摘　　要：目的:探讨3种颈椎前路钉板系统(Orion、Codman、Window)在颈椎前路单椎间减压植骨融合模型中的生物力学为临床应用提供生物力学依据。方法:采用6具小牛颈椎标本,测定其正常颈椎相应节段的活动范围(ROM),制成模型,依次测试Orion、Codman、Window固定后颈椎相应节段的ROM。结果:3种钢板固定后在前屈、后伸、旋转时的ROM均比正常小,其中前屈时3种钢板与正常颈椎相比差异有显著性意义(P<0.05)。后伸时Codman、Window与正常颈椎相比差异有显著性意义(P<0.05)。Orion与正常颈椎差异无显著性意义(P>0.05)。旋转侧屈时3种钢板与正常颈椎差异均无显著性意义(P>0.05)。3种钢板之间差异无显著性意义(P>0.05)。结论:支持3种钢板在颈椎在单椎间减压植骨融合中应用。Objective:To compare the constructive stability with three kinds of anterior cervical plates in clinically simulated single-level anterior intervertebral decompression and fusion model to provide biomechanical basis for clinical application.Methods:6 fresh calf cervical spine specimens. After intact specimen underwent test, in each specimen, the following construct were tested successively in model: fixation with Orion, Codman, Window respectively.Results:The ROM of the following construct with Orion, Codman, Window respectively were less significantly than those of the intact specimens in flexion(P<0.05). In extension, the ROM of construct with Codman and Window were less significantly than those of the intact specimens (P<0.05). But there was no significantly difference between the constructs with Orion and the intact spine specimens (P>0.05). There were no significantly difference among the constructs with three kinds of plate respectively and the intact specimens in lateral bending and rotation. However, there were no significantly difference among Orion, Codman and Window(P>0.05). Conclusions:Three kinds of plates provide effective stability for cervical spine.
