L4/5棘突间植入椎间融合器的稳定性及对相邻节段的生物力学特性和生物相容性的影响
The Stability of L4/5 Interspinous Interbody Fusion Cage and its Effects on Biomechanical Properties and Biocompatibility of Adjacent Segments
摘要
Abstract
Objective:To investigate the effects of stability of the L4/5 lumbar, biomechanical properties and biocompatibility of adjacent segments for interspinous fusion cage. Methods: 18 fresh adult frozen spine specimens were collected, including L4/5 lumbar for interspinous fusion cage as the study group, and normal specimens as the control group, with 9 specimens in each group. The specimens of two groups were numbered and implanted in vivo and fixed by fixators. Results:The strain changes in different implantation for anteflex-ion, center compression, lateroflexion and rear protraction in the study group were smaller than in the control group ( P all<0.05) . Under the maximum load of 600 N, the angular displacement and linear displacement in left lateral flexion, levorotation, anteflexion and rear protraction in the study group were lower than in the con-trol group ( P all<0.05) . Conclusion:L4/5 lumbar for interspinous fusion cage can effectively improve the ver-tebral activity and keep its stability, which is helpful to shorten the stress of the intervertebral disc.关键词
