Abstract

The three-dimensional geometry of the inferior surface of the acromion was studied. The undersurface of the acromion was within a class of geometric surfaces known as `saddle' surfaces. Focussed contact was demonstrated by a leading edge of the acromion on the supraspinatus insertion where cuff tears generally originate. Broad contact was seen on rotator cuff areas which are rarely involved in cuff disease. Flattening the distal end of the acromion was insufficient in guaranteeing impingement elimination. The elimination of impingement after the anterior third flattening suggested the existence of a specific location on the acromion posterior to which bone removal produces no additional mechanical benefit.
