为给颈椎弓根螺钉的设计和手术方法提供解剖学基础，采用测量方法对20例成人骨骼的颈。至胸1的椎弓根及其相关结构作了观测。椎弓很高为6．4±1.1～9.1±1．3mm；其原为3．6±1.8～7．2±1.3mm；长为9．6±1.4～15．1±1．2mm、根体长为25±1．1～30±1．9mm，椎弓根内倾角为26．2°±6．0°～46．0°±3．5°，体根柱角为90．7°±2．3°～105．6°±4．6°，PS值为0．5±0.4mm～4．4±1．2mm，PM值为0．8±0．2～7.4±1．2mm。颈椎弓根螺钉的直径以3.0mm以内较安全，其长度不宜短干15．1±1．2mm，不宜长于29．1±1．4mm。颈椎弓根入钉是位干关节突柱背面，可根据纵向的上关节突关节面最低点下方距离（PS值）和横向上关节突往外缘内侧距离（PM值）。在胸1此值为椎板外缘外侧距离）来确定。螺钉置入方向通过水平面上的内倾角和矢状面上的体根柱角确定。
To provide an anatomical basis for the design and operation of cervical pedicle screws, 20 adult bones of the neck were measured using a measurement method. Pedicle to the chest 1 and its related structures were observed. The height of the vertebral arch was 6.4 ± 1.1 ~ 9.1 ± 1.3mm; the original was 3.6 ± 1.8 ~ 7.2 ± 1.3mm; the length was 9.6 ± 1.4 ~ 15.1 ± 1.2mm Body length was 25 ± 1.1 ~ 30 ± 1.9mm, pedicle inclination was 26.2 ° ± 6.0 ° ~ 46.0 ° ± 3.5 °, body angle was 90.7 ° ± 2.3 ° ~ 105.6 ° ± 4.6 °, PS value of 0.5 ± 0.4mm ~ 4.4 ± 1.2mm, PM value of 0.8 ± 0.2 ~ 7.4 ± 1.2mm . Cervical pedicle screw diameter less than 3.0mm safer, its length should not short dry 15.1 ± 1.2mm, should not be longer than 29.1 ± 1.4mm. Cervical pedicle screw into the nail is the back of the stem, which can be based on the longitudinal distance between the lower surface of the superior articular surface (PS value) and lateral articular process to the medial margin (PM value). In the chest 1 this value for the lateral lamina outer edge distance) to determine. The direction of insertion of the screw is determined by the camber on the horizontal plane and the angle at the sagittal plane.
