Anatomically, the carrying angle in human adults is approximately 10 degrees in men and 13 degrees in women. Increasing the carrying angle may lead to elbow instability and pain during exercise or in throwing activities of sports, may reduce function of elbow flexion, predispose to risk of elbow dislocation, and increase evidence of elbow fracture when falling on the outstretched hand and fracture of the distal humeral epiphysis.
