脊柱跟随载荷在离体生物力学研究中的应用进展

Advances in Application of Spine Follower Loads in Biomechanical Studies in vitro

阐述跟随载荷在维持脊柱生物力学中的重要性,归纳近年来人离体脊柱标本跟随载荷模拟的各种方法及手段。通过与人体脊柱各椎体活动度、椎间盘内压等真实数据对比,从力学角度分析各类模拟手段的可行性,总结人体颈椎、胸椎、腰椎离体生物力学实验中最适合的加载载荷及扭矩,并探讨常规脊柱内固定术式对脊柱生物力学特性的影响。

The importance of follower loads in maintaining spine biomechanics was described,and the various methods and means of follower load simulations of human spine specimens in vitro in recent years were summarized.By comparison with the real data of range of motion(ROM)and intervertebral disc pressure of human vertebral body,the feasibility of various simulation methods was analyzed from the perspectives of mechanics,and the optimal loading load and torque of human cervical,thoracic and lumbar vertebrae biomechanical experiments were summarized.The effects of conventional spinal internal fixation on biomechanical properties of the spine were also discussed.
