取新鲜尸体标本４具制作ＦＳＵ试件８个，仿颈前路减压植骨融合术制作３种实验模型，进行三维运动生物力学评估，对试件施加２．３４Ｎｍ的最大力矩，测出前屈，后伸，侧弯及旋转的运动范围（ＲＯＭ），结果显示：（１）在屈曲运动时，稳定性骨折组（ＳＦ）植骨后刚度增加平均２９．８％，不稳定性骨折组（ＮＦ１）植骨后，较之正常组刚度下降８．６％，但上钢板后刚度增加１８．９％（２）在过伸运动时，稳定性和不稳定性骨折线植骨

ight Function spinal unites(FSU) were studied after anterior decompression and interbody fusion.Applied a loads of 2.34 Nm,the range of movement(ROM) were dicutmented for each FSU specimen.Results:1)In flexion,compared with the intact FSU group,the stiffness increased an average of 29.8% for SF group,decreased 8.6% for NF 1 group and increased 18.9% after the internal fixation were used.2)In extention,the stiffness didn′t increase for both SF and NF 1 groups,but increased greatly after the internal fixation were used.3)In bending,the stiffness...
