腰椎后路非融合技术生物力学研究进展

为避免融合术后相邻节段退变的问题，腰椎后路非融合技术相应出现并很快发展。但目前临床应用时间较短，相关基础研究尚不充分。本文总结了当前对腰椎后路非融合固定器械的生物力学评价，包括其对腰椎的活动度、椎间盘内压力、腰椎小关节的影响，以及相应的生物力学研究方法，通过这些研究，我们认为后路非融合技术可以用于治疗退变性腰椎疾患，有着很好的发展前景，同时也发现还有很多方面需要进一步深入研究。

Advances in biomechanics of posterior non-fusion technologies in lumbar spine

In order to avoid the adjacent segment disease resulted from spine fusion, the concept of non-fusion technology arose and is becoming popular. The posterior non-fusion devices in lumbar spine have used clinically, but no long-term follow-up data about these devices is reported, and the basic study is not enough. We reviewed the biomechanical evaluation about posterior non-fusion technologies in lumbar spine, including range of motion, intradiscal pressure, facet joints and the biomechanical methods. We found these non-fusion technologies have advantages in treating lumbar degenerative diseases, but more deep study needs to be done.
