Abstract

Objective

We analyzed the influence of the location of the upper and lower cement on the sandwich vertebrae (SV) by computer finite element analysis.

Materials and Methods

A finite element model of the spinal segment of T11-L1 was constructed and 6 mL of cement was built into T11 and L1 simultaneously. According to the various distributions of bone cement at T11 and L1, the following four groups were formed: (i) Group B-B: bilateral bone cement reinforcement in both T11 and L1 vertebral bodies; (ii) Group L-B: left unilateral reinforcement in T11 and bilateral reinforcement in L1; (iii) Group L-R: unilateral cement reinforcement in both T11 and L1 (cross); (iv) Group L-L: unilateral cement reinforcement in both T11 and L1 (ipsilateral side). The maximum von Mises stress (VMS) and maximum displacement of the SV and intervertebral discs were compared and analyzed.

Results

The maximum VMS of T12 was in the order of size: group B-B < L-B < L-R < L-L. Group B-B showed the lowest maximum VMS values for T12: 19.13, 18.86, 25.17, 25.01, 19.24, and 20.08 MPa in six directions of load flexion, extension, left and right lateral bending, and left and right rotation, respectively, while group L-L was the largest VMS in each group, with the maximum VMS in six directions of 21.55, 21.54, 30.17, 28.33, 19.88, and 25.27 MPa, respectively.

Conclusion

Compared with the uneven distribution of bone cement in the upper and lower adjacent vertebrae (ULAV), the uniform distribution of bone cement in the ULAV reduced and uniformed the stress load on the SV and intervertebral disc. Theoretically, it can lead to the lowest incidence of sandwich vertebral fracture and the slowest rate of intervertebral disc degeneration.

骨质疏松症患者上下相邻椎体骨水泥分布对三明治椎体影响的静态研究和数值模拟:有限元分析
目的 通过计算机有限元分析,分析上下骨水泥位置对夹层椎体(SV)的影响。 材料与方法 建立 T11-L1 脊柱的有限元模型,在 T11 和 L1 中同时植入 6 mL 骨水泥。根据骨水泥在 T11 和 L1 的不同分布,分为以下四组:(i) B-B 组:T11 和 L1 椎体双侧骨水泥加固;(ii) L-B 组:T11 左侧单侧加固,L1 双侧加固;(iii) L-R 组:T11 和 L1 单侧骨水泥加固(交叉);(iv) L-L 组:T11 和 L1 单侧骨水泥加固(同侧)。对 SV 和椎间盘的最大 von Mises 应力(VMS)和最大位移进行了比较和分析。 结果 T12 的最大 VMS 依次为:B-B 组;L-B 组;L-R 组;L-L 组。B-B 组 T12 的最大 VMS 值最低,在负荷屈曲、伸展、左右侧弯、左右旋转六个方向的最大 VMS 值分别为 19.13、18.86、25.17、25.01、19.24 和 20.08 MPa,而 L-L 组是各组中 VMS 值最大的,六个方向的最大 VMS 值分别为 21.55、21.54、30.17、28.33、19.88 和 25.27 MPa。 结论 与骨水泥在上下相邻椎体(ULAV)的不均匀分布相比,骨水泥在 ULAV 的均匀分布降低并均匀了 SV 和椎间盘的应力负荷。从理论上讲,它可以使夹层椎体骨折的发生率最低,椎间盘退变的速度最慢。
