Abstract
We evaluated acetabular reconstruction with an impacted bone graft and an F-S cup supporter in cemented revision THR. 19 patients (21 hips) were reviewed clinically and radiographically at an average of 3.5 years (range, 1 to 9.5). According to the classification of acetabular deficiencies proposed by the A. A. O. S., 5 hips were Type II (cavitary), and 16 hips were Type III (segmented and cavitary). Acetabular defieciency was filled with a 5-10mm morcelized autograft and allograft chips, and impacted with trial head prosthesis. Then, an F-S cup supporter and a socket were placed with cement following a two-stage procedure. There was no definite radiographic evidence of the acetabular loosening according to the system of Murloys study. The average JOA hip score was 45.8 points preoperatively and 72.8 points at final review. Despite the shourt-term follow-up, we consider that the results of acetabular reconstruction with impacted bone graft and F-S cup supporter were satisfactory.
