3 ( ) Site of musculoskeletal involvement 列 ( ) 類 類 數 不 類 () 類 ( ) 力 不 類 692~ The following subclassification to indicate the site of involvement is provided for optional use with appropriate categories 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 additional box.) Different subclassifications for use with derangement of knee, dorsopathies, and biomechanical lesions not elsewhere classified are given on pages 692~693, 700 and 728 respectively. 0 0 Multiple sites 1 () 1 Shoulder region clavicle acromioclavicular scapula glenohumeral joints sternoclavicular 2 2 Upper arm humerus elbow joint 3 3 Forearm radius wrist joint ulna 4 4 Hand carpus joints between these bones fingers metacarpus 5 5 Pelvic region and thigh () buttock hip (joint) () femur sacroiliac joint pelvis 6 6 Lower leg fibula knee joint tibia 7 7 Ankle and foot metatarsus ankle joint tarsus other joints in foot toes 679

Distinction is made between the following types of etiological relationship: (a) direct infection of joint, where organisms invade synovial tissue and microbial antigen is present in the joint; (b) indirect infection, which may be of two types: a reactive arthropathy, where microbial infection of the body is established but neither organisms nor antigens can be identified in the joint, and a postinfective arthropathy, where microbial antigen is present but recovery of an organism is inconstant and evidence of local multiplication is lacking.
