  • 본 연구에서는 가상 생체외 사체실험을 수행할 수 있는 경추 다관절 동역학 모델을 개발하였다. 평균크기 한국인 의료영상과 관절 및 연부조직의 물성 정보를 기반으로 하여 경추 동역학 모델을 개발하였다. 개발된 모델의 검증을 위하여 경추 단분절 및 다분절 모멘트-각도 관계, 인대 하중 및 후관절 접촉력 등을 문헌의 사체실험 결과와 비교한 결과 매우 유사한 경향을 확인하였다. 본 연구에서 개발된 경추 동역학 모델은 앞으로 경추 사체실험 연구 뿐만 아니라 자동차 충돌시 경추 상해 분석 등의 다양한 경추 생체역학 연구 연구에 활용될 수 있을 것이다.

  • Objective : Our purpose of this study is to compare insertion angles and screw lengths from Roy-Camille, Magerl, and our designed method for cervical lateral mass screw fixation in the Korean population by quantitative measurement of reformatted two dimensional (2D) computed tomography (CT) images. Methods : We selected thirty Korean patients who were evaluated with thin section CT scans and reconstruction program to obtain reformatted 2D-CT images of the transversal plane passing the cranio-caudal angle using three different techniques. We measured the minimum angle to avoid vertebral artery (VA) injury, the ideal angle and depth for bicortical screwing of cervical lateral mass. Morphometric measurements of the lateral masses from C3-C7 were also taken. Results : In all three techniques, the mean safety angles from the VA were less than 8 degrees and the necessary depth of the screw was about 14 mm for safety to the VA and for the bicortical purchase. In our designed technique, the mean $\beta$ angles of each level from C3 to C7 were 29.0. 29.8. 29.5. 26.3. and 23.9 degrees, respectively. Conclusion : Results of this study and data from the literature indicate that differences may exist between the Korean and Western people in the length and angle for ideal lateral mass screw fixation. In addition, our technique needs further cadaveric and clinical study for safety and efficacy for being performed as alternative method for cervical lateral mass fixation.
