The influence of the intervertebral disc on stress distribution of the thoracolumbar vertebrae under destructive load

Objective: To compare the influence of normal and degenerative discs on stress distribution of the thoracolumbar vertebrae under destructive load, explore the biomechanical background and clinical meaning and provide theoretical basis for clinical diagnosis and treatment. Methods: A mechanical model of thoracolumbar motion segment of normal and degenerative discs was built with a three dimensional finite element method and three stresses of vertical compression, compressive flexion and distractive flexion were comparatively analyzed. Results: With vertical compression and compressive flexion loads, the thoracolumbar motion segment of the normal disc showed that the central part of the upper and lower end plates of the vertebrae and the central part of the trabecular bone adjacent to the end plate were loaded with the most intensive stresses, meanwhile, the postero lateral part of the annulus fibrosus was concentrated with stresses. Degenerative disc showed that the stress distribution of the trabecular bone was relatively averaged, the stresses of the central part adjacent to the end plate were low, while at the same time, the stresses of the peripheral part were elevated relatively. With distraction flexion load, the stresses of the cortex bone, trabecular bone, end plate and annulus fibrosus of the thoracolumbar vertebrae of degenerative discs were low, meanwhile, the stresses of the posterior structure of the vertebral body were relatively elevated compared with that of normal discs. Conclusions: There is difference in influence between normal and degenerative discs on the stress distribution of the thoracolumbar vertebrae with destructive load. The transferring way of load is changed after disc degeneration.

Comparison of biomechanical effect between oblique Ban-pulling manipulation and lumbar erection-rotation manipulation in sitting position for lumbar intervertebral disc herniation

Objective： To compare the biomechanical effects between oblique Ban-pulling manipulation and lumbar erection-rotation manipulation in sitting position in treating lumbar intervertebral disc herniation （LIDH）. Methods： A three-dimensional finite element model of L3-S1 was developed to carry out a comparative study between oblique Ban-pulling manipulation and lumbar erection and rotation manipulation in sitting position. The disc protrusion was assumed to be on the rear left of L4 disc, and the manipulations were performed on the right side. The loading process was simulated by two steps, in the first step, only the compression loading was imposed, and in the second step, both the compression loading and axial rotation moment were imposed. The displacement and stress distribution in L4 disc were investigated. Results： The values of stress and displacement in the second step were lower than those in the first step in each manipulation. The stress and displacement differences between the two steps were respectively 1.79 times and 3.03 times larger in oblique Ban-pulling manipulation than those in lumbar erection-rotation manipulation in sitting position. Conclusion： Oblique Ban-pulling manipulation may result in a better biomechanical effect than lumbar erection-rotation manipulation in sitting position for LIDH.

The cure rate after one course of treatment was significantly higher in the treatment group than in the control group （P〈0.05）. Conclusion： Abdomen acupuncture has a good effect on lumbar intervertebral disc protrusion with a short course of treatment.

经椎间孔入路经皮内窥镜下椎间盘切除术后类脊髓高压综合征伴代谢性酸中毒1例报告并文献复习

腰椎椎间盘突出症(LDH)是骨科常见病,其病因复杂,主要与遗传、椎间盘退行性变、发育异常、腰部外伤、姿势不当等因素相关^([1])。其发生率呈增长趋势,并呈年轻化,给患者个人、家庭和社会带来了巨大的经济和医疗负担,严重影响患者日常生活及工作^([2])。约85%的LDH患者伴有坐骨神经痛^([3]),部分患者甚至出现二便失禁^([4])。LDH首选药物、物理治疗等非手术治疗方式,但非手术治疗疗效不佳的情况下需考虑手术治疗。

腰椎立体定位斜扳法与传统腰椎斜扳法对椎间盘及关节突关节软骨影响的有限元分析

目的:分析腰椎立体定位斜扳法与传统腰椎斜扳法对椎间盘及关节突关节软骨的影响。方法:选取1例成年男性L_(4-5)椎间盘突出症患者(椎间盘向左后方突出),采用西门子Light Speed 64排螺旋CT进行腰椎和骨盆扫描,层厚0.5 mm。基于CT扫描数据,应用三维有限元建模软件建立腰椎-骨盆三维有限元模型,通过与文献数据比较验证模型有效性后,分析腰椎立体定位斜扳法与传统腰椎斜扳法作用下腰椎-骨盆整体应力、L_(4-5)椎间盘应力和位移、L_(4-5)关节突关节软骨应力和位移、L_(4-5)上下关节突表面中心点相对空间距离。结果:①腰椎-骨盆三维有限元模型建立及验证结果。建立的腰椎-骨盆三维有限元模型共有550215个节点、344359个单元,高度模拟了腰椎-骨盆的结构与材料特性。在模拟加载条件下,L_(4-5)节段屈伸、侧屈、轴向旋转活动范围与文献中的既往研究结果基本相同。②模型整体应力。实施传统腰椎斜扳法时,腰椎-骨盆三维有限元模型最大应力为5.31 MPa,主要集中于L_(1)、L_(2)、L_(4)、L_(5)椎体;实施腰椎立体定位斜扳法时,腰椎-骨盆三维有限元模型最大应力为29.30 MPa,主要集中于L_(1)、L_(2)椎体及L_(3)、L_(4)、L_(5)椎弓根。③L_(4-5)椎间盘应力及位移。实施传统腰椎斜扳法时,L_(4-5)椎间盘纤维环平均等效应力为1.12 MPa,纤维环整体向左、向前、向下发生位移,平均位移分别为0.36 mm、0.20 mm、0.05 mm;髓核平均等效应力为0.02 MPa,髓核整体向左、向前、向下发生位移,平均位移分别为0.35 mm、0.24 mm、0.06 mm。实施腰椎立体定位斜扳法时,L_(4-5)椎间盘纤维环平均等效应力为1.14 MPa,纤维环整体向左、向前、向下发生位移,平均位移分别为0.39 mm、1.30 mm、0.05 mm;髓核平均等效应力为0.02 MPa,髓核整体向左、向前、向下发生位移,平均位移分别为0.38 mm、1.30 mm、0.07 mm。④L_(4-5)关节突关节软骨应力及位移。实施传统腰椎斜扳法时,L_(4-5)左侧和右侧关节突关节软骨平均等效应力分别为2.46 MPa、3.18 MPa,平均位移分别为1.10 mm、0.21 mm;实施腰椎立体定位斜扳法时,L_(4-5)左侧和右侧关节突关节软骨平均等效应力分别为2.70 MPa、3.22 MPa,平均位移分别为1.46 mm、0.65 mm。⑤L_(4-5)上下关节突表面中心点相对空间距离。实施传统腰椎斜扳法时,L_(4-5)左、右侧上下关节突表面中心点相对空间距离分别为0.75 mm、0.34 mm;实施腰椎立体定位斜扳法时,L_(4-5)左、右侧上下关节突表面中心点相对空间距离分别为0.81 mm、0.23 mm。结论:腰椎立体定位斜扳法与传统腰椎斜扳法均能使腰椎间盘突出症患者病变节段椎间盘及关节突关节软骨产生一定的应力和位移;相较于传统腰椎斜扳法,腰椎立体定位斜扳法能使病变节段椎间盘和关节突关节软骨产生更大的应力和位移,这也可能是腰椎立体定位斜扳法比传统腰椎斜扳法治疗腰椎间盘突出症疗效更佳的原因。
