Abstract:
[Objective]To explore the efficacy and result of femoral component revision by using impaction bone grafting technique with anatomic cemented stem and freeze-dried allograft.[Method]Anatomic cemented stem combined with freeze-dried allograft were used in IBG for 49 cases of femoral revisions from Jan,2001 to Dec 2005.36 cases(73%)of which had severe bone loss(Paprosky grades ⅢB and Ⅳ).The mean follow-up time was 35.3 months(26~52 months).Harris Hip Score System and radiography were used to evaluate the clinical results.[Result]The mean Harris Hip Score was improved from 44.6 points preoperatively to 88.3 points at final evaluation.Good and excellent scores were about 89.8%.No major femoral stem subsidence was found in our patients.There were one case of dislocation(2%),one case of deep infection(2%)and 3 cases of femoral fractures during operations(6.1%),which were not related to the selection of femoral component and the type of allograft.[Conclusion]The impaction bone grafting technique by using freeze-dried allograft and the anatomic cemented femoral prosthesis for femoral revision was feasible and the short and mid-term result was good.Longer follow-up was needed to evaluate the long term result.
