Efficacy of microscope-assisted anterior cervical discectomy and fusion as well as internal fixation for the treatment of localized ossification of the posterior longitudinal ligament
目的 探析局限型后纵韧带骨化症(OPLL)患者接受显微镜下椎间盘切除融合内固定术(ACDF)治疗的近期与远期疗效情况.方法 回顾性选取2020年2月-2022年2月收治的局限型OPLL患者105例,按照ACDF治疗过程中是否辅助使用显微镜分为显微镜组56例和常规组49例,观察围术期指标、视觉模拟评分法(VAS)评分、健康调查评估量表(SF-36)评分、椎管最狭窄处椎管面积与脊髓前后径、颈椎活动度、椎间隙高度、关节功能[日本骨科医师协会评分(JOA)颈椎病评分及颈部障碍指数(NDI)]及并发症风险.结果 显微镜组平均手术时间(141.85±18.35)min、平均住院时间(10.18±1.58)d短于常规组的(159.46±21.42)min、(12.03±1.82)d,显微镜组术中平均出血量(80.65±7.28)ml少于常规组的(103.52±10.43)mL,差异有统计学意义(P＜0.05);显微镜组术后6个月VAS评分(2.82±0.53)分、SF-36评分(79.56±5.68)分优于常规组的(3.51±0.60)、(72.35±4.77)分,差异有统计学意义(P＜0.05);显微镜组与常规组在术后椎管面积、脊髓前后径上比较[(138.24±24.32)mm2 与(123.62±18.74)mm2,(5.42±0.46)mm 与(4.73±0.51)mm],差异有统计学意义(P＜0.05);显微镜组与常规组在术后6个月颈椎活动度上比较[(25.21±3.37)°与(28.65±3.56)°],差异有统计学意义(P＜0.05);显微镜组并发症发生率为5.36％,低于常规组的18.37％,差异有统计学意义(P＜0.05);显微镜组与常规组JOA、NDI评分在时间、组间和交互效应上比较,差异有统计学意义(P＜0.05).结论 局限型OPLL患者实施ACDF治疗过程中借助显微镜提供清晰视野,并对骨化灶采用磨钻磨除、打薄处理,能更有效地解除脊髓压迫,改善近期疼痛和关节功能状况,降低脊髓损伤等并发症风险.
Objective To explore the short-term and long-term efficacy of anterior cervical dis-cectomy and fusion(ACDF)under microscopic assistance for patients with focal ossification of the posterior longitudinal ligament(OPLL).Methods A total of 105 patients with focal OPLL treated between February 2020 and February 2022 were retrospectively selected.They were divided into mi-croscope group(n=56)and conventional group(n=49)based on whether ACDF was assisted by microscopy.Perioperative indicators,Visual Analogue Scale(VAS)scores,36-item Short-Form Health Survey(SF-36)scores,spinal canal cross-sectional area at the narrowest point,anteroposteri-or diameter of the spinal cord,cervical range of motion,intervertebral height,joint function[Japanese Orthopaedic Association(JOA)cervical spine disease score and Neck Disability Index(NDI)],and occurrence of complication were observed.Results The average operative time and average hospital stay in the microscope group were shorter than those in the conventional group[(141.85±18.35)min and(10.18±1.58)d versus(159.46±21.42)min and(12.03±1.82)d,P＜0.05].The average intraoperative blood loss in the microscope group was(80.65±7.28)mL,which was less than that(103.52±10.43)mL in the conventional group(P＜0.05).The VAS score and SF-36 score at six months postoperatively were better in the microscope group compared to the conventional group[(2.82±0.53)and(79.56±5.68)versus(3.51±0.60)and(72.35±4.77),respectively,P＜0.05].Spinal canal area and anteroposterior diameter of the spinal cord between the two groups postoperatively showed statistically significant differences[(138.24±24.32)mm versus(123.62±18.74)mm,(5.42±0.46)mm versus(4.73±0.51)mm,P＜0.05].The cervical range of mo-tion at six months postoperatively in the microscope group showed significant difference compared with that in the conventional group[(25.21±3.37)°versus(28.65±3.56)°,P＜0.05].The complication rate in the microscope group was lower than that in the conventional group(5.36％versus 18.37％,P＜0.05).Japanese orthopaedic association(JOA)and National Death Index(NDI)scores showed statistically significant between-group and time-point difference(P＜0.05).Conclusion Microscopic assistance during ACDF for focal OPLL provides a clear field of vision and facilitates effective decompression of the spinal cord by using a drill to remove and thin the ossified focus,thereby improving short-term pain and joint function while reducing the risk of spinal cord in-jury and other complications.
