dc.description.abstractPurpose:전방십자인대 재건술시 흔히 관찰하게 되는 Resident’s ridge의 실제 형태학적 위치 및 모양을 알아보고자 한다.



Material and Methods : 2007년 1월부터 2007년 8월까지 본원에서 시행한 48례의 정상 대퇴골 원위부를 촬영한 MD CT (Multidetector-Row Computed Tomography) 영상을 분석하였다. 과간절흔의 외측벽에서 1 mm 이상의 높이 변화를 보이는 경우를 Resident’s ridge로 정의 하였다. Lucion. 프로그램을 이용하여 3차원 재구성한 영상을 통해 과간절흔의 전후방 길이, resident’s ridge의 길이, 높이, 과간절흔의 후방 피질골로부터의 거리를 측정하였다.



Results: 환자의 평균 연령은 59±16세였으며 남성이 16례, 여성이 32례 이었다. Resident’s ridge가 존재 하지 않았던 경우는 9례 이었으며 과간 절흔의 전후방 길이는 25.4±3.5 mm, Resident’s ridge 의 길이와 높이의 평균값은 각각 8.2±2.6, 3.5±1.5 mm 이었으며 Resident’s ridge의 후방 피질골로부터의 거리는 7.6±2.6 mm 이었다.



Conclusion:Resident’s ridge는 많은 예에서 존재하며 뚜렷한 길이와 높이가 있기 때문에 전방십자인대 재건술시 주요한 landmark로 사용할 수 있다.

dc.description.abstractPurpose: The purpose of this study was to report the real geometry of Resident’s ridge doing in anterior cruciate ligament reconstruction.



Material and Methods : From Jan 2007 to Aug 2007, 48 cases which had normal distal femoral condyle analyzed with Multidetector-Row Computed Tomography. Resident’s ridge was defined as change of height above 1 mm in lateral wall of intercondylar notch. Anterior-posterior length of intercondylar notch, length and height of Resident’s ridge, distance of Resident’s ridge from posterior cortex were estimated with 3-D reconstruction using Lucion. program.



Results: Cases were 59±16 years olds and male was 16 cases, female was 32 cases. 9 cases had no Resident’s ridge, anterior-posterior length of intercondylar notch was 25.4±3.5 mm, average of length and height of the Resident’s ridge was 8.2±2.6, 3.5±1.5 mm. Distance of the Resident’s ridge from posterior cortex was 7.6 ±2.6 mm.



Conclusion: Resident’s ridge was used as landmark in anterior cruciate ligament reconstruction, which presented in many cases and which had distinct length and height.
