CEMENTLESS TOTAL HIP ARTHROPLASTY USING MORSELIZED BONE GRAFT IN PATIENTS WITH PROTRUSIO ACETABULI SECONDARY TO RHEUMATOID ARTHRITIS : CASE SERIES

Abstract

Rheumatoid arthritis (RA) is the most common inammatory joint disease lesions involving the hips, knees, and other large joints which can lead to joint deformity and dysfunction [1,2].Juvenile rheumatoid arthritis is chronic inammatory arthritis involving which may involve one or more joints with age of onset less than 16 years.With progressive hip disease, the deformed femoral head causes irregular abrasion of the acetabulum, secondarily shifting the femoral head inward and in turn triggering varying degrees of the acetabular protrusion, the incidence of which is about 5%.[3,4]THR in such cases provide improvement in function and pain but challenges posed by lack of bone stock, decient medial cup support, and medialization of the joint centre in those with protrusio acetabuli must be addressed during acetabular reconstruction.
