JF Annals of the Rheumatic Diseases JO Ann Rheum Dis FD BMJ Publishing Group Ltd and European League Against Rheumatism SP 122 OP 126 DO 10.1136/ard.35.2.122 VO 35 IS 2 A1 Byers, P D A1 Contepomi, C A A1 Farkas, T A YR 1976 UL http://ard.bmj.com/content/35/2/122.abstract AB Correlations between alterations in hip joints, described in a post-mortem study, have established the independence of limited and progressive alterations, and in addition have shown that there is a weak association between limited alterations and osteophytes and a strong one between progressive alterations and osteophytes. Nevertheless limited alterations may rarely undergo progressive damage. Cysts relate strongly to osteophytes but only moderately with progressive alterations. Limited alterations of both head and acetabulum can be subdivided. Some implications of these findings are discussed.
