Abstract:
[Objective]To evaluated the clinical results of treatment of osteoneerosis of the femoral head(ONFH)with repair and reconstruction through long-term follow-up.[Methods]A total of 313 patients(382 hips)operated on from November 1986-March 1997 who had a mean age of 36.4 years(range,18～65 years)were reviewed retrospectively.The hips were 151 Ficat and Arlet stage Ⅱ,142 stage Ⅲ,89 stage Ⅳ.All patients were followed up for a mean of 12.1yrs(range,10～20 yrs) and were assessed clinically and radiologically according to Harris scoring and variation of Ficat stage respectively.The patients were analyzed by the Kaplan-Meier method with replacement for any reason as the end-point.[Results]Ninteen hips underwent total hip replacement postoperatively.Preoperative and postoperative Harris score were 56.2 and 85.8.Clinical success rate was 85.6%and radiological success rate was 75.4%.Kaplan-Meier survivorship curves showed there was a lower long-term survival on stage-IV、abuse of hormone alcolutic indulger and above 55 years old patients.[Conclusion]The long-term efficacy is satisfactory to be confirmed by repair and reconstruction in treatment of osteonecrosis of the femoral head.This procedure will improve the curative effect of preserving head treatment of ONFH and early-middle clinical results being satisfied.
