Radiology of athletic injuries: baseball.

The radiographs and medical records of 29 professional basebell players from several teams were reviewed. Each player had been selected because of radiographic abnormalities. Abduction views of the shoulder were employed in pitchers and outfielders who complained of shoulder pain. Upper extremity abnormalities predominated and accounted for 22 injuries including avulsion injuries of the origin of the long head of the triceps at the infraglenoid tubercle of the scapula and traction injuries at the origin of the pronator muscles at the medial epicondyle of the humerus. Trauma to the lower extremities was caused by collision with a fixed barrier in one man and by running and sliding in 13 others.
