脊柱稳定性重建在腰椎不稳症中的应用

因腰椎退行性病变、创伤、肿瘤、峡部裂等因素造成的腰椎不稳和由此引起的下腰痛已引起广泛的关注，有近20%的腰椎不稳症患者非重建治疗效果不理想，需经重建治疗，目的是充分减压，重建脊柱的稳定性。重建脊柱稳定性的治疗方法种类很多，每一种方法又有其各自的特点，应根据不同患者选用不同的内固定方法并给予融合,以提高融合率, 缩短卧床时间,减少并发症。文章就脊柱稳定性重建的各种治疗方法的适应范围、特点和椎间融合等问题进行了综述。

Application of spinal stability rebuilding in symptomatic lumbar instability

Approximately 20 percent patients with symptomatic lumbar spinal instability, most of which occurs due to symptomatic degenerative lumbar spinal instability, trauma, tumor, and isthmus cleft, have no well results after expectant treatments. So they eventually receive reconstruction treatment to achieve thorough decompression and rebuilding of lumbar spinal stability. There are various kinds of treatments, and each of them has specific features. Therefore, the internal fixation and fusion methods should be selected according to patient condition to improve fusion rate, shorten bed staying duration and reduce complications. This paper summarized indications and features of each kind of operation as well as techniques of the interbody fusion.
