“…Moreira et al (2020) [ 26 ] showed that the parameters from C3 to C7 were similar to those previously reported, with a similar trend about FT dimensions.

“…Indeed, this artery proved to exhibit significant tortuosity in 73% of elderly subjects and could be responsible, at least in part, for significantly larger diameters of FT at the levels of C4 and C6. Moreira et al (2020) [26] showed that the parameters from C3 to C7 were similar to those previously reported, with a similar trend about FT dimensions. [9,14,15,27,28] Zibis et al (2016) [16] studying 700 cervical spine foramen (C1-C7) from angiographic CT images, reported the highest average anteroposterior diameter (APD) in the C6 (6.07 mm on the right and 6.27 mm on the left).…”

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.

“…This study stated that the highest anteroposterior (AP) diameter was seen at the C6 level, and the lateral diameter was at the highest C3 level. The highest value of the area of TF was at the C3 (27.55 mm 2 ) level in females and at the C6 level (29.48 mm 2 ) in males [17]. Another interesting finding is that all of the variables had higher values on the left side than on the right side, like the findings obtained by Kim et al [22].…”

“…We see a similar study by Moreira and Herrero on Brazilians [17] that used CT images from C3 to C7. This study stated that the highest anteroposterior (AP) diameter was seen at the C6 level, and the lateral diameter was at the highest C3 level.…”

Cervical vertebrae may exhibit the anomalous presence of a double transverse foramen (DTF) that may impact the anatomy of related structures that traverse the cervical region, such as the vertebral artery (VA). This retrospective anatomical study utilized CT angiography cervical scans to examine the prevalence of DTF, VA, and TF areas. The subjects were separated into two groups: normal TF (NTF group; 26 males and 21 females) and double TF (DTF group; 21 males and 24 females). The males presented significantly higher TF area values (30.31 ± 4.52 mm2) than the females (27.48 ± 1.69 mm2) in the NTF group (p = 0.006). The sex differences disappeared when a DTF was present (p = 0.662). There were no differences in the VA area values between the sexes in both the NTF and DTF groups (p = 0.184). No significant differences in the VA area values between males of the NTF and DTF groups (p = 0.485) were noted. The DTF subjects presented an increased VA/TF area ratio than the NTF subjects (p < 0.001). This study showed that DTF presence reduced the TF area. In contrast, the VA area did not change despite the decreasing TF area. This might be an anatomical risk for transient vertebrobasilar insufficiency in subjects with DTF, especially in females, because VA space in the TF is less in DTF subjects than in NTF subjects. This may lead to easy VA compression in DTF subjects following neck trauma.
