Abstract

Despite the overall satisfactory results of total hip arthroplasty, post-operative complications continue to occur. To minimize these problems, computer-assisted total hip arthroplasty using navigation or robot-assisted systems is being developed. A navigation system is defined as a system that locates a position in three-dimensional space and traces the target spot, and a robot-assisted system is defined as a system that performs operations automatically with mechanical robot arms based on prior preoperative planning. Computer-assisted surgeries have shown superior results to conventional methods in implant positioning, fixation, and accurate lower extremity alignment in the limited reports available. However, computer-assisted surgeries take longer compared to conventional methods. Due to the extra time needed, the risk of postoperative infection and blood loss is considered to be higher. Nevertheless, robot-assisted system is being developed for the field of hip arthroplasty, and thus its efficacy and accuracy needs to be further investigated. Since these methods have other advantages compared to conventional methods, they are the focus of much interest.

인공 고관절 수술의 우수한 결과에도 불구하고 수술 후 합병증이 여전히 발생하고 있어 그러한 문제점들을 최소화하기 위해 컴퓨터를 이용한 정형외과 수술인 네비게이션 이용 수술 및 로봇 보조수술이 개발되었다. "네비게이션"이란 삼차원적인 공간에서 위치를 찾고 목표 지점을 추적하는 시스템이며 "로봇"은 사전에 저장한 명령에 기초하여 기계적인 로봇팔이 자동적으로 작업을 수행하는 것을 말한다. 컴퓨터 응용 수술은 이미 일부 보고에 의하면 고식적인 인공 고관절 수술과 비교할 때 더 우수한 인공 관절의 고정, 위치 및 하지정렬을 얻을 수 있다고 하지만, 고식적인 인공관절 수술보다는 추가 시간이 소요되므로 술 후 감염 및 실혈의 위험성을 고려해야만 한다. 로봇 보조 수술은 고관절 영역에서는 아직 시작 단계로 앞으로 효용가치와 정확성 여부가 연구되어야 할 것이다. 컴퓨터 응용 수술은 고식적인 수술에 비해 얻을 수 있는 장점도 있기 때문에 점점 관심이 증가하고 있는 분야이다.
