To the Editor.—
In the article by Morris et al,1 the authors describe the Injury Severity Score and the methods of calculating it. They divided the body into seven regions (head and face, neck, chest, spine, abdomen and pelvic contents, extremities and pelvic girdle, and integument). However, in the 1985 revision of the abbreviated injury scale, published by the American Association for Automotive Medicine, the body is divided into six areas (head or neck, face, chest, abdominal or pelvic contents, extremities or pelvic girdle, and external). Morris et al have increased the number of body areas scored by adding spine. Has the 1985 edition of the abbreviated injury scale been altered by them or by the American Association for Automotive Medicine?
