Gerber reply:We thank Drs. Bhatia, deBeer, and du Toit for their interest in our
article. They remarked that humeral head medialization in patients with
massive cuff tears can influence the "acromion index" and
suggested that a large lateral extension of the acromion therefore may be
relative rather than absolute and that its association with rotator cuff tears
may be a consequence rather than a cause.
