JCA = juvenile chronic arthritis, NR = not reported, JRA = juvenile rheumatoid arthritis, Perthes = Legg-Calvé-Perthes disease, PTA = posttraumatic arthritis, CD = congenital dysplasia, SOD = systemic onset disease, AS = ankylosing spondylitis, OA = osteoarthritis, TA = traumatic arthritis, DDH = developmental dislocation (dysplasia) of the hip, AVN = avascular necrosis, SD = spondyloepiphyseal dysplasia, PRC = pseudo rheumatoid chondrodysplasia, ON = osteonecrosis, OFH = osteonecrosis of femoral head, CIO = chemotherapy-induced osteonecrosis, SIO = steroid-induced osteonecrosis, and SCD = sickle cell disease. Note that some of the stated diagnoses (e.g., avascular necrosis and osteonecrosis) are equivalent.
Ruddlesdin et al. reported on twenty-nine of these cases in 1986.
