| Introduction |
 Very rare condition
- but has been reported as a cause of pain in the thrower’s shoulder
- Mechanism
- felt to be eccentric overload during the follow-through of the throwing motion
|
| Anatomy |
- Latissimus dorsi muscle
|
| Presentation |
- Physical exam
- local tenderness and deformity over latissimus dorsi muscles
- pain with shoulder adduction and internal rotation
|
| Imaging |
- MRI
- shows increased T2 signal and retraction of latissimus dorsi muscle
|
| Treatment |
- Nonoperative
- short period of rest followed by PT
- indications
- allow resumption of activities in low demand patients
- technique
- physical therapy goals are to restore shoulder motion and strength
- throwing can be allowed
- after full, pain-free motion and good strength
- balance of the rotator cuff and scapular rotator muscles
- Operative
- primary repair vs reconstruction
- indications
- for high demand athletes (currently there are no defined indications for surgical repair)
- technique
- early primary repair is favored to prevent retraction and scarring
