Abstract

PURPOSE
To evaluate the radiological and clinical results of cementation of a polyethylene liner into a well-fixed metal shell in revision total hip arthroplasty.
MATERIALS AND METHODS
From November 2001 to April 2006, 11 cases (10 patients) were included in this study. There were 5 males (6 cases) and 5 females with a mean age of 54.3 years. The mean follow-up period was 35.2 months. The acetabular shells were stable and their position was acceptable in all cases. Pre-existing screws were removed and screw holes were filled with allogenic bone. The inner surface of the metal shells and convex backside of the liners were roughened with a burr. The clinical results were evaluated using the Harris hip score (HHS) and the radiological results with evidence of a positional change in the acetabular cup and liner, and the progression of osteolysis around the cup.
RESULTS
The mean HHS was 69.5 points preoperatively and 89.2 at the last follow up. There was no change in the cup and liner position or progression of the osteolytic lesion around the femoral or acetabular components.
CONCLUSION
Cementation of a polyethylene liner into a well-fixed metal shell showed satisfactory results in revisional total hip arthroplasty with a short term follow-up period.
