title: [One stage revision of infected total hip replacements with replacement of bone loss by allografts. Study of 90 cases of which 46 used bone allografts].
abstract: We usually manage infected total hip replacements by a one stage revision. We have reviewed 90 cases operated on before 1988. Notable bone loss was frequently encountered and reconstructed using allografts. In all cases complete surgical debridement was performed and a cemented total hip replacement implanted. Bone allografts were used in 46 cases. Systemic antibiotics and antibiotic loaded cement were utilised. There were 17 failures (19%); one patient died soon after operation, there were 8 obvious infections (9%), 1 hip was thought to be infected although the prosthesis was not loose, and 7 femoral prostheses became loose of which 3 were due to mechanical failure and the remainder had no obvious explanation. Infection with staphylococcus aureus and pseudomonas had a statistical correlation with failure, but other factors including the preoperative status and the use of allografts did not appear to influence the result. Allograft femoral heads from the bone bank were found to be reliable for reconstruction of the acetabulum and small femoral defects. With major femoral bone loss we preferred massive irradiated cortical allografts. The quality of the bone reconstruction was probably the most important factor in the good functional results observed in 79% of cases. Effective surgical debridement and an appropriate antibiotic regime will allow a successful one stage revision procedure. The use of allografts gave a reliable reconstruction of the bone loss and was not associated with an increased rate of failure.
