颈椎后路椎管扩大成形术治疗K线阴性颈椎后纵韧带骨化症患者的效果分析

Effect Analysis of Posterior Cervical Enlarged Spinal Canal Plasty in Patients with K-negative Ossification of Posterior Longitudinal Ligament of the Cervical Spine

目的:探究颈椎后路椎管扩大成形术治疗K线阴性颈椎后纵韧带骨化症患者的效果。方法:选择南通市第一人民医院2017年2月—2022年2月收治的88例K线阴性颈椎后纵韧带骨化症患者,根据随机数字表法将其分为观察组44例和对照组44例,对照组采用传统前方入路手术治疗,观察组采用颈椎后路椎管扩大成形术。比较两组患者手术时间、住院时间、颈椎功能障碍指数(NDI)、日本骨科协会(JOA)评分、术后2个月并发症发生情况。结果:相比于对照组,观察组手术时间、住院时间均较短(P<0.05)。两组患者在术后1周、术后2个月NDI均呈现下降趋势,观察组NDI均低于对照组(P<0.05)。两组患者在术后1周、术后2个月JOA评分均呈现升高趋势,相比于对照组,观察组JOA评分均较高(P<0.05)。观察组并发症发生率低于对照组(P<0.05)。结论:颈椎后路椎管扩大成形术治疗K线阴性颈椎后纵韧带骨化症患者,有利于降低患者NDI,改善JOA评分,降低并发症发生率。

Objective:To investigate the effect of posterior cervical enlarged spinal canal plasty in the treatment of K-negative ossification of posterior longitudinal ligament of the cervical spine.Method:A total of 88 patients with K-negative ossification of posterior longitudinal ligament admitted to Nantong First People's Hospital from February 2017 to February 2022 were selected,they were divided into observation group(44 cases)and control group(44 cases)according to random number table method.The control group was treated with traditional anterior approach surgery,and the observation group was treated with posterior cervical enlarged spinal canal plasty.Operation time,hospital stay,neck disability index(NDI),Japanese orthopaedic association(JOA)score,and complications 2 months after operation were compared between the two groups.Result:Compared with the control group,the operation time and hospital stay in the observation group were shorter(P<0.05).NDI in both groups showed a decreasing trend 1 week and 2 months after operation,and NDI in the observation group were lower than those in the control group(P<0.05).JOA scores in both groups showed an increasing trend 1 week and 2 months after operation,and JOA scores in the observation group were higher than those in the control group(P<0.05).The complication rate of observation group was lower than that of control group(P<0.05).Conclusion:Posterior cervical enlarged spinal canal plasty in the treatment of K-negative ossification of the posterior longitudinal ligament of the cervical spine is beneficial to reduce the NDI,improve the JOA score and reduce the incidence of complications.
