Histologic characteristics of the subscapularis tendon from muscle to bone: reference to subscapularis lesions.

Background: Although subscapularis tendon lesions seem to differ from those of the supraspinatus tendon, the features they have in common suggest that the subscapularis tendon may also have 2 distinct layers. Our aim was therefore to characterize the histologic structure of the subscapularis tendon from its humeral insertion point to the musculotendinous junction.

Material And Methods: A histologic study was performed on 10 autopsy samples.
