This study examined the minimum seven years clinical and radiological results of revision total hip arthroplasty using an allogenic impaction bone graft and a cemented cup in an acetabular bone deficiency.

Fifty two revision total hip arthroplasty procedures performed on forty nine patients between March 1992 and June 1998 and followed for more than minimum seven years were examined. 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 after revision, and 84 points at seven years. The radiological evaluation revealed osseous union that trabeculated between grafted bone and host bone within four months in 47 hips, a complete grafted bone-cement radiolucent line of two millimeters or more in at least one zone in 5 hips at two years and in 7 hips at the seven year follow-up.

We recommend the technique using an allogenic impaction bone graft and cemented cup to reconstruct an acetabular cavitary defect in revision total hip arthroplasty.
