非融合技术在老年退变性腰椎疾病中的应用

Non-fusion motion preservation stabilization techniques for degenerative lumbar diseases in the elderly

腰椎非融合外科技术因不固定脊柱节段，也许较融合术具有更多的优势。本文讨论了对于适合的老年患者，腰椎非融合术的主要类型、进展、适应证及禁忌证、存在的优势与不足。并对非融合技术在老年退变性腰椎疾病中的应用前景进行了展望。我们认为，各主要非融合技术在延缓治疗节段椎间盘退变的速度、保留该节段的运动功能、预防相邻节段的退变、减轻临床症状及改善生活质量等方面都显示出较融合术所具有的更多优势和更少的负面影响。

The non-fusion dynamic stabilization techniques maintain the motion of the lumbar vertebrae without fusion spinal segments, so it may have more advantages than fusion surgery. In this review, we discussed the main types, advance, indications and contraindications, advantages and disadvantages of the lumbar non-fusion surgical treatment for the eligible elderly patients. We believed that major non-fusion techniques had more advantages and less disadvantages in delaying the process of disc degeneration of the targeted segment, preserving the motion of segment, preventing degeneration of adjacent segments, alleviating clinical symptoms, and improving quality of life. There would be great prospect of the lumbar non-fusion surgery in the treatment of degenerative lumbar diseases.
