Abstract

Objective: To compare biomechanical effects of full-endoscopic laminectomy (Endo-LOVE) versus continuous-endoscopic technique (C-Endo LFD) in normal and osteoporotic cervical spines. Methods: Four C2-C7 finite element models simulated daily activities: normal/osteoporotic bone density treated with Endo-LOVE or C-Endo LFD. Range of motion (ROM), endplate/facet joint stress, and disc pressure (IDP) were quantified. Results: Both techniques showed comparable biomechanical effects. Osteoporotic models demonstrated greater ROM increases (18.3% vs normal), elevated facet joint stress (24.6% increase), and higher endplate stress (22.1% increase). IDP remained unchanged between groups. Conclusion: C-Endo LFD does not increase cervical instability risk. However, in osteoporosis it elevates surgical segment ROM and joint/endplate stresses, potentially affecting postoperative stability.

Endo-LOVE和C-endo LFD技术治疗正常和骨质疏松双节段神经根型颈椎病的比较生物力学分析：一项有限元研究

目的：比较全内窥镜椎板切除术（Endo-LOVE）与连续内窥镜技术（C-Endo LFD）在正常和骨质疏松症颈椎中的生物力学效果。方法：4个C2-C7有限元模型模拟日常活动：正常/骨质疏松骨密度，endolove或C-Endo LFD处理。对活动范围（ROM）、终板/关节突关节应力和椎间盘压力（IDP）进行量化。结果：两种技术表现出相当的生物力学效果。骨质疏松模型显示更大的ROM增加（比正常增加18.3%），小关节关节应力增加（增加24.6%），终板应力增加（增加22.1%）。国内流离失所者在各组之间保持不变。结论：C-Endo LFD不增加颈椎不稳风险。然而，在骨质疏松症中，它会增加手术节段ROM和关节/终板应力，潜在地影响术后稳定性。

期刊介绍： The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
