目的:探讨脊柱内镜下窦椎神经毁损术治疗椎间盘源性腰痛的临床疗效。方法:基于窦椎神经的解剖学研究，对2018年7月至2019年2月收治的40例单节段椎间盘源性腰痛患者采用脊柱内镜下腰窦椎神经毁损术治疗，男19例，女21例；年龄（35±10）岁（范围24~55岁）。责任节段包括Ln 3，4 4例、Ln 4，5 31例、Ln 5Sn 1 5例。术前疼痛视觉模拟评分（visual analogue scale，VAS）为（4.5±0.9）分，Oswestry功能障碍指数（Oswestry disability index，ODI）为49.7%±14.0%。于病变节段双侧椎弓根投影的外侧缘连线与椎间盘投影上缘交点区域各注入质量浓度0.05 g/L的利多卡因0.1~0.3 ml，阻滞试验阳性。通过双侧入路椎间孔镜直视下用射频刀头或神经剥离子毁损窦椎神经起始段。术后1、3、6、12个月随访，观察VAS评分及ODI指数的变化。n 结果:内镜下观察腰窦椎神经呈细丝状，主支紧贴椎间盘向椎管内走行，副支于椎间盘的后外侧缘交叉进入椎间盘或椎体后缘；与脊动脉中央后支伴行的神经为窦椎神经主支，呈紧张状态，随神经根的活动而活动；沿窦椎神经主支向外侧移动工作通道，可观察到窦椎神经在神经节腹侧的起始位置。40例患者均顺利完成窦椎神经毁损术。术后VAS评分降低至1个月（1.7±0.9）分、3个月（1.3±0.9）分、6个月（1.2±0.8）分、12个月（1.3±0.7）分，与术前比较差异有统计学意义（n F=116.7，n P=0.00）；术后12个月VAS评分改善率为68.9%±17.1%（范围33.3%~100.0%）；6例患者术后12个月腰痛VAS评分较术后6个月升高，包括Ln 3，4 1例、Ln 4，5 2例、Ln 5Sn 1 3例。40例患者术后ODI指数降低至1个月18.3%±5.2%、3个月14.5%±4.3%、6个月13.6%±3.7%、12个月12.8%±3.0%，与术前比较差异有统计学意义（n F=237.7，n P=0.00）；术后12个月ODI改善率为72.0%±11.6%（范围33.3%~88.9%）。n 结论:脊柱内镜下窦椎神经毁损术可明显改善Ln 3，4、Ln 4，5节段椎间盘源性腰痛患者12个月内的疼痛和功能，对Ln 5Sn 1节段患者6个月内效果较好。n “,”Objective:To explore the clinical effects of endoscopic sinuvertebral nerves neurotomy for discogenic low back pain.Methods:Based on the anatomical research of sinuvertebral nerves, a total of 40 patients, including 9 males and 21 females aged 35±10 (24-55) years, with single-segment discogenic low back pain were treated with endoscopic sinuvertebral nerves neurotomy in our hospital from July 2018 to February 2019. The operating section included 4 cases of Ln 3,4 (10.0%, 4/40), 31 cases of Ln 4, 5 (77.5%, 31/40), and 5 cases of Ln 5Sn 1 (12.5%, 5/40). The preoperative visual analogue scale (VAS) score was 4.5±0.9 with the preoperative Oswestry disability index (ODI) score 49.7%±14.0%. For diagnostic nerves block, lidocaine (0.1-0.3 ml of 0.05 g/L) was successfully injected into the intersection of the lateral edge of the bilateral pedicle projection and the upper edge of the intervertebral disc projection. The initial segment of the sinuvertebral nerves was destroyed by a radiofrequency blade or a nerve dissector after bilateral percutaneous transforaminal endoscopic. All cases were followed up at 1, 3, 6 and 12 months after surgery, observing the changes in VAS and ODI.n Results:Filamentous lumbar sinuvertebral nerve was observed under endoscope with its main trunk tranversed into the spinal canal against the intervertebral disc. The deputy trunk crossed at the posterolateral edge of the intervertebral disc and entered the intervertebral disc or the posterior edge of the vertebral body. By moving along with postcentral branches of spinal artery, the main trunk of sinuvertebral nerve was with tension and was capable of moving with the nerve root. In spite of moving the working channel along the main trunk of the sinuvertebral nerve laterally, the starting point of the sinuvertebral nerve at the ventral ganglion could be observed. All 40 patients successfully completed the sinuvertebral nerve destruction. The VAS was reduced to 1.7±0.9, 1.3±0.9, 1.2±0.8, 1.3±0.7 at 1, 3, 6 and 12 months after sugery respectively, which were significantly lower than those at pre-operation (n F=116.7, n P=0.00). The improvement rate of VAS in 40 cases was 68.9%± 17.1% (33.3%-100.0%) at 12 months after operation. The VAS score in 6 cases was higher at 12 months after surgery than that preoperatively (n t=4.2, n P=0.48), namely 1 case of Ln 3, 4, 2 cases of Ln 4, 5, and 3 cases of Ln 5Sn 1. In all cases, the ODI was reduced to 18.3%±5.2%, 14.5%±4.3%, 13.6%±3.7%, 12.8%±3.0% points at 1, 3, 6 and 12 months after surgery respectively, which were significantly lower than those before surgery (n F=237.7, n P=0.00). The improvement rate of ODI was 72.0%±11.6% (33.3%-88.9%) at 12 months after surgery in all cases.n Conclusion:The destruction of sinuvertebral nerve after transforaminal endoscope could improve the pain and function in patients with discogenic low back pain at Ln 3,4 and Ln 4, 5 segments within 12 months. For patients with discogenic low back pain at Ln 5Sn 1 segment, the clinical effects could be better within 6 months.n
