中文摘要:
目的：分析不同牵引角度加载在颈椎曲度变直的模型上得到的数据，为临床牵引治疗颈椎病提供实验依据和临床建议。
方法：选取颈椎曲度变直患者采集CT数据（女性，43岁），采用专用生物力学有限元软件构建完整的颈椎全节段模型，包括使用实际解剖位置构建的颈椎韧带、肌肉组织；进行有限元模型的验证后，用0°、前屈5°、10°、15°、20°、25°进行牵引，观察椎间孔、关节突、钩锥关节、椎间盘的间距变化，以及髓核和基质的应力变化。
结果：当牵引角度为前屈0°～15°时，椎间孔、钩椎关节、后关节突之间的间距加大，椎间盘的拉应力适宜，压应力较小，比较符合临床治疗要求。
结论：建议牵引治疗颈椎病时采取前屈位0°～15°。 |

ABSTRACT
Objective: To analyze the data of angle variation on traction based on a finite element model of complete cervical spine with straight physiological curvature,and try to give experimental reference and suggestion in treating cervical spondylosis.
Methods: A 43-year-old female patient with straight cervical spine was chosen and the CT scan data were collected. By using specially designed modeling system,a high quality finite element model of complete cervical spine with straight physiological curvature is generated,which included ligament and muscle according to anatomy. After the model was confirmed,traction was loaded with angle 0°,anterior 5°,10°,15°,20°,25°,to observe the data of distance change on between adjacent intervertebral foramen,processus articularis,uncovertedral joint,intervertebral discs,and stress of anulus fibrosus and nucleus pulposus.
Results: When the angle was 0°-15°,the distance between intervertebral foramen,Luschka joint and processus articularis posterioris was enlarged,the tensile stress was adequate and compressive stress was small. It met the clinical requests.
Conclusion: 0°-15°anterior position is suggested for the treatment of cervical spondylosis. |
