Abstract

We performed total hip arthroplasty using the non-cement impaction auto-bone-grafting method with the resected femoral head for acetabular protrusion that is not combined with the destruction of acetabular rim or dysplasia of the hip joint. Ten patients (eight women and two men) with rheumatoid arthritis who showed acetabular protrusion underwent total hip arthroplasty using this method. All patients were able to walk with full weight within 5 days after surgery. The short-term results of our cases were very good. The postoperative periods of the radiographic-bone incorporation of the grafting bone were 2 months after surgery in four joints, 3 months after surgery in four joints, and 4 months after surgery in three joints. There were no cases that showed any migration or radiolucency around the acetabular component at the time of follow-up. Our operative technique is simple and easy, and it is a useful method for the treatment of protrusion in patients with rheumatoid arthritis.
