Between 1991 and 2002, we performed 156 primary total hip replacements in rheumatoid arthritis patients with protrusion acetabulum. The deficient acetabulum was reconstructed with autologous and allogous morsellized bone grafts from the femoral head.
Group 1 were 26 patients with reconstruction acetabulum deficient with autologous morsellized bone grafts and group 2 were 10 patients in witch we use allogous grafts. All patients were reviewed at an average follow-up of 5 years. The function of operated hips was determining according WOMAC, HHS and Merle-d'Aubigne-Postela scores. Incorporation of grafts was assessing according to Avci criteria.
We found similarly good and very good results in both groups. Incorporation of allo- and auto- bone grafts was observed after average 26 months. In 1 hip we found porotic grafts but without of loosening of the acetabular component.
This technique is a good option in cases with protrusion acetabulum due to rheumatoid arthritis.
