The common cause for a dislocated elbow include Falls i.e. falling onto an outstretched hand which lead to out of alignment. Dislocations of the elbow fall in frequency just behind dislocations of the finger and shoulder. When a strong blow to the posterior aspect of a flexed elbow was given, it may result in an anterior dislocation of the elbow. This force drives the olecranon forward in relation to the humerus. Anterior dislocations and any open fracture are commonly associated with disruption of the brachial artery and/or injury to the median nerve.
Extreme pain and distortion of the joint, swelling, and inability to bend your arm are all signs of an elbow dislocation. In some cases, numbness in the hand regeion or no longer have a pulse (can't feel your heartbeat in your wrist) can also be observed. Arteries and nerves run by your elbow, so it is possible you might have injured them during the dislocation.
The physician tries to pull down the wrist in order to lever the joint into the right position. Placing a splint to keep the joint in a L shape is one of the treatment given. The purpose of placing a splint is to prevent movement of your arm at the elbow. Usually, your arm will be placed in a sling to help you hold up your splint. Of all elbow dislocations, 10-50% are sports related. More than 90% of elbow dislocations are posterior dislocations.
