시멘트형 대퇴 스템을 사용한 인공 고관절 재치환술의 결과 = Results of Revision Hip Arthroplasty using Cemented Femoral Stem

다국어 초록 (Multilingual Abstract)

Purpose: To analyze clinical and radiological follow-up results of patients who underwent revision hip arthroplasty with a cemented stem. Materials and Methods: This study reviewed the records of 31 patients (34 hips), who underwent revision hip arthroplasty with a cemented stem between February, 1993 and May, 2004 after an average follow-up of eight years. There were 14 segmental type hips according to the femoral bone defect using the AAOS classification. According to the Paprosky classification, there were 7 and 5 type IIC and type III hips indicating a severe bone defect. Immediate postoperative cement mantle grades were grades A and B(26 hips) and grade C, D(8 hips). Results: The Kaplan Meier survival rate of the cemented stem was 80.7% at 8 years. Re-revision hip arthroplasty was performed in 5 hips, in whom aseptic loosening occurred 4 hips, and infection occurred 1 hip, which was cured by re-surgery. Immediately after the operation, 4 out of the 5 re-revision cases were classified as C & D in the Barrack classification of the cement mantle. Overall, an inadequate cement mantle led to a poorer survival rate. Conclusion: The results of revision hip arthroplasty using a cemented stem were not so good. However, the cemented stem might be used in cases considered unsuitable for a cementless stem if a good cement mantle could be achieved using a skillful cement technique.
