An elbow dislocation occurs when the bones of the forearm move out of place compared with the bone of the upper arm. The elbow joint, formed where these 3 bones meet, becomes dislocated, or out of joint. Specific, serious injuries that may occur are fractures, injuries to the arteries in the arm, and injuries to the nerves that run through the elbow area, impairing movement and feeling in the arm and hand.
Severe pain in the elbow, swelling, and inability to bend your arm are all signs of an elbow dislocation. In some cases, you may lose feeling in your hand or no longer have a pulse. Arteries and nerves run by your elbow, so it is possible you might have injured them during the dislocation.
X rays can be performed to find the dislocation of elbow. If the doctor suspects an injury to your artery, further tests, such as an arteriogram (an X-ray of your artery) may be performed.
