Isolated traumatic rupture of the subscapularis tendon.
BACKGROUND
Although rotator cuff tears are well documented in the literature, there have been relatively few reported cases of isolated subscapularis tears. To our knowledge, no case has been reported that describes an isolated subscapularis tear in a woman without anterior shoulder dislocation or bony avulsion.


METHODS
This report outlines the case of a healthy 46-year-old woman with no history of shoulder problems who sustained injury to her right shoulder while hanging a light fixture. We highlight several key points to early diagnosis and underscore operative management for a successful outcome.


CONCLUSIONS
Isolated subscapularis tendon ruptures are uncommon in women. Increased vigilance during the history and physical examination is necessary to detect these injuries. Subscapularis tendon ruptures are commonly mistaken for degenerative rotator cuff tears or subacromial impingement syndrome. The lift-off test can isolate a subscapularis injury. Pertinent radiographic and magnetic resonance imaging findings are described.
