腰椎有限元模型的建立与不同角度牵引条件下的仿真研究
Establishment of a finite element model of lumbar spine and simulation under different traction angles
摘要
Abstract
Aim: To explore the effect of traction in different angles on lumbar discs traction in different angles . Methods:A three-dimensional finite element model of human lumbar segments L 1~5 ,and S1 was established based on med-ical CT images , and there were 148 943 nodes and 91 636 units in the model .Forces of two groups which size were respec-tively 320 and 200 N were exerted on the model based on clinical experience to simulate the traction under different traction angles such as 0°,5°,10°,15°,20°and 25°when the human body was lying down .Results:When the traction angle was 10°,the change of L4/5 was the largest,which was 2.42 mm;when the traction angle was 15°,the change of L3/4 was the lar-gest,which was 2.44 mm;when the traction angle was 20°,the change of L2/3 was the largest,which was 2.43 mm;When the traction angle was 25°,the change of L1/2 was the largest,which was 2.46 mm.Conclusion:The specific lesion of in-tervertebral discs can be better treated by adjusting the traction angle .关键词
