摘要

腰椎后路椎体间融合术是一种对病变脊柱节段进行减压的常用技术。本研究旨在比较四种 PLIF 方案的生物力学效应。使用 L3-L4 节段的有限元模型模拟不同情况下的减压效果：S1（PEEK 骨架）、S2（带移植物的 PEEK 骨架）、S3（钛骨架）和 S4（带移植物的钛骨架）。在各种加载条件下测量了活动范围、应力和微动。S2 显示出足够的稳定性，减少了微动，降低了腰椎邻近部分的应力，表明 S2 可能是后路腰椎椎间融合术的首选。

A Comparative Biomechanical Analysis of Posterior Lumbar Interbody Fusion Constructs with Four Established Scenarios

Posterior lumbar interbody fusion is a common technique for decompressing the diseased spinal segment. This study aimed to compare the biomechanical effects of four PLIF scenarios. A finite element model of the L3-L4 segment was used to simulate decompression with different scenarios: S1 (PEEK cage), S2 (PEEK cage with graft), S3 (Titanium cage), and S4 (Titanium cage with graft). Range of motion, stress, and micromotion were measured under various loading conditions. S2 demonstrates sufficient stability, reduced micromotion, and lower stress on the adjacent parts of the lumbar segment, indicating that S2 may be a preferred option for posterior lumbar interbody fusion.

期刊介绍： The aim of the journal is to advance the research and practice in diverse areas of Multiscale Computational Science and Engineering. The journal will publish original papers and educational articles of general value to the field that will bridge the gap between modeling, simulation and design of products based on multiscale principles. The scope of the journal includes papers concerned with bridging of physical scales, ranging from the atomic level to full scale products and problems involving multiple physical processes interacting at multiple spatial and temporal scales. The emerging areas of computational nanotechnology and computational biotechnology and computational energy sciences are of particular interest to the journal. The journal is intended to be of interest and use to researchers and practitioners in academic, governmental and industrial communities.
