Abstract:
[Objective]To explore the intermediate result of the use of allograft grafting for bone defects in revision total hip arthroplasty.[Methods]A retrospective study was carried out on 22 patients(22 hips) with the use of allograft grafting for bone defects in revision of total hip arthroplasty from April 2000 to April 2005.There were 13 male and 9 female with mean age of 65.5 years.According to the AAOS system,the bone defects in acetabulum were classified into type I in 5 hips,type II 14 hips and type III 3 hips,and on the femoral side,they were classified into type I in 3 hips,type II 12 hips and type III 2 hips.The reconstruction of bone defects in acetabulum contained structural bone graft in 5 hips,impaction bone graft in 12 hips,and metal wire mesh with bone graft in 5 hips.On the femoral side,3 hips were dealed with structural bone graft,12 hips were done with impaction bone graft,and 2 hips were repaired by metal wire mesh with bone graft.Harris Hip Score System and radiography were used to evaluate the clinical efficiency.[Results]The mean follow-up time was 61 months(37～97 months).Harris score improved from 45 points(30～65) pre-revision to 86 points(62～96) at the final follow-up.Insion drainage occurred in one hip.One patient remain slight pain in hip.No prothesis loosening,radiolucent lines were observed during the follow-up.None need to second revision.[Conclusion]During the THA revision surgery,adopting suitable allografts to repair the different types of bone defects is feasible and the mid-term result is good.
