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. RESULTS AND
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.
