Abstract

Leg length discrepancies are a common cause of patient dissatisfaction after total hip arthroplasty (THA). The equalization of limb lengths and restoration of the anatomic geometry of the hip to restore normal gait and function are the primary goals during THA. Patients recognize a leg length discrepancy when one leg is shorter than the other by 6 mm or longer than the other by 10 mm after THA. Outside of this range, several problems would occur. Therefore, we should try to maintain leg length during THA via preoperative and intra-operative planning.

인공 고관절 전치환술을 시행함으로써 이환 된 다리의 길이를 복원시켜 주는 것은 고관절의 생역학을 복원시킨다는 점에서 환자의 수술 후 만족도를 높이는데 커다란 역할을 한다. 인공 고관절 전치환술 후 하지의 신장이 6 mm 이상, 단축 10 mm 이상이면 환자는 불편감을 느끼게 되고 그 이상의 차이가 생기게 되면 여러 가지 문제점 들이 발생하기 시작한다. 따라서 수술 전 또는 수술 중 철저한 계획과 정확한 술기로 하지 길이 변화의 차이를 최소화 시키고 가급적 원래의 하지 길이를 복원 할 수 있도록 노력하여야 한다.
