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： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
