摘要

本研究定量评估了腰椎融合与两种人工椎间盘假体对L2-L5的生物力学影响。建立正常/操作棘的有限元模型；模拟生理运动，记录运动范围（RoM）和相邻椎间盘的峰值von Mises应力。结果表明：熔合使相邻应力增大；机械假体提高了特定的RoM，粘弹性假体保持了接近正常的RoM/应力。椎间盘置换术具有更好的生物力学；粘弹性假体有助于生理保存，为腰椎退行性疾病的假体设计和临床实践提供参考。

Comparison of lumbar fusion and artificial disc replacement: a finite element analysis.

This study quantitatively evaluates biomechanical effects on L2-L5 of lumbar fusion versus two artificial disc prostheses. Finite element models of normal/operated spines were built; Physiological motions were simulated, with range of motion (RoM) and adjacent discs' peak von Mises stress recorded. Out results showed that fusion increased adjacent stress; mechanical prosthesis enhanced specific RoM, viscoelastic one preserved near-normal RoM/stress. Disc replacement has better biomechanics; viscoelastic prosthesis aids physiological preservation, informing prosthesis design and clinical practice for lumbar degenerative disease.

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.
