BACKGROUND: The use of a cemented cup together with an uncemented stem in @entity572 ( @entity572 ) has become popular in Norway and Sweden during the last decade. The results of this prosthetic concept, reverse hybrid @entity572 have been sparsely described.We report our experience of reverse hybrid @entity572 , using the Elite plus @entity691 cemented cup together with the Corail fully @entity692 -coated uncemented stem and a 28-mm alumina ceramic head. @entity1 AND METHODS: 132 consecutive reverse hybrid hip arthroplasties were performed from January 2000 to December 2003 in 126 @entity1 with a mean age of 54.3 years (28-65). All @entity1 were routinely reviewed at 3 months, 1, 5, 7 and 10 years postoperatively. At each follow-up @entity1 were seen either by a consultant orthopaedic surgeon or a senior trainee. Anteroposterior pelvic and lateral x- @entity16039 of the hip were taken at each visit. To estimate the survival of the THAs we used the Kaplan-Meier method with 95% confidence interval (CI). Logistic regression analysis was performed to determine which factors affected the presence of radiolucency around the femoral stem. RESULTS: The mean follow-up was 11.1 years (9.0-14.2). 1 @entity1 was lost to follow-up, and 7 @entity1 were deceased at the time of 10-year follow up. At 10 years 7 @entity1 have had further surgery. 5 for infection, 1 periprosthetic femoral fracture and 1 heterotopic bone formation. All stems were classified as well fixed. 2 cups were defined as loose at 10 years. 1 @entity1 is scheduled for revision the other refused revision. The clinical outcome and radiological findings were assessed in 123 hips. The mean Harris Hip Score was 94 (35-100) at 10 years and the mean WOMAC score was 89 (30.2-100). CONCLUSIONS: We report good results with respect to clinical outcome and survival of the reverse hybrid concept in @entity1 younger than 65. A successful outcome depends on meticulous preoperative planning, use of modern cementing techniques in the acetabulum and experience in implanting an uncemented stem.
