Threaded Acetabular Cup은 과연 모두 문제가 있는가? -CLW threade cup의 5년 이상 추시 결과-
이중명 ( Joong Myung Lee ),조덕연 ( Duck Yun Cho ),나기호 ( Ki Ho Nah ),이중배 ( Joong Bae Lee ) 대한고관절학회 1995 Hip and Pelvis Vol.7 No.2
We reviewed 14 patients(22 hips) to whom had been performed total hip arthroplasty using CLW(CementLess weill, Protek, Switzerland)acetabular cup at the department of orthopaedic surgery, National Medical Center from February 1988 to August 1990. The purpose of this retrospective follow-up study was to analyze the radiological findings such as loosening or migration at the acetabular component and to assess the usefulness of the CLW cup. The CLW acetabular cup is made of self-tapping, double-threaded anchoring ring with deep pitch and low profile and it is made of pure titanium with rough corundum blasted surface. The average age of the patients at operation was 49 year(23-62 years) and all were male. The mean follow-up period was 6years and 3months(from Syears 2months to 7years 9months). The operation had been performed by a single surgeon(J-M Lee) using transgluteal approach. We analyzed the loosening and migration on the immediate postoperative and last follow-up plain X-ray film by Engh's criteria, which demonstrated no loosening and migration. While we need long term follow-up, we think that threaded cups which are well designed biomechanically and have good surface with bone on-growth capability should make different results compared to the poor results of other threaded cups.

CLS expansion cup의 이론적 개념과 3년 이상 추시 결과
이영구,최장석,김영창,안기찬,김용훈 인제대학교 1998 仁濟醫學 Vol.19 No.1
나사형 컵들은 초기 고정은 좋으나, 시간이 지나면서 무균성 이완에 따른 축성 이동(axial migration)을 하여, 심하면 골반내 비구 돌출(acetabular protrusion)을 야기하는 문제점이 있어서 사용이 중단되었다. 본원에서 사용하였던 CLS expansion cup은 방사선학적으로 특별한 문제점들을 발견할 수 없었기 때문에 객관적으로 방사선학적 계측으로 분석하여 문헌 고찰과 함께 그 장기 추시 결과를 보고 한다. We reviewed 19 patients(22 hips) to whom total hip arthroplasty was applied using CLS (Protek, Switzerland) acetabular cup at the department of Orthopaedic Surgery, Pusan Paik Hopital from 1992 to 1993. The purpose of this retrospective follow-up study was to analyze the radiographic findings such as loosening or migration at the acetabular component and to assess the usefulness of the CLS expansion cup. The CLS expansion cup is made of titanium alloy. The average age of the patients at operation was 56 year(47-67 years)and 16 were male and 3 were female. The mean follow-up period was 3 years and 7 months. The operation was performed by a single surgeon (Y-C Kim) using Watson-Johnson lat approach. We analyzed the loosening and migration on the immdiate postoperative and last follow-up plain X-ray film by Engh's criteria, which demonstrated neither loosening nor migration. It is believed that threaded cups which are well designed biomechanically and have good surface with bone on-growth capability should make different results compared to the results of other threaded cups.
