Abstract:
Objective A two-stage renovation has nowadays been considered as the optimal mode for the treatment of infected total hip joint.Extensive bone defects were often found during the subsequent operation,and they should be repaired by using allograft to attain stability of the implants.The purpose of present study is to investigate the efficacy and safety of employing bone allograft in repairing the femoral defect caused by post-operation infection of hip arthroplasty in the second stage operation.Method From Mar.2001 to Dec. 2006,a total of 20 patients(20 hips)with infected total hip arthroplasty were treated with bone allograft on the femoral side in the second operation.Impaction bone grafting technique was performed for 16 patients using bone allograft combined with cemented stems,and un-ce- mented prosthesis combined with bone strut allograft were used in the other 4 cases.A regular follow-up was done and the outcomes were evaluated using the Harris Hip Score System and radiography.Result All patients were followed-up clinically and radiographically for an average of 20.3 months(4-61 months).No re-infection was found at the last time of follow-up.The mean Harris Hip Score was in- creased from 34.2 before operation to 87.7 after operation.90% of the patients were satisfactory with the results.Conclusion The bone allograft can be used for reconstructing bone defects in the patients after infection of total hip arthroplasty,either with combined with ce- mented stems or non-cemented stems.It is an effective and safe way in dealing with femoral bone defect after infection of total hip arthro- plasty.
