BACKGROUND/OBJECTIVES: One of the surgical interventions applied in the cervical region is the pedicle screw method. The cervical pedicle screw is stronger than any other screw method; however, use of the cervical pedicle screw is limited due to the variability in the anatomy of the cervical vertebrae and the risks to the neurological and vascular structures in this region. This study aimed to determine the morphological features of subaxial cervical vertebrae of the adult Turkish population and to provide guidance for the pedicle screwing method.
In our study, pedicle analyses were examined in the subaxial neck vertebrae of a total of 60 patients, 30 male and 30 female, using computed tomography images. In subaxial vertebrae (C3-C7), bilateral pedicle width, pedicle axis length, pedicle transverse angle, sagittal and transverse diameter of vertebral foramen, and the distance between two pedicles were measured.
Pedicle widths that did not fit the commonly used 3.5 mm pedicle screw were detected in both male and female patients. The mean bilateral pedicle width in male patients was found to be greater than in female patients. When the parameter results were compared according to the levels, it was found that the pedicle width, pedicle axis length, transverse diameter, and the distance between the two pedicles increased statistically significantly.
We think that the data obtained from the study will help determine the appropriate screwing (screw selection) in subaxial vertebra pedicle surgery and increase the success of the surgical procedure.
背景/目的：颈椎区域应用的外科手术干预方法之一是椎弓根螺钉技术。颈椎椎弓根螺钉比其他任何螺钉技术都更坚固；然而，由于颈椎解剖结构的变异性以及该区域神经和血管结构面临的风险，颈椎椎弓根螺钉的使用受到限制。本研究旨在确定成年土耳其人群下颈椎的形态学特征，并为椎弓根螺钉置入方法提供指导。
在我们的研究中，使用计算机断层扫描图像对总共60例患者（30例男性和30例女性）的下颈椎椎弓根进行分析。在下颈椎（C3 - C7）中，测量双侧椎弓根宽度、椎弓根轴长、椎弓根横角、椎孔的矢状径和横径以及两个椎弓根之间的距离。
在男性和女性患者中均检测到不符合常用3.5毫米椎弓根螺钉的椎弓根宽度。发现男性患者的平均双侧椎弓根宽度大于女性患者。根据节段比较参数结果时，发现椎弓根宽度、椎弓根轴长、横径以及两个椎弓根之间的距离在统计学上显著增加。
我们认为从该研究中获得的数据将有助于确定下颈椎椎弓根手术中合适的螺钉置入（螺钉选择）并提高手术成功率。
