摘要:
目的 探讨经皮颈椎低温等离子髓核消融术(PCN)与后路经皮内镜下颈椎间盘髓核摘除术(PPECD)治疗神经根型颈椎病的临床效果。 方法 选取安徽医科大学第一附属医院疼痛科2019年5月—2021年6月治疗的67例包容型单节段颈椎间盘软性突出患者,根据手术方法分为PPECD组(35例)和PCN组(32例)。于术前、术后多个时间点分别通过VAS评分评价疼痛变化情况,颈椎功能障碍指数(NDI)评估颈椎功能恢复情况;术后1年随访,采用改良的MacNab标准评估手术疗效。 结果 2组患者均顺利完成手术,且术后随访记录完整。2组患者术前一般资料比较差异无统计学意义。PCN组手术时间[(42.0±6.4)min]明显短于PPECD组[(94.7±6.3)min,P<0.001]。与术前相比,2组患者术后各时间点疼痛评分和颈椎功能障碍指数均显著改善(P<0.05)。根据MacNab标准,PPECD组患者治疗优良率(82.9%,29/35)高于PCN组(75.0%,24/32),但差异无统计学意义(P>0.05)。2组患者均未观察到严重的术后并发症。 结论 就手术耐受较差的患者而言,PCN可成为包容型单节段颈椎间盘软性突出的神经根型颈椎病患者行PPECD治疗的良好替代方案。 -

Abstract:Objective To explore the clinical effects of percutaneous cervical nucleoplasty (PCN) and posterior percutaneous endoscopic cervical discectomy (PPECD) in the treatment of cervical spondylotic radiculopathy. Methods Sixty-seven cases of cervical spondylotic radiculopathy due to a single-level contained soft-disc herniation in the Department of Pain Medicine of the First Affiliated Hospital of Anhui Medical University from May 2019 to June 2021 were selected, and divided into Group PPECD (n=35) and Group PCN (n=32) according to surgical methods. Pain was assessed by VAS scores at multiple time points before and after surgery, and cervical functional recovery was evaluated using the cervical dysfunction index (NDI). The modified MacNab criteria were used to evaluate the surgical efficacy at the final follow-up. Results All patients completed the surgery and had complete follow-up data. There was no significant difference in the general preoperative conditions of the two groups of patients. The operation time of PCN treatment [(42.0±6.4) min] was significantly shorter than that of the PPECD group [(94.7±6.3) min, P < 0.001]. Compared with those before surgery, the VAS scores and NDI index of the two groups of patients at each postoperative time were significantly improved (P < 0.05). According to the Macnab standard, the clinical effective rate of patients treated with PPECD (82.9%, 29/35) was higher than that of PCN (75.0%, 24/32), but the difference was not statistically significant (P > 0.05). No serious postoperative complications were observed in either group of patients. Conclusion For patients with poor tolerance to surgery, PCN can be a good alternative to PPECD for patients with cervical spondylotic radiculopathy due to a single-level contained soft-disc herniation. -
