Approach to Latissimus Dorsi and Teres Minor Injuries in the Baseball Pitcher

Tears of the latissimus dorsi and teres major are uncommon but significant injuries, most frequently seen in high-level, overhead throwing athletes. Diagnosis can be challenging, as there are no pathognomonic signs, symptoms, or physical exam findings associated with latissimus dorsi/teres major tears, and the clinician must have a high suspicion for this injury. While many of these tears can be treated non-operatively, a subset of these benefits from surgical intervention. Rehabilitation following operative and non-operative treatments of these injuries is extensive, and timing of return to sport can be variable from 3 to 12 months.

The literature surrounding latissimus dorsi/teres major injuries is sparse. Several small studies have shown good results in patients with mild to moderate tears that were treated non-operatively. Recent evidence has shown good results following operative repair of larger tears, with excellent return to sport rates. Furthermore, focused rehabilitation is imperative when treating patients with latissimus dorsi/teres major injuries to allow these athletes to return to sport. Latissimus dorsi/teres major tears are uncommon but significant injuries in the throwing athlete. Prompt diagnosis, proper treatment, and focused rehabilitation will allow these patients to return to sport in a safe and efficient manner.
