摘　　要：目的:提高对项韧带钙化X线特征的认识,探讨其生物力学特性。方法:自2008年9月至2009年8月,对163例颈椎X线显示项韧带钙化的患者进行影像学观察。其中男91例,女72例;年龄38～68岁,平均53.6岁。观察内容包括发生节段数、钙化发生的椎体水平,相对应节段的椎体骨质增生、椎间隙/椎间孔变窄、前后纵韧带钙化及椎体间位置失稳的情况。结果:163例患者X线观察发现相对应节段病变数为141例。颈椎X线特征性表现为:大多数项韧带钙化存在于1个节段(占63.12%),多发生在C5,6和C4,5水平,其相对应节段的椎体骨质、椎间隙/椎间孔、前后纵韧带、椎体间位置绝大部分出现病变,并且是最主要的病变节段。椎体骨质增生93例(占65.96%),椎间隙/椎间孔变窄72例(占51.06%),前后纵韧带钙化49例(占34.75%),椎体间位置失稳66例(占46.81%)。结论:颈椎X线检查不仅可以发现项韧带钙化及其相对应节段的特征性表现,并且有助于颈椎病变的定位诊断。Objective：To improve the cognition about X ray characteristics of nuchal ligament calcification,and discuss biomechanical properties. Methods：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 seg-ment were observed. Results：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 calci-fication,66 cervical instability in the relative segment. The percentage was respectively 65.96% ,51.06%,34.75%,46.81%. Conclusion：Cervical X ray examination could discover characteristics of nuchal ligament calcification in the relative segment, also is helpful to diagnosis of cervical spondylosis.
