摘要:

文题释义:
颈椎曲度:颈椎生理曲度的存在能稳定颈椎、保护脊髓。在退行性颈椎病中,因椎体、椎间盘等结构的退变,颈椎的前凸可逐渐变直,甚至反凸。
节段稳定:此处的节段稳定,指下颈椎区域的颈椎节段稳定情况,将椎间活动度即角位移>10°或椎体的水平位移>3 mm定义为退行性下颈椎不稳。

背景:在颈椎曲度变直或节段不稳相关退行性颈椎病中,由项韧带慢性损伤引起的项韧带骨化是非常常见的。

目的:探讨项韧带骨化与颈椎曲度及下颈椎节段稳定性之间的相关性。

方法:回顾性分析徐州医科大学附属医院脊柱外科2017-10-01/2018-10-31收治的退行性颈椎病患者109例,男61例,女48例,年龄30-81(55.8±11.1)岁。所有患者对试验方案均知情同意,且得到徐州医科大学附属医院伦理委员会批准。对患者颈椎摄片进行影像学观察,观察内容包括项韧带骨化的分布和骨化程度、颈椎生理曲度的改变、下颈椎节段稳定性;根据患者有无项韧带骨化分为2组,比较2组患者的性别、年龄、颈椎曲度、下颈椎节段稳定性情况;采用Pearson相关性分析探讨项韧带骨化程度和颈椎曲度、下颈椎稳定的关系;采用二元Logistic回归分析项韧带骨化发展的重要危险因素。

结果与结论:①109例退行性颈椎病患者中,项韧带骨化患者56例,骨化共累及83个颈椎节段,以C4-5(39.8%)和C5-6(42.2%)多见;②项韧带骨化组患者的年龄、颈椎曲度中C2-C7 Cobb角、Jackson生理应力曲线、下颈椎不稳的参数角位移和水平位移与无项韧带骨化组差异均有显著性意义(P < 0.05),项韧带骨化程度与角位移呈显著正相关(r=0.486,P < 0.05);③下颈椎不稳患者的项韧带骨化发生率明显增高(P < 0.05),下颈椎不稳参数角位移及年龄是项韧带骨化发展的重要危险因素;④提示项韧带骨化患者更容易出现颈椎曲度变直及下颈椎的节段不稳,尤以节段不稳为著,在诊断和治疗退行性颈椎病患者时,项韧带骨化的存在应引起相应重视。

Abstract:

BACKGROUND: In degenerative cervical spondylosis associated with cervical curvature straightening or segmental instability, ossification of the nuchal ligament caused by chronic injury of the nuchal ligament is very common.

OBJECTIVE: To investigate the correlation between ossification of the nuchal ligament and cervical curvature and segmental stability of the cervical spine. 

METHODS: Data of 109 patients with degenerative cervical spondylosis, who were treated in Department of Spinal Surgery of Affiliated Hospital of Xuzhou Medical University from October 1, 2017 to October 31, 2018, were retrospectively analyzed. There were 61 male patients and 48 female patients, who aged 30 to 81 years old at a mean age of (55.8±11.1) years. All patients signed the informed consent. This study was approved by the Ethics Committee of Affiliated Hospital of Xuzhou Medical University. The patients underwent the X-ray examinations of cervical spine. The imaging observation included the distribution and degree of ossification of the nuchal ligament and the change of cervical physiological curvature and segment stability. The patients were divided into ossification group and non-ossification group according to whether or not the patients had ossification of the nuchal ligament. Gender, age, cervical curvature and lower cervical stability were compared between the two groups. Pearson correlation analysis was used to compare the relationship between the degree of ossification of the nuchal ligament and cervical curvature and cervical stability. Binary Logistic regression analysis was applied to evaluate the significant risk factors for the development of ossification of the nuchal ligament.

RESULTS AND CONCLUSION: (1) Of 109 patients with degenerative cervical spondylosis, 56 patients with ossification of the nuchal ligament and ossification involved 83 cervical segments in ossification of the nuchal ligament patients, most of which were C4-5 (39.8%) and C5-6 (42.2%). (2) There was significant difference in age, C2-C7 Cobb angle, Jackson physiological stress curve, parameter angular displacement and horizontal displacement between the ossification group and non-ossification group (P< 0.05). The degree of ossification of the nuchal ligament was positively correlated with angular displacement (r=0.486, P < 0.05). (3) The incidence of ossification of the nuchal ligament was significantly higher in patients with lower cervical instability (P < 0.05). Age and lower cervical instability parameter angular displacement were significant risk factors for the development of ossification of the nuchal ligament. (4) Patients with ossification of the nuchal ligament are more likely to have cervical curvature straightening and lower cervical instability, especially in the segment instability. In the diagnosis and treatment of degenerative cervical spondylosis, the existence of ossification of the nuchal ligament causes corresponding attention.

Key words: ossification of the nuchal ligament, cervical spondylosis, cervical vertebral physiological curvature, lower cervical instability, ossification degree, relevance
