Superior Labral Lesions

Lesions of the superior labrum have been associated with glenohumeral instability. Hinterman and Gachter noted that 7% of their patients with traumatic anterior instability requiring surgery had lesions of the superior labrum. Taylor and Arciero reported 10% of their patients had superior labral lesions associated with an initial anterior dislocation.

Pagnani et al.It showed in a cadaver study that superior labral lesions contributed to instability of the glenohumeral joint if the biceps attachment was destabilized.
