Abstract
Artificial disc replacement (ADR) is a clinical procedure used to diagnose cervical degenerative disc disease, preserving range of motion (ROM) at the fixation level and preventing adjacent segment degeneration (ASD). This study analyzed the biomechanics of ADR by examining range of motion (ROM), stress levels in bone and implants, and strain in the bone-implant interface using multi-scale loadings. The study focused on single- and double-level patients across various loading scales during physiological motions within the cervical spine. Results showed increased ROM in single-level and double-level fixations during physiological loadings, while ROM decreased at the adjacent level of fixation with the intact cervical spine model. The Prodisc-Implant metal endplate experienced a maximum von Mises stress of 432 MPa during axial rotation, confirming the long durability and biomechanical performance of the bone-implant interface.
人工椎间盘置换术（ADR）是一种用于诊断颈椎间盘退行性病变的临床手术，可保持固定水平的活动范围（ROM）并防止邻近节段退变（ASD）。本研究分析了 ADR 的生物力学，使用多尺度加载法检测了活动范围 (ROM)、骨和植入物的应力水平以及骨-植入物界面的应变。研究重点是单层和双层患者在颈椎生理运动过程中的各种加载尺度。结果表明，在生理负荷期间，单层和双层固定的 ROM 均有所增加，而在完整颈椎模型中，相邻固定层的 ROM 则有所减少。Prodisc-Implant 金属内板在轴向旋转时的最大 von Mises 应力为 432 兆帕，证实了骨-植入物界面的长期耐用性和生物力学性能。
