颈椎后纵韧带骨化症前路手术的多因素分析

[目的]探讨影响颈椎后纵韧带骨化症前路手术疗效的相关因素。[方法]48例颈椎后纵韧带骨化症患者，行前路手术治疗，随访1～4年，平均2．1年。根据术后神经功能JOA评分改善率，将患者分为预后良好、预后不佳2组。采用多元Logistic回归分析患者年龄、性别、神经功能、症状持续时间、合并糖尿病、Pavlov值、椎管狭窄率、骨化物分型、CT双影征、脊髓高信号、手术范围以及骨化物处理对患者手术疗效的影响。[结果]骨化物的处理方式是影响患者疗效的唯一因素（P=0．0067）。[结论]前路手术彻底切除骨化之后纵韧带，对脊髓充分减压是前路手术治疗颈椎后纵韧带骨化症的关键。

Factors affecting prognosis of patients who underwent anterior decompression for cervical ossification of posterior longitudinal ligament: a multiple logistic regression analysis

[ Objective ] To discuss the prognostic factors for cervical OPLL treated by anterior decompression. [ Method ] A total of 48 patients with cervical OPLL, who underwent anterior decompression, were followed up for 1 - 4 years, with an average of 2. 1 years. The patients were classified into a good-prognosis group and a poor-prognosis group according to the JOA neruologic scoring system. Age, sex, JOA score, duration of symptoms, diabetes mellitus, Pavolv ratio, occupying rate, type of ossification, CT double-layer sign, hyperintense areas, level of segments, and treatment of ossification were testified using multiple logistic regression analysis. [ Result ] Treatment of ossification was the only statistically significant factor predicting clinical results in this study. [Conclusion] It is the most important to resect the ossification and decompress the spinal cord thoroughly in the process of antarior decompression for cervical OPLL.
