摘要:

背景:颈椎后纵韧带骨化是脊髓、神经根受压的原因之一,对于有神经症状的患者常需手术治疗,而影响后纵韧带骨化症修复效果的因素较多。
目的:观察颈椎后纵韧带骨化症患者的临床特征,评估影响修复效果的影响因素。
方法:对2008年9月至2014年6月收治并获得随访的64例颈椎后纵韧带骨化症患者进行回顾性分析,患者治疗前后的神经功能采用日本骨科协会评分(17分法)进行评估,治疗后神经功能恢复率结果分为4个等级:75%-100%优,50%-74%良,25%-49%可,0-24%差。对患者临床指标与治疗后恢复率的相关性进行Pearson相关性分析。
结果与结论:64例患者中步态不稳占41%。治疗前后日本骨科协会评分提高了(5.54±1.21)分(t=-34.68,P < 0.01),治疗后恢复率为(53.76±12.09)%。根据治疗后恢复率进行分级,优4例(6%),良39例(61%),可21例(33%),差0例。治疗前病程、步速、日本骨科协会评分、脊髓信号改变与颈椎后纵韧带骨化症术后疗效有显著相关性,且病程小于1年时术后优良率较高(P < 0.05),治疗前日本骨科协会评分低于4分术后优良率显著降低。患者的年龄、性别、病变节段、累及节段数、修复方式与术后疗效之间未见明显相关性。提示早期充分的手术减压能够有效促进颈椎后纵韧带骨化症患者脊髓神经功能症状的改善和恢复。

Abstract:

BACKGROUND: Ossification of the posterior longitudinal ligament is a cause for cervical spinal cord or nerve root compression. For patients with ossification of the posterior longitudinal ligament who have neurological symptoms, surgery is necessary. Various clinical factors influence the surgical outcome.
OBJECTIVE: To investigate the clinical characteristics and analyze the influencing factors of ossification of the posterior longitudinal ligaments of cervical vertebra.
METHODS: A retrospective analysis was performed in 64 cases of ossification of the posterior longitudinal ligaments of cervical vertebra, who underwent surgical treatments from September 2008 to June 2014. All the patients were successfully followed up. Japanese Orthopedic Association scores system (17-point method) was applied to evaluate the patients’ nerve functions. After treatment, results of the recovery rate of neurological functions contained four grades: 75%-100% excellent, 50%-74% good, 25%-49% average, and 0-24% poor. The correlation between patients’ clinical parameters and postoperative recovery rate was analyzed using Pearson correlation.
RESULTS AND CONCLUSION: Among 64 patients, instability of gait accounted for 41%. Postoperative Japanese Orthopedic Association scores was significantly elevated by (5.54±1.21) points (t=-34.68, P < 0.01). The postoperative recovery rate was (53.76±12.09)%. According to the efficacy, the patients with ossification of the posterior longitudinal ligaments of cervical vertebra were classified as 4 excellent (6%), 39 good (61%), 21 average (33%) and 0 poor. Preoperative course, gait, Japanese Orthopedic Association scores and intramedullary signal change were strongly associated with the efficacy of surgical treatment. The patients with symptoms’ duration less than one year had high excellent and good rate of surgeries for ossification of the posterior longitudinal ligaments of cervical vertebra (P < 0.05). The excellent and good rate was significantly decreased in patients with preoperative Japanese Orthopedic Association scores less than 4 points. Patients’ age, gender, location, the number of involved segments and repair method were not obviously correlated with the efficacy of surgery. These data indicated that early surgical decompression could effectively promote symptom alleviation and neurological recovery in patients with ossification of the posterior longitudinal ligaments of cervical vertebra.
