目的通过解剖学研究，描述项韧带与颈椎后硬脊膜和枕骨后外侧部分的连接，特别是枕下三角和上颈椎区的深部连接。设计对10具防腐尸体头颈部进行枕下和上颈区解剖，包括完整标本和矢状旁切片标本。结果在矢状旁切片中，项韧带与颈后硬脊膜之间存在连续性，后者从中线向硬脊膜方向延伸较深，但仅在第一和第二颈椎节段。项韧带也从两侧延伸至枕骨，直至枕骨和颞骨之间的缝线，向上接近下项线。结论本研究首次完整地描述了项韧带与颈椎后段硬脊膜和枕骨外侧面的关系。这对于理解颈椎的生物力学，特别是头部在矢状面或横断面上的旋转运动具有重要意义。这可能对颈源性头痛和影响颈椎的各种退行性疾病的手法治疗有影响。
OBJECTIVE To describe previously unrecorded attachments of the ligamentum nuchae to the cervical posterior spinal dura, and to posterolateral parts of the occipital bone in an anatomical study, with particular reference to the deep aspects of the suboccipital triangle and upper cervical region. DESIGN Dissections of 10 heads and necks from embalmed cadavers were made in the suboccipital and upper cervical region, either in whole specimens or in parasagitally sectioned specimens. RESULTS In parasagittally sectioned material, continuity was observed between the ligamentum nuchae and the posterior cervical spinal dura as the latter passed deeply from the midline toward the dura, but only at the first and second cervical vertebral levels. The ligamentum nuchae also passed bilaterally on to the occipital bone as far as the sutures between the occipital bone and the temporal bones, approaching the inferior nuchal line superiorly. CONCLUSION The present study is the first to describe the full morphology of the relationship between the ligamentum nuchae and the cervical posterior spinal dura and the lateral aspects of the occipital bone. This is of significance for understanding the biomechanics of the cervical spine, particularly rotational movements of the head in the sagittal or transverse planes. This may have implications in manipulative therapy for conditions as cervicogenic headache and for various degenerative disorders affecting the cervical spine.
