after simple dislocation of the elbow is rare with an incidence of <1%.

Treatment for elbow dislocation includes a brief period of immobilization, usually 5 to 10 days, to relieve pain and swelling. Immobilization for >3 weeks is associated with chronic elbow stiffness and should be avoided. Early elbow motion can start 1 week after injury with the goal of slowly regaining full flexion and extension. Surgery is indicated when unstable fractures around the joint are identified or the elbow fails to stay reduced.1,2
