【摘要】： 目的:研究颈椎单侧关节突交锁后椎间孔上、下、内、外各壁的压力变化,以生物力学方法探讨颈椎单侧关节突交锁后椎间孔形态学的变化 方法:对四具颈椎标本,固定使C4-5为唯一运动节段,在椎间孔的内侧壁、外侧壁、上壁及下壁四壁贴电极片,连接相应测量仪器以测量交锁前后应变。将标本一端置于夹具中,另一端置于扳手中。向上述运动节段加载相应剪切力(屈曲+旋转),剪切力的大小由静态电阻应变仪反映出来,测试出骨折脱位时的最大剪切力。同时测量旋转角度并观察其软组织损伤情况。 结论:交锁侧及对侧的外侧壁及下壁均受到拉力,且被拉伸;内侧壁及上壁均受到压力,且被压缩。交锁侧外侧壁所受的剪切力最大,且位移最大,其次为内侧壁。交锁侧外侧壁所受的拉力远远大于对侧外侧壁的拉力,二者差别具统计学意义。内侧壁,上下壁的交锁侧与对侧受力无显著差别,无统计学意义。交锁侧各壁受力大小有量的差别,但无统计学意义。关节突分离所需要力为70N,旋转角度为19.75°,棘上韧带,棘间韧带完全断裂,关节囊破坏,前纵韧带和后纵韧带部分断裂,1/2以上纤维环破坏.
[Abstract]:Objective: to study the pressure changes of superior, inferior, inner and outer walls of intervertebral foramen after unilateral interarticular process interlocking. A biomechanical study on the morphological changes of intervertebral foramen after unilateral interarticular process interlocking of cervical vertebrae. In four cervical vertebrae specimens, C4-5 was fixed as the sole motor segment, and the medial wall and lateral wall of the intervertebral foramen were fixed. The upper and lower wall four-wall electrodes are attached to the corresponding measuring instruments to measure the pre-and post-lock strain. Place one end of the specimen in the fixture and the other end in the wrench. The shear force (buckling rotation) is loaded to the above motion segment. The shear force is reflected by the static resistance strainmeter and the maximum shear force is measured when the fracture is dislocated. At the same time, the rotation angle was measured and the soft tissue injury was observed. Conclusion: the lateral and inferior walls of the interlocking and contralateral sides are subjected to tension and tension, and the medial and superior walls are subjected to pressure and compression. The lateral wall of the interlocking side is subjected to the largest shear force and the largest displacement, followed by the inner lateral wall. The tension of the lateral wall of the interlocking side was much greater than that of the lateral wall of the contralateral side, and the difference was statistically significant. There was no significant difference between the interlocking side and the contralateral side of the inner wall, upper and lower wall, and there was no statistical significance. There was a significant difference in the strength of each wall of the interlocking side, but there was no statistical significance. The force required for the separation of the articular process was 70 N and the rotation angle was 19.75 掳. The supraspinal ligament, the interspinous ligament, the complete rupture of the interspinous ligament, the destruction of the joint capsule, the partial rupture of the anterior longitudinal ligament and the posterior longitudinal ligament, and the destruction of more than 1 / 2 of the fibrous ring were observed.
