Neer’s hypothesis that impingement caused most rotator cuff tears does not appear to have withstood the test of time, however. Arthroscopy and magnetic resonance imaging arthrography have elucidated many other conditions that cause shoulder pain that were previously misdiagnosed as impingement. Consequently, the liberal use of acromioplasty to treat “impingement” is being replaced by a trend toward making an anatomic diagnosis, such as a partial or complete tear of the rotator cuff, and performing aggressive rehabilitation prior to corrective surgery.
