微创内镜辅助下颈椎前路减压融合术治疗神经根型颈椎病的疗效

The clinic effect of mini open endoscope assisted-ACDF for cervical spondylotic radiculopathy

目的研究微创内镜辅助下颈椎前路减压融合术(mini open endoscope assisted-ACDF,MOEA-ACDF)治疗神经根型颈椎病(cervical spondylotic radiculopathy,CSR)的临床疗效与安全性。方法回顾性纳入2022年2月至2023年3月于医院因CSR接受手术的患者,包括常规ACDF组与MOEA-ACDF组,评估患者术前一般情况、手术时间,植骨融合情况,手术后VAS疼痛评分、JOA评分、C_(2-7)Cobb角、手术节段前柱高度,以及伤口感染、切口愈合不良、血肿形成、脑脊液漏、神经损伤、内固定相关并发症。结果纳入常规ACDF组患者41例,MOEA-ACDF组患者41例。两组患者术前一般情况差异无统计学意义,具有可比性。两组之间相比,术后VAS疼痛评分、JOA评分、C_(2-7)Cobb角、手术节段前柱高度差异无统计学意义;与常规ACDF组相比,MOEA-ACDF组手术时间稍长(P=0.02)。与术前相比,两组患者术后VAS疼痛评分下降,JOA评分、C_(2-7)Cobb角、手术节段前柱高度均较术前改善,差异有统计学意义。术后均无患者出现伤口感染、切口愈合不良、血肿形成、脑脊液漏、神经损伤等并发症。结论MOEA-ACDF技术治疗CSR,可以有效缓解临床症状,恢复颈椎高度与曲度,获得与常规ACDF术相似的临床效果,具有良好的有效性和安全性。虽然MOEA-ACDF技术手术时间较常规ACDF术稍延长,但其具有手术视野清晰开阔、深部聚焦、照明良好、出血少、创伤小的优点,进而方便术者进行颈椎间盘摘除、神经根管松解、后纵韧带切除等操作,减少神经、脊髓、硬膜和椎动脉损伤,是一项值得推广和应用的技术。

Objective Study clinic effect of mini open endoscope assisted-ACDF(MOEA-ACDF)for cervical spondylotic radiculopathy(CSR).Methods From February 2022 to March 2023,CSR patients receiving ACDF in the hospital were included in this study,including conventional ACDF group and MOEA-ACDF group.The preoperative data,operative timeand bone graft fusionwere recorded,VAS score,JOA score,C2-7 Cobb angle and anterior column height of the surgical segment were assessed before and after surgery,and complications were recorded,including wound infection,poor wound healing,hematoma formation,cerebrospinal fluid leakage,nerve injury,and complications related internal fixation.Results There were 41 patients in the conventional ACDF group and 41 patients in the MOEA-ACDF group.Between the two groups,there was no statistically significant difference in preoperative general condition,and there was no statistically significant difference in postoperative VAS pain score,JOA score,C2-7 Cobb angle,and anterior column height.Compared with the conventional ACDF group,the MOEA-ACDF group had a slightly longer surgical time(P=0.02).Compared with pre-operation,the VAS pain scorewas reduced,JOA score,C2-7 Cobb angle,and anterior column height were improved in both groups after operation.There were no postoperative complications such as wound infection,poor wound healing,hematoma formation,cerebrospinal fluid leakage,or nerve damage in both groups.Conclusions The MOEA-ACDF technology for treating CSR can effectively alleviate clinical symptoms,restore cervical spine height and curvature,and achieve clinical effects similar to conventional ACDF surgery,having good effectiveness and safety.Although the operation time of MOEA-ACDF technology is slightly longer than conventional ACDF,it has the advantages of clear and broad surgical field,deep focus,good lighting,less bleeding,and minimal trauma,which makes it convenient for the operator to perform cervical disc removal,nerve root canal release,posterior longitudinal ligament resection,and reduce nerve,spinal cord,dura mater,and vertebral artery injuries.It is a technology worth promoting and applying.
