当科における人工骨頭, 人工股関節の再置換術症例の検討

抄録

Ten revision operations of femoral endoprostheses and total hip arthroplasties were carried out in our clinic. Three endoprostheses were replaced with endoprostheses. Five endoprostheses were replaced with total hip arthroplasties. Two total hip arthroplasties were replaced with total hip arthroplasties. Four cases were caused by pyogenic infection one of which was a mycotic infection. Six other cases were caused by mechanical loosening or dislocation.
We classified these ten patients into infectious group and non-infectious group, and compared the two groups. We examined clinical and radiological findings after a mean follow-up period of 2.6 years (in infectious group) and of 7.3 years (in non-infectious group).
We considered that sufficient bone autograft and sufficient cementing are effective measures to guard against failure of revision surgery.
