Background: The cervical vertebrae are distinguished by the presence of a unique anatomical feature: the transverse foramen (TF) within the transverse processes. The TF is formed by the union of the transverse process vertebral element posteriorly and the remains of the cervical rib vertebral element anteriorly. Present study was conducted for morphometric evaluation of foramen transversarium of sub axial vertebrae. Materials and Methods: A total of 100 dry subaxial cervical vertebrae (C3-C7) were collected, comprising 200 foramen transversaria. The anteroposterior length, transverse length, and depth of the foramen transversarium were measured using a combination of instruments, including a double-tipped compass and a digital vernier caliper. Statistical analysis was performed using Student's t-test. Results: The dimensions of the foramen transversarium in subaxial vertebrae were measured and recorded. The transverse length, anteroposterior length, and depth of the foramen transversarium were found to be 6.67 ± 0.15 mm, 5.54 ± 0.22 mm, and 3.44 ± 0.09 mm, respectively, on the right side of typical cervical vertebrae. The seventh cervical vertebrae exhibited slightly different dimensions. The prevalence of unilateral double foramen transversarium was found to be 5.2%, while the prevalence of bilateral double foramen transversarium was significantly higher, at 7.8%. Conclusion: This study provides a comprehensive assessment of the morphometry of the foramen transversarium in subaxial cervical vertebrae. The results highlight significant variations in the dimensions of the foramen transversarium between typical cervical vertebrae and the seventh cervical vertebrae. The study also reveals a notable prevalence of double foramen transversarium. These findings have important implications for neurosurgeons, radiologists, and anatomists.
