Observational, anatomical, cadaveric study.
We anatomically investigated the fibrous connection between the cervical nerves and the zygapophysial joint capsules.
Cervical spondylotic radiculopathy is caused by the compression of the cervical nerves as the static factor and head and neck movements as the dynamic factor. To understand the dynamic pathology of cervical spondylotic radiculopathy, the anatomic relationship between the cervical nerves and the zygapophysial joints needs to be investigated in detail.
In 11 cadavers, we dissected both sides from the C5 to C7. For macroscopic examination, we observed structures connecting the cervical nerves and the zygapophysial joints in 18 cervical nerves from three cadavers. In 14 sides of eight cadavers, we histologically analyzed the fibrous structures and their attachments.
Macroscopically, the fibrous band connected the cranial surface of the cervical nerve to the lateral and inferior aspects of the transverse process. In four of 18 nerves, the fibrous bands were divided into two fascicles by loose connective tissues. In addition, the fibrous bands extended along the dorsal aspect of the posterior tubercle of the transverse process and attached to the zygapophysial joint capsule. Histologically, densely stained fibrous tissues overlaid the zygapophysial joint capsule and extended to the recess between the posterior tubercle and inferior articular process on the cranial vertebral body.
We macroscopically and histologically clarified the fibrous bands connecting the cervical nerve to the zygapophysial joint capsule. The fibrous bands may help clarify the pathology of cervical spondylotic radiculopathy associated with the zygapophysial joints as dynamic factors.Level of Evidence: N/A.
观察性、解剖学、尸体研究。
我们对颈椎神经与关节突关节囊之间的纤维连接进行解剖学研究。
颈椎病神经根病是由颈椎神经的静态压迫因素和头颈部运动的动态因素引起的。为了了解颈椎病神经根病的动态病理学，需要详细研究颈椎神经与关节突关节之间的解剖关系。
在 11 具尸体中，我们从 C5 到 C7 进行了双侧解剖。对于大体检查，我们观察了来自 3 具尸体的 18 个颈椎神经中连接颈椎神经和关节突关节的结构。在 8 具尸体的 14 侧，我们对纤维结构及其附着进行了组织学分析。
大体上，纤维带将颈椎神经的颅侧表面连接到横突的外侧和下侧。在 18 个神经中的 4 个中，纤维带被疏松结缔组织分成两个束。此外，纤维带沿横突后结节的背侧延伸，并附着在关节突关节囊上。组织学上，染色致密的纤维组织覆盖关节突关节囊，并延伸到颅椎体后结节和下关节突之间的凹陷处。
我们从大体和组织学上阐明了连接颈椎神经和关节突关节囊的纤维带。纤维带可能有助于阐明与关节突关节作为动态因素相关的颈椎病神经根病的病理学。
