腰椎后路非融合技术生物力学研究进展

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

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继出现并得到快速发展,但在临床应用时间较短,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,指出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,还有很多方面需要进一步深入研究的问题。

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.
