Abstract
This study was to analyze the minimum ten years clinical and radiological results of revision total hip arthroplasties using allogenic impaction bone graft and cemented cup in acetabular bone deficiency.
Fifty two revision total hip arthroplasties that had been performed in forty nine patients between March 1992 and June 1997 and had followed more than minimum ten years were included in this study. The clinical and radiological results were evaluated by Harris hip score and roentgenography including anterior-posterior view of pelvis and lateral view of operated hip.
The mean Harris hip score was 47 points preoperatively, 81 points at three years, 84 points at seven years, and 82 points at ten years after revision. In radiological evaluation, osseous union between grafted bone and host bone was seen within four months in 47 hips, a complete grafted bone-cement radiolucent line of two millimeter or more in at least one zone was seen in 5 hips at two years, 7 hips at seven years, and 2 hip at 10 years follow-up.
We recommend the technique using allogenic impaction bone graft and cemented cup to reconstruct the acetabular cavitary defect in revision total hip arthroplasties.
