腰椎纤维环缝合技术的研究进展

Research progress of lumbar annulus suture

腰椎间盘突出症(lumbar intervertebral disc herniation,LDH)是造成腰神经根压迫并产生腰腿痛的主要原因,髓核摘除术是一种有效的减压方法,但临床行髓核摘除术可能损伤或者切开纤维环,这必然会破坏纤维环的完整性,不仅使其生物力学功能下降,并且很容易出现椎间盘退变加速、椎间隙变窄甚至髓核再次突出等情况。术后如何避免这些问题就成为很多学者关心研究的一个课题,纤维环缝合技术就是其中一个重要的研究热点。随着这方面研究增加并初步应用于临床,利用纤维环缝合技术恢复髓核摘除术后纤维环的完整性和生物力学功能、防止髓核再次突出已初显成效。现对腰椎纤维环缝合技术目前的动物实验和临床研究进展等问题综述如下。

Lumbar disc herniation( LDH) is a common cause of low back and leg pain. Surgical intervention( discectomy to remove the herniated nucleus pulposus) will be recommended after failed conservative treatment. Annulus suture has been proposed to reduce re-herniation due to fissures on the annulus, showing effectiveness in maintaining the integrity and biomechanical functions of the annulus. This article will review the progress of animal experiment, equipment and clinical research on lumbar annulus suture.
