Inflammatory changes of the hip joint in rheumatoid arthritis often lead to secundary protrusio acetabuli. Total joint replacement may lead to problems, especially in mounting the acetabular component firmly to the pelvis. For about 7 years we have been using the so-called "active stabilisation of the acetabular floor" by implantation of autologeous bone prepared from the resected femoral neck. In changing the artificial joint homologeous bone from our bone bank was used. Up to Dec. 31, 1983 neither graft versus host reactions nor failure in healing were seen. 107 total joint replacements with bone transplantation in rheumatoid arthritis were performed. In all cases we could see optimal growing in of the transplanted bone, often confirmed by X-ray tomograms, with good support of the acetabular component. So far we have not seen any negative results. The active stabilisation of the acetabular floor seems to be a worthwhile addition to known surgical possibilities.
