The purpose of this paper is to describe a new surgical procedure for the treatment of protrusio acetabuli of patients suffering from rheumatoid arthritis. Bone grafts are used to reinforce the medial acetabular wall, and to correct the position of the head of a bipolar hip prosthesis. The advantage of this procedure is that it does not require bone cementing over the grafted bone.
This procedure has been carried out for 16 hips of 15 patients. No migration nor loosening has been observed, and all the hips have become functional.
