Abstract:
The purpose of this study was to analyze the minimum two year clinical and radiological results of revision total hip arthroplasties using allogenic chip bone graft and cement in acetabular bone deficiencies. Thirty six revision total hip arthroplasties that had been performed in thirty four patients between Sep. 1992 and May. 1994 at Seoul Paik Hospital and had followed more than two years were included in this study. The clinical result was evaluated by Harris hip score. The mean Harris hip score was 48 points preoperatively, 88 points at final follow-up, a mean of 3 years after revision. In radiological evaluation, osseous union between grafted bone and host bone was seen within 4 months in thirty two hips (89%), a complete grafted bone-cement radiolucent line of two millimeter or more in at least one zone was seen in seven hips (19%) and acetabular component migration was seen in six hips (17%) at postoperative 3 year follow-up radiograph. At the time of follow-up, five hips (14%) had been revised a second time: three for aseptic acetabular loosening, two for infection. In conclusion, we recommend the technique using allogenic chip bone graft and cement to reconstruct the acetabular bone deficiencies in revision total hip arthroplasties, though other technique will be recommend in severe segmental acetabular deficiencies or previous infection.
