对象
进行了一项体外生物力学研究，以确定前稳定对多节段人类尸体腰椎模型中融合器辅助腰椎椎间融合生物力学的影响。
方法
比较了三种脊柱条件：采集、双侧多节段椎间融合器（CAGES）和椎间融合器与生物可吸收前路钢板（CBAP），在屈伸、侧弯和轴向旋转条件下进行测试。测量包括椎体运动、施加载荷和弯曲/旋转力矩。前路固定的应用减少了局部运动，增加了内固定节段的刚度。在临床上，这种脊柱稳定性可能有助于促进融合。
结论
结合接骨板材料的生物可吸收性，生物可吸收前路腰椎接骨板系统被认为具有生物力学优势。
OBJECT
An in vitro biomechanical study was conducted to determine the effects of anterior stabilization on cage-assisted lumbar interbody fusion biomechanics in a multilevel human cadaveric lumbar spine model.
METHODS
Three spine conditions were compared: harvested, bilateral multilevel cages (CAGES), and CAGES with bioabsorbable anterior plates (CBAP), tested under flexion-extension, lateral bending, and axial rotation. Measurements included vertebral motion, applied load, and bending/rotational moments. Application of anterior fixation decreased local motion and increased stiffness of the instrumented levels. Clinically, this spinal stability may serve to promote fusion.
CONCLUSIONS
Coupled with the bioabsorbability of the plating material, the bioabsorbable anterior lumbar plating system is considered biomechanically advantageous.
