Impaction bone grafting法を用いた人工骨頭再置換術の経験

抄録

Herein is reported the results of revision endoprosthesis with an Exeter stem, using impaction cancellous allografts and cement. One male and two females underwent primary endoprosthesis with cement at other hospitals, using non-Exeter stems to correct the fracture of the neck of the femur. The mean age at the time of primary intervention was 74.0 years (ranging from 70 to 84 years). At the mean 8 year-follow-up period (ranging 1 to 13 years) after the first operation, loosening of the primary endoprosthesis occured with severe pain and revision surgeries with Exeter stems were performed by the first author, using impaction bone grafting technique. In all three hips reviewed at the mean follow-up period of 13 months after revision surgery, there were no complications and satisfactory results with evidence of graft incorporation were observed.
