The authors indicated that we "used anatomical specimens to investigate the contact areas of the subacromial joint; however, the use of such specimens did not allow for direct clinical correlation." This statement is contrary to our findings and observations.

In 1981 and 1982, we studied sixty cadaveric shoulders and performed studies of the contact area between the rotator cuff and the inferior acromial surface. Multiplane radiographs were made of twelve acromions. Full-thickness tears of the rotator cuff were noted in eight of the sixty shoulders. In all eight shoulders, a corresponding area of osteophytes and osseous excrescences was observed on the anterior-inferior surface of the ipsilateral acromial process. In each instance, the pathological changes in the cuff corresponded to the stained contact area.
