摘要：

目的　对比经口寰枢椎复位钢板固定系统(TARP)与后路椎弓根钉棒固定系统的三维生物力学稳定性，为临床应用提供实验依据。方法 6具新鲜上颈椎尸体标本（C0~3），随机分为正常组、　TARP组、后路钉棒组。每组标本均利用美国魔神运动分析技术公司步态分析系统（Motion Analysis, co. 6Eagle系统）测量屈伸、侧屈、旋转各个方向的运动范围（ROM），并进行统计学分析。结果　前路TARP钢板组与后路椎弓根钉棒组在屈伸、侧屈、旋转各个方向上与完整标本差异显著。前路TARP钢板组与后路椎弓根钉棒组在屈伸、侧屈、旋转各个方向均无显著差异。结论　前路TARP固定系统具有与后路椎弓根钉棒固定系统相当的三维稳定性，具有良好的生物力学性能，前路TARP系统可作为寰枢椎可靠内固定的选择方法之一。

Abstract:

Objective To compare the in vitro biomechanics of Type Ⅲ Transoral Atlantoaxial Reduction Plate(TARP) system, with that of conventional posterior atlantoaxial pedicle screw-rods system, and provide biomechanical basis for clinical application. Methods 6 fresh-frozen human cadaveric cervical spines with occiput (C0~3) were used. Three different groups were examined: (1) control group (intact) (n= 6); (2) TARP group (n= 6); (3) pedicle screw-rods group (n= 6). All specimens were evaluated in flexion-extension, left-right bending, and left-right axial rotation with Motion Analysis in a cadaveric C1-2 fixation model with a nondestructive flexibility method using a nonconstrained skill. Results Stiffness in any direction was significantly higher in the TARP group and pedicle screw-rod group than in control group (intact). The difference in stiffness between the TARP group and pedicle screw-rod group was not statistically significant. Conclusions Experimentally, the TARP-Ⅲ system fixation and pedicle screw-rods fixation methods were significantly stiffer than the control group. The anterior TARP-Ⅲ system provided stiffness equal to posterior pedicle screw-rods fixation. Therefore, TARP-Ⅲ system seems reasonable that the reliable and rigid fixation would be the method of choice.
