To improve the cognition about X-ray characteristics of nuchal ligament calcification, and discuss biomechanical properties.
From September 2008 to August 2009, the X-rays of 163 cases showed nuchal ligament calcification, which datas were analyzed. There were 91 males and 72 females, the age from 38 to 68 with an average of 53.6 years. And the number of calcification segment, related vertebral level, and vertebral hyperosteogeny, intervertebral space or intervertebral foramen stenosis, anterior or posterior longitudinal ligament calcification, cervical instability in the relative segment were observed.
One hundred forty-one patients occurred degeneration in the relative segment. The characteristics of X-ray: the multiple nuchal ligament calcification existed single segment and the C5,6 and C4,5 were readily occurred, which multiple related vertebral sclerotin, intervertebral space or intervertebral foramen, anterior or posterior longitudinal ligament occurred pathological changes, moreover, it was main segment of pathological changes. The X-rays of 93 cases showed vertebral hyperosteogeny 72 intervertebral space or intervertebral foramen stenosis, 49 anterior or posterior longitudinal ligament calcification, 66 cervical instability in the relative segment. The percentage was respectively 65.96%, 51.06%, 34.75%, 46.81%.
Cervical X-ray examination could discover characteristics of nuchal ligament calcification in the relative segment, also is helpful to diagnosis of cervical spondylosis.
提高对项韧带钙化X线特征的认识，并探讨其生物力学特性。
选取2008年9月至2009年8月间163例项韧带钙化的X线片进行分析。其中男性91例，女性72例，年龄38～68岁，平均53.6岁。观察钙化节段数、相关椎体节段、椎体骨质增生、椎间隙或椎间孔狭窄、前或后纵韧带钙化、相关节段颈椎不稳情况。
141例患者相关节段出现退变。X线特征：项韧带钙化多为单节段多发，好发于C5、6及C4、5节段，多伴有相关椎体骨质、椎间隙或椎间孔、前或后纵韧带出现病变，且为病变的主要节段。93例X线片表现椎体骨质增生72例，椎间隙或椎间孔狭窄49例，前或后纵韧带钙化例，相关节段颈椎不稳66例。百分比分别为65.96%、51.06%、34.75%、46.81%。
颈椎X线检查可发现相关节段项韧带钙化特征，对颈椎病诊断有帮助。
