Intraspine治疗单节段腰椎间盘突出症的临床疗效

Primary clinical outcomes of Intraspine for treatment of single-segment lumbar disc herniation

[目的]探讨Intraspine治疗单节段腰椎间盘突出症的中短期临床疗效。[方法]回顾性分析本院2017年8月~2019年3月采用单纯开窗减压,髓核摘除,椎板间Intraspine置入治疗的80例单节段腰椎间盘突出症患者,平均年龄(47.32±5.13岁)。采用视觉模拟评分(VAS)和Oswestry功能障碍指数(ODI),以及影像测量椎间盘后缘高度度和椎间孔高度评价临床结果。[结果]所有患者均顺利手术,单节段Intraspine的平均手术时间(55.09±12.45)min,平均出血量(49.82±19.93) ml。随访12~24个月,平均(17.62±5.04)个月。除1例伤口迟发感染,另1例1年复发行翻修术,所有患者均获得良好恢复。末次随访腰痛及腿痛VAS评分、ODI评分与术前比较均显著改善,差异有统计学意义(P<0.05)。影像方面,Intraspine置入节段术后各时间点椎间盘后缘高度和椎间孔高度均较术前增加,差异有统计学意义(P<0.05)。术后1年与术后即刻相比椎间盘后缘高度和椎间孔高度无显著改变(P>0.05)。[结论]椎板间动态稳定系统Intraspine治疗单节段腰椎间盘突出症的中短期疗效满意。

[Objective] To explore the primary clinical outcomes of Intraspine for treatment of single-segment lumbar disc herniation. [Methods] A retrospective study was conducted on 80 patients who aged(47.32±5.13) years on average, and underwent fenestration, discectomy and Intraspine implantation for single-segment lumbar disc herniation from August 2017 to March 2019 in our hospital. The visual analog scale(VAS) for pain, Oswestry dysfunction index(ODI), as well as posterior disc height(PDH) and foraminal height(FH) measured on radiographs were used for evaluation of the clinical outcomes. [Results]All the patients had operation finished smoothly with operation time for single-segment Intraspine of(55.09±12.45) minutes,and blood loss of(49.82±19.93) ml. The follow-up period lasted for 12~24 months, with an average of(15.62±5.04) months. Except delayed wound infection in 1 case and revision operation for recurrence in another case at 1 year after primary operation,all patients got satisfactory recovery. The VAS and ODI scores significantly decreased at the latest follow-up compared with those before operation(P<0.05). In term of radiographic assessment, the PDH and FH significantly increased postoperatively compared with those before operation(P<0.05), and remained unchanged among the time points postoperatively(P>0.05).[Conclusion] This interlaminar dynamic stabilization device, the Intraspine, does achieve satisfactory primary clinical outcomes for single-segment lumbar disc herniation.
