In a joint dislocation, the bones of a joint become displaced, usually as a result of injury. A dislocation is often accompanied by tearing of the joint ligaments and damage to the membrane encasing the joint. There may also be damage to nearby nerves, tendons, and blood vessels.
Symptoms typically include severe pain in the affected area, deformity of the joint, and swelling and bruising around the joint.
Treatment usually involves manipulating the joint back into place, followed by immobilization in a splint or cast. In some cases, surgery to reposition the joint and repair any damage may be needed.
