颈椎横突孔的形态与颈椎病

<正> 前言颈椎病是指颈椎本身或其邻近的软组织急性损伤和慢性劳损所引起的压迫或刺激椎动脉、颈神经根、脊髓颈段和交感神经的一种综合病症。它属于常见病多发病。目前对于本病的发病机理的研究进展不快,意见也不统一。关于颈椎病的分型,现趋向于分为五种,即神经根型、椎动脉型、交感神经型、脊髓型和混合型。对于椎动脉型现一般认为,是由于椎体缘骨刺、椎间孔横径变小,刺激、压迫椎动脉或周围交感神经丛.而发生椎动脉痉挛,导致

THE MORPHOLOGY OF FORAMEN TRANSYERSARIUM OF CERVICAL YERTEBRAE AND CERVICAL SPONDYLOSIS

By means of photography and measuring with a sliding scale 1054 foramina in the transverse processin 545 cases of cervical vertebrae were studied. including the measurement of sagittal and trausvetse dimeter. Some typical morphological characteristics of the cervical spine were described in detail, eg. The sulcusof tbe A. vettebralis over the posterior arch of the atlas changed into a hole instead. In some instances,the foramina were abscent or smaller than usual in one side or both sides in the transverse process.Occasionally, the foramina were divided into two parts. forming a double holes in the transverse process.In others, the superior articular process became hypertrophied. growing forward and coveriug the foraminaof the transverse process. Based upon the statistical analysis of the morphological variations of the foramina A. vertebralis.the relationship between the morphology of the foramen of the cervical spine and the causing factors ofcervical spondylosis was disctissed.
