String theory. The supraspinatus tendon is presented as two strings representing the surface layer and the deep layer bundles of one surface. Rupture of both strings is a full-thickness tear; rupture of one of the two strings is a partial-thickness tear (superficial if the superficial string is torn and deep if the deep string is torn). An interstitial lesion is located between the two strings at the insertion. A cleavage is a gap between the two strings running between the tendon fibers.
