Massive structural allograft in revision of septic hip arthroplasty

We reviewed 10 patients who had undergone two-stage reconstruction with massive structural allografts following failure of hip arthroplasty due to infection. The mean follow-up time was more than 5 years (range 3-10 years). There was no case of the infection recurring. The most common pathogen isolated at the time of first-stage surgery was Stalphylococcus epidermnidis. The mean preoperative modified Harris Hip score was 27.4 (range 9-58) and the mean postoperative score was 73.5 (range 53-92) with a mean increase in the score of 46.1 points. One patient required revision of the acetabular cup for aseptic loosening and another had a dislocation, which was stable after manual reduction. We conclude that the use of a massive structural allograft in revision of septic hip arthroplasty is a viable option.
