101.00 MUSCULOSKELETAL SYSTEM
A. Rheumatoid arthritis . Documentation of the diagnosis of juvenile rheumatoid arthritis should be made according to an established protocol, such as that published by the Arthritis Foundation, Bulletin on the Rheumatic Diseases, Vol. 23, 1972-1973 Series, p. 712. Inflammatory signs include persistent pain, tenderness, erythema, swelling, and increased local temperature of a joint.
B. The measurements of joint motion are based on the technique for measurements described in the “Joint Method of Measuring and Recording,” published by the American Academy of Orthopedic Surgeons in 1965, or “The Extremities and Back” in “Guides to the Evaluation of Permanent Impairment,” Chicago, American Medical Association, 1971 Chapter 1, pp. 1-48.
C. Degenerative arthritis may be the end stage of many skeletal diseases and conditions, such as traumatic arthritis, collagen disorders, septic arthritis, congenital dislocation of the hip, aseptic necrosis of the hip, slipped capital femoral epiphyses, skeletal dysplasias, etc.
