| 目前，下颈椎后路螺钉固定除侧块螺钉和椎弓根螺钉技术已普遍应用外，经关节螺钉和经椎板螺钉固定技术也逐渐被重视。本文就此介绍下颈椎后路4种螺钉固定方式，并对各自固定技术的生物力学研究现状进行综述。生物力学研究内容包括三维稳定性、抗拔出力、置钉技术和螺钉特点等。侧块螺钉和椎弓根螺钉技术，因其优越的三维稳定性和较强的抗拔出力，已经作为下颈椎不稳的一种有效固定方法。经关节螺钉固定作为一种新的下颈椎后路固定方法，具有广范的手术适应证，并且该技术相对安全、简易，临床上也取得了良好的疗效。经椎板螺钉固定技术临床应用不多，但通过解剖学和生物力学研究证实，该技术可成为临床上可行的补救技术。上述4种下颈椎后路螺钉固定技术，各有其优劣，临床应用也各不相同，通过对这些技术的生物力学研究，将有助于下颈椎后路螺钉内固定技术的发展，更有效的指导临床工作。 |

| Biomechanical study on the posterior screw fixation in the lower cervical spine |
|
| Abstract:So far,the fixation in the lower cervical spine through posterior approach technology has commonly been used, besides the lateral screw and pedicle screw techniques,transarticular screw and laminar screw techniques have being paid more attention recently. This article introduced four screw fixation ways in the lower cervical spine through posterior approach and reviewed the recent biomechanics studies of four screw fixation techniques. The biomechanics study includes stabilization,pollout strength,insertion technique,and screw characteristic and so on. Lateral screw and pedicle screw techniques have become an effective internal fixation way for the lower cervical spine instability because of their superior stabilization and higher pollout strength. Transarticular screw fixation has become a new way to fix the lower cervical spine through posterior approach,which has widely surgical indications. Besides,this technique is relatively safe,simple and has achieved favorable curative effect in clinic. Laminar screw fixation technique is rarely used in clinic,but the study of anatomy and biomechanics confirmed that this technique can be applied as a salvage technique in clinic. Above four techniques of the screw fixation in the lower cervical spine through posterior approach have advantages and disadvantages,respectively,and the application in clinic is different. Through the biomechanics study of these techniques will contribute to the development of the techniques of the screw fixation in the lower cervical spine through posterior approach and guide the clinical work effectively. |
