摘要:
目的:建立C5/6颈椎间盘的三维有限元模型并验证其有效性,探讨不同复合运动下颈椎间盘的生物力学变化。方法:建立C5/6椎间盘突出有限元模型,依次加载前屈+左旋转、前屈+右旋转、后伸+左旋转及后伸+右旋转复合运动,观察颈椎间盘突出区域的纤维环位移和髓核压力变化。结果:前屈+右旋转、后伸+右旋转时,椎间盘左后外侧突出区域的纤维环呈顺时针的旋前方向移动; 前屈+左旋转、后伸+左旋转时,椎间盘左后外侧突出区域的纤维环向逆时针的旋后方向移动; 前屈+左旋转、前屈+右旋转载荷下,椎间盘突出区域的纤维环位移值分别为-0.545 9 mm和0.676 5 mm; 后伸+左旋转、后伸+右旋转载荷下,突出区域的纤维环位移值分别为-0.663 1 mm和0.604 0 mm; 前屈+左旋转、前屈+右旋转载荷下,髓核的压力值分别为0.136 4 MPa和0.125 6 MPa; 后伸+左旋转、后伸+右旋转载荷下,髓核的压力值分别为0.193 7 MPa和0.147 8 MPa。结论:前屈向健侧旋转可有效缓解颈椎间盘突出患者的临床症状,而后伸向患侧旋转则可能会加重症状,不利于颈椎间盘突出患者的康复与治疗。
Abstract:
Objective:To establish the three-dimensional finite element model of C5/6 cervical intervertebral disc and verify its validity,and to explore the biomechanical changes of cervical intervertebral disc under different compound movement.Methods:The finite element model of C5/6 disc herniation was established.The flexion+left rotation,flexion+right rotation,extension+left rotation and extension+right rotation were loaded in turn to observe the displacement of annulus fibrosus and the change of nucleus pulposus pressure in the area of cervical disc herniation.Results:The annulus fibrosus in the left posterolateral herniated area of the intervertebral disc moved in a clockwise pronation direction under the loading of flexion+right rotation and extension+right rotation.The annulus fibrosus of the left posterolateral herniated area of the intervertebral disc moved counterclockwise under the loading of flexion+left rotation,extension+left rotation.The displacement of the annulus fibrosus in the disc herniation area was 0.545 9 mm and 0.676 5 mm under the loading of flexion+left rotation and flexion+right rotation,respectively.The displacement values of the annulus fibrosus in the protruding area were 0.663 1 mm and 0.604 0 mm under the loading of extension+left rotation and extension+right rotation,respectively.The pressure values of nucleus pulposus under flexion+left rotation and flexion+right rotation were 0.136 4 MPa and 0.125 6 MPa under the loading of flexion+left rotation and flexion+right rotation,respectively.The pressure values of nucleus pulposus were 0.193 7 MPa and 0.147 8 MPa under the load of extension+left rotation and extension+right rotation,respectively.Conclusion:Rotating forward flexion forward to the healthy side can effectively alleviate the clinical symptoms of patients with cervical disc herniation,and then extending to the affected side may aggravate the symptoms,which is not conducive to the rehabilitation and treatment of patients with cervical disc herniation.
