Conclusion:
Injuries to the latissimus dorsi and teres major are increasingly
reported in baseball pitchers. However, in most countries, baseball is
an uncommon sport, and the diagnosis may be challenging because of
unfamiliarity with the injury among patients and health care providers.
Our case illustrates that classification of these injuries should be
clarified to avoid unnecessary surgical treatment recommendations.
Several centimeters of retraction of the latissimus dorsi part of the
conjoined tendon combined with a sub-total avulsion of the teres major
part as in the present case report may be successively treated
non-operatively with excellent functional results and return to the same
level of gymnastic performance in less than six months post-injury.
