목적: 세라믹-세라믹 관절면을 가진 고관절 전치환술을 시행하고 그 단기 결과를 분석하고자 하였다. 대상 및 방법: 세라믹-세라믹 관절면을 가진 무시멘트 고관절 전치환술을 시행하였던 환자 중 2년 이상 추시 가능하였던142례를 대상으로 하였다. 평균 연령은 58.3세, 평균 추시 기간은 3.0년이었다. 평가는 Harris hip score와 서혜부및 대퇴 통증 및 방사선학적인 각종 지표를 이용하여 분석하였다. 결과: 평균 Harris hip score는 수술 전 58.1점에서 최종 추시 시 93.2점으로 상승하였고, 최종 추시 시 임상적으로유의한 통증은 4례(2.8%)에서 있었다. 추시 방사선 사진상 대퇴 삽입물은 전례에서 안정성을 유지하였다. 비구컵의 안정성은 2례(1.4%)에서 경사도가 유의하게 변화하여 해리로 진단되었다. 방사선 투과선은 대퇴측에서 9례(6.3%), 비구측에서 3례(2.1%)에서 보였으며, 골내막 신생골 형성은 대퇴측에서 50례(35%), 비구측에서 55례(38.5%)에서 각각관찰되었다. 골용해는 대퇴측과 비구측에서 모두 발생하지 않았다. 결론: 세라믹-세라믹 관절면을 이용한 무시멘트 고관절 전치환술의 단기 추시상에서 골용해 없이 우수한 결과를 얻을 수있었다
Abstract
Purpose: This study evaluated the short-term results of ceramic articulation total hip arthroplasty in cementless total hip arthroplasty. Materials and Methods: 142 hips were followed-up for more than 2 years after cementless total hip arthroplasty using ceramic-on-ceramic articulation. The mean age and follow-up period was 58.3 years and 3.0 years, respectively. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using various radiological indices. Results: At the last follow-up, the Harris hip score improved from 58.1 points preoperatively to 93.2 points postoperatively. There were 4 cases (2.8%) of significant hip pain. Radiologically, all the stems demonstrated stable fixation. The inclination of the acetabular cup was changed significantly in 2 cases (1.4%), which were diagnosed as being loosened. A radiolucent line was observed around the stem in 9 cases (6.3%), and around the cup in 3 (2.1%). Endosteal new bone formation was observed around the stem in 50 cases (35%), and around the cup in 55 (38.5%). No osteolysis was observed around the stem and the cup. Conclusion: The short-term results of ceramic on ceramic articulation hip arthroplasty were excellent without osteolysis.
