摘要

目的:评价前路经枢椎体至寰椎侧块螺钉联合Gallie法内固定重建寰枢椎不稳的三维稳定性。方法:25具成人标本（C0

）

随机分成5组:完整状态（Intact组）、齿状突Ⅱ型骨折（OTF组）、Magerl螺钉内固定术（PTS组）、前路经枢椎体至寰椎侧块螺钉内固定（ASM组）、前路经枢椎体至寰椎侧块螺钉联合Gallie法内固定术（ASMG组）

每组5个标本。测定5种状态下的寰枢椎三维运动范围

并进行统计分析。结果:ASMG组、PTS组及ASM组都显著减少寰枢椎的三维运动范围;ASMG组与PTS组及ASM组在屈伸及左右侧弯方面有显著性差异（P

0.05）

在左右旋转方面无显著性差异（P

0.05）。结论:前路经枢椎体至寰椎侧块螺钉联合Gallie法内固定在重建寰枢关节的稳定有独特的优势

更能控制屈伸及左右侧弯。为陈旧性寰枢椎不稳定或脱位患者提供了一种可靠的手术方式。

Abstract

Objective:To determine the three-dimensional stability of atlantoaxial reconstruction with anterior approach screw fixation through C2 vertebral body to C1 lateral mass and Gallie’s technique for C1~2 instability.Methods:25 human cadaveric specimens were randomly divided into 5 groups.The three-dimensional range of motion C1 relatively C2 was measured under five different conditions

the intact state(intact group)

odontoid tape Ⅱ fracture(group OTF)

fixation with posterior C1~2 transar- ticular screw(group PTS)

anterior approach screw fixation through C2 vertebral body to C1 lateral mass(group ASM)

ASM and Gallie’s technique(group ASMG). The obtained data were statistically analyzed. Results:The range of motion in all directions group ASMG

ASM and PTS was significantly decreased.There was significant difference among group ASMG

ASM and PTS in flexion/extension and lateral bendings by statistical analysis(P<0.05)

and no difference in axial rotation by statistical analysis (P>0.05). Conclusion:In vivo biomechanics studies showed that ASMG had unique superiority in the reconstruction of the atlantoaxial stability

especially in controlling the instability of flexion/extension and lateral bendings.It was one kind of reli- able surgical choice for the treatment of the obsolete insta- bility or dislocation of C1~2 joint.
