Acetabular supporting ring in total hip replacement.
A series of 14 total hip arthroplasties with a Müller acetabular supporting ring including 3 primary and 11 revision arthroplasties is reviewed. This device was used in cases of acetabular bone deficiency, and bone graft was added in 11 cases. The mean length of follow-up was 39.9 months. Twelve patients had good or satisfactory results, while two operations failed. These results indicate that the acetabular supporting ring is a useful implant in cases with acetabular bone stock deficiency.
