| Abstract: | The effects of cutting-aspiration of nucleus pulposus on the momements of the cervical spine in flexion,extension and lateral bending with fresh cervical spine specimens were tested by means of contacting measement with the dial indicators when loaded with the electronic universal testing machine.The results showed:(1) Cutting-aspiration of nucleus pulposus only removed part of the nucleus pulposus,which was consistent with the clinical observation;(2)The ranges or motion(ROMs) of the operative segment had not increased in direction of flexion,extension and lateral bending after cutting-aspiration of nucleus pulposus:(3)After nucleotomy,the ROMs corresponding upon the operative segment apparently increased in flexion and extension,but had no change in lateral bending;(4)Hemilaminectomy of cervical spine which was an operation or partial removal of the ligamentum flavum and the lamina only had little afrection on the cervical stability. The biomechanical data can not only demonstrate the reliability of percutaneous dlscectomy,but also present a new enlightement for the clinical therapy of cervical disc herniation with spinal canal stenosis. |
