目的：评价前路经枢椎体至寰椎侧块螺钉内固定三维稳定性。
方法：16具成人标本(C0–C3),对每一标本分别测定完整状态(第1组)、齿状突Ⅱ型骨折(第2组)、后路经关节螺钉内固定术(Magerl技术)(第3组)、 前路经枢椎体至寰椎侧块螺钉内固定(第4组)4种状态下的三维运动范围，并进行统计学分析。
结果：1组与其他3组、2组与其他3组比较差异有统计学意义(P<0.001).前路经枢椎体至寰椎侧块螺钉内固定与后路Magerl螺钉内固定均能显着减少寰枢关节各方向运动范围，两种固定方法差异无统计学意义(P>0.05).
结论：前路经枢椎体至寰椎侧块螺钉内固定的三维稳定性与后路Magerl螺钉内固定术相当，为寰枢椎不稳定及脱位患者的治疗提供了一种可靠的手术选择。 |

Abstract:
Objective: To determine the three-dimensional stability of C1-C2 after anterior approach screw fixation through C2 vertebral body to C1 lateral mass for C1-C2 instability or dislocation.
Methods: The three-dimensional range of motion of atlantoaxial joint were measured in 16 human cadaveric specimens under four conditions:the intact state(1st group),odontoid fracture of typeⅡ (2nd group),instrumentation with posterior C1-C2 trans-articular screw fixation(Magerl technique)(3rd group) and anterior approach screw fixation through C2 vertebral body to C1 lateral mass(4th group) respectively.
Results: There was generally significant difference between 1st group and other groups and between 2nd group and other groups by statistics analysis(P<0.001). Range of motion significantly decreased in 3rd group and 4th group in all directions. There was generally no significant difference between the two methods by statistical analysis(P>0.05).
Conclusion: Anterior approach screw fixation through C2 vertebral body to C1 lateral mass provides satisfied stability. It provides the equivalent effect to Magerl technique. It is a kind of reliable surgery choice for the treatment of instability or dislocation of C1-C2 joint. |
