Abstract：
Accurate and detailed spinal canal diameter transverse foraminal morphometry measurements are essential for understanding spinal column-related diseases and surgical planning, especially for transpedicular screw fixation. This is especially because lateral cervical radiographs do not provide accurate measurements. This retrospective study was conducted to measure the dimensions of the transverse foramen sagittal and transverse diameter (TFD), spinal canal diameter, the distance of the spinal canal from the transverse foramina at the C1 to C7 cervical level, and the anteroposterior and TFDs in the Turkish population. A total of 150 patients who underwent cervical spine computed tomographic imaging with a 1:1 gender ratio were enrolled in the study. The sagittal and TFDs of the spinal canal, the distance of the spinal canal from the transverse foramen, and anteroposterior and TFDs in both right and left sides for all cervical levels C1 to C7. Foramina transversal diameters were measured using imaging tools of the imaging software in the radiology unit. The mean age of the study group was 47.99 ± 18.65 (range, 18-80) years. The majority of the distances of the spinal canal from the transverse foramen and antero-posterior (AP) & transverse (T) diameters for cervical vertebrae were significantly higher in male patients (P < .05). However, between age groups, a few measurements were found significantly different. Some of the distances of the spinal canal from the transverse foramen were significantly higher on the right side whereas all AP & T diameters were significantly higher on the left side in both male and female patients (P < .05). Almost all measurements were significantly higher on the left side for younger patients (<65 years) whereas only AP & T diameters were significantly higher on the left side for older patients (>65 years) (P < .05). Computed tomographic imaging is better than conventional radiographs for the preoperative evaluation of the cervical spine and for a better understanding of cervical spine morphometry. Care must be taken during transpedicular screw fixation, especially in female subjects, more so at the C2, C4, and C6 levels due to decreased distance of the spinal canal from the transverse foramina.
摘要：
准确和详细的椎管直径横向椎间孔形态测量对于了解脊柱相关疾病和手术计划至关重要。特别是椎弓根螺钉固定。这尤其是因为颈椎侧位X线照片不能提供准确的测量。这项回顾性研究是为了测量横孔矢状和横径（TFD）的尺寸，椎管直径，椎管从C1到C7颈椎水平的横向孔的距离，以及土耳其人口中的前后和TFD。共有150例患者接受了1：1性别比例的颈椎计算机断层扫描成像。椎管的矢状和TFD，椎管与横孔的距离,以及所有宫颈水平C1至C7的左右两侧的前后和TFD。使用放射科中的成像软件的成像工具测量了孔的横向直径。研究组的平均年龄为47.99±18.65（范围，18-80）年。在男性患者中，椎管与颈椎的横向孔和前后（AP）和横向（T）直径的大部分距离明显较高（P<0.05）。然而,年龄组之间，一些测量结果发现明显不同。在男性和女性患者中，椎管与横孔的某些距离在右侧明显较高，而所有AP＆T直径在左侧明显较高（P<0.05）。年轻患者（<65岁）的左侧几乎所有测量值均显着升高，而老年患者（>65岁）的左侧仅AP＆T直径显着升高（P<0.05）。对于颈椎的术前评估和对颈椎形态的更好理解，计算机断层扫描成像优于常规X射线照相。经椎弓根螺钉固定期间必须小心，尤其是在女性科目中，由于椎管与横向孔的距离减小，在C2，C4和C6水平更是如此。
