目的:对寰枢椎齿状突Ⅱ型骨折实验模型的4种后路内固定方式下的三维运动范围进行实验研究,为临床选择内固定方法提供生物力学依据。
方法:实验采用10具新鲜人体寰枢椎标本(C0-C3）制成寰枢椎齿状突Ⅱ型骨折实验模型,使实验模型在不同固定方式下模拟人体寰枢椎的三维运动(前屈、后伸、左右侧屈、左右旋转),并选用应变式传感器对运动范围的角度进行测量研究。
结果:在1.53Nm作用下4点固定的寰枢椎三维运动范围最小,其前屈、后伸、左右侧屈、左右旋转角度分别为1.8°、2.0°、1.2°、1.1°、3.2°、3.0°。
结论:实验研究表明4点固定有更好的生物力学稳定性,采用应变式传感器能够对寰枢椎的三维运动进行测量,具有直观、实时、方法简单、结果可靠等优点。 |

Abstract:
Objective:To study three-dimensional movement of four type of posterior atlantoaxial fixation techniques of type Ⅱ odontoid process fracture.
Methods:Ten fresh cadaveric specimens （C0-C3）were studied to compare three-dimensional movement of four type posterior atlantoaxial fixation techniques by strain sensor.
Results:According to experiment,the movement range of four-point fixation techniques was least.Range of three-dimensional movement of atlantoaxial joint in four-point fixation techn ique for flexion, extension, left lateral bend ing, right lateral bending, and left axial rotation, right axial rotation were 1.8°,2.0°,1.2°,1.1°,3.2°,3.0°.
Conclusion:Four-point fixation techniques is superior to other fix ation techniques. The study shows that this method had following mer it: direct viewing, real time, simple in measurement and reliable in result. |
