Abstract Objective: To investigate the effects of stability of the L_4/5 lumbar, biomechanical properties and biocompatibility of adjacent segments for interspinous fusion cage. Methods: 18 fresh adult frozen spine specimens were collected, including L_4/5 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 anteflexion, 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 control group (P all<0.05). Conclusion: L_4/5 lumbar for interspinous fusion cage can effectively improve the vertebral activity and keep its stability, which is helpful to shorten the stress of the intervertebral disc.

Key words： Interspinous fusion cage Stability Biomechanics Biocompatibility
