It has already been pointed out, that the tendon quality is a very important factor regarding the outcome of rotator cuff reconstruction.[Chung SW et al.] Above all, in addition to the signs of tendinopathy, a delamination of the torn tendon should be highlighted. It is an additional negativ prognostic factor and complicates cuff repair. In delaminated tears the articular layer is usually retracted more than the bursal layer.[Bierry G et al.] Yet, imaging accuracy for determining the quality of a torn tendon is not known.

Delaminating tear of the supraspinatus tendon. This example is unusual for two reasons: The articular layer is retracted more than the bursal layer and the supraspinatus tendon is torn at the myotendinous junction.
