Background: The cervical vertebrae are identified by the presence of foramen transversarium (FT) in the transverse processes. The present study was conducted to assess morphometry of foramen transversarium of sub axial vertebrae and its variations. Materials & Methods: 62 dry human adult cervical vertebrae consisting of 108 foramen transversaria were studied and the anteroposterior and transverse diameters of all the foramen transversaria were measured to determine the size of the foramen transversaria. The size of right and left sides were compared. The distance between medial margin of uncinate process to medial margin of foramen transversarium was also measured.
