Elbow dislocation causes, symptoms, and treatment
An elbow dislocation occurs when the upper arm and forearm get separated from their normal position. The bone of the upper arm (humerus) normally touches the bones of the forearm (the radius and ulna). When an elbow dislocation occurs, these bones are separated from their normal alignment. Elbow dislocations are the second most common joint dislocation, following shoulder dislocations.
