In professional pitchers, distal UCL tears showed significantly higher odds of failure with nonoperative management compared with proximal tears. Thus, tear location should be considered when deciding between operative and nonoperative management.

Although uncommon, tears of the latissimus dorsi and teres major occur in professional baseball players. Acute injuries are demonstrated on standard shoulder MRI, although larger field-of-view images are required to accurately assess the injury. Most heal successfully with nonoperative treatment, and most players are able to return to the same level of competition in 3 months.

A strong relationship was found between lower degrees of dominant humeral torsion and more severe upper extremity injuries as well as a trend relating lower side-to-side differences in torsion with more severe dominant upper extremity injuries. In addition, there was a higher incidence of severe injuries in players with lower degrees of dominant torsion. If future studies confirm these results, humeral torsion measurements could play a role in risk assessment in pitchers.
