<P> The angle is greater in the dominant limb than the non-dominant limb of both sexes, suggesting that natural forces acting on the elbow modify the carrying angle . Developmental, aging and possibly racial influences add further to the variability of this parameter . </P> <P> The types of disease most commonly seen at the elbow are due to injury . </P> <P> Two of the most common injuries at the elbow are overuse injuries: tennis elbow and golfer's elbow . Golfer's elbow involves the tendon of the common flexor origin which originates at the medial epicondyle of the humerus (the "inside" of the elbow). Tennis elbow is the equivalent injury, but at the common extensor origin (the lateral epicondyle of the humerus). </P> <P> There are three bones at the elbow joint, and any combination of these bones may be involved in a fracture of the elbow . Patients who are able to fully extend their arm at the elbow are unlikely to have a fracture (98% certainty) and an X-ray is not required as long as an olecranon fracture is ruled out . Acute fractures may not be easily visible on X-ray . </P>
