골시멘트를 사용한 Precoat 대퇴스템

초록

We now report the results of Harris Precoat femoral stem(Zimmer, Inc.,Warsaw,IN) of fourty hips in twenty-nine patients at a 5-7.5 year follow up.In this study, cemented precoat femoral stem was used in sixty-one, nonselected hip patients from October 1990 to May 1993 in our department. Twelve patients(13 hips) had been lost to follow up. At the final follow up, seven patients(7 hips) had died and one hips were too ill for detailed follow up. Radiographies were available for 36 hips of 26 patients who were alive for the entire follow up period. The average age at the time of the procedure was 54 years(range 27-76). There were twenty-three men(thirty-four hips) and six women(six hip). The femoral component had been revised for aseptic loosening in three hips(8%).One additional hip showed definite radiographic loosening. Hence, the prevalaence of radiographic failure was 11%(four hips). Three of them had suboptimal cement mantle(C1 or C2) Subsidence without radiolucency between cement interface occured in one hip. No femoral osteolysis was seen in stable component. These results show that cementation techinques is one of the most important factors for durability of cemented femoral stem, early debonding between stem-cement interface may develop even in this precoated femoral stem and also once debonding may produce premature failure of cemented femoral fixation.
