SITE OF MUSCULOSKELETAL INVOLVEMENT
The following subclassification to indicate the site of invo- lvement is provided for optional use with appropriate cate- gories in Chapter XIII. As local extensions or specialty adaptations may vary in the number of characters used, it is suggested that the supplementary site subclassification be placed in an identifiably separate position (e.g. in an additio- nal box.) Different subclassifications for use with derangement of knee, dorsopathies, and biomechanical lesions not elsewhere classified are given on pages 642, 649 and 677 respectively.
