Bone grafting for acetabular protrusion in hip arthroplasty: 27 cases of rheumatoid arthritis followed for 2–8 years

Abstract
An acetabular bone graft with spongious bone chips was performed in 27 primary total hip arthroplasties in 23 patients with rheumatic disease. There were no major complications. After 5 (2–8) years, the grafts were well incorporated; after 1 year, remodeling had produced a normal cancellous bone structure. Clinical assessment showed overall good results.
