Background: The cervical vertebrae sharing one common characteristic feature of transverse foramen affecting each transverse process. Materials and Methods: A total of 782 cervical vertebrae (Typical-494 & Atypical-288) of unknown age and sex were analysed to see double transverse foramen collected from Anatomy Department, B.J. Medical College, Ahmedabad. Results: Out of 782 cervical vertebrae, the double transverse foramen were found in 70 (9%) vertebrae. Among those 70 cervical vertebrae, 47 (6%) vertebrae were typical and 23 (3%) were atypical cervical vertebrae. Out of 47 typical vertebrae 32 (4.1%) vertebrae presented unilateral double transverse foramen with 23 (3%) on right side and 9 (1.2%) on left side. 15 (2%) typical cervical vertebrae were noted with bilateral double transverse foramen. Among 23 atypical cervical vertebrae 4 (0.5%) atlas (C1) vertebrae were having unilateral double transverse foramen with 2 (0.3%) on right side and 2 (0.3%) on left side. There were no bilateral double transverse foramen on atlas vertebrae. 19 (2.4%) seventh cervical vertebrae (C7) showed double transverse foramen, among which 14 vertebrae were having unilateral double transverse foramen with 4 (0.5%) on right side and 10 (1.3%) on left side. Remaining 5 (0.6%) seventh cervical vertebrae presented bilateral double transverse foramen. No double transverse foramen were found on axis vertebrae (C2).
Conclusion: Presence of double transverse foramen in cervical vertebrae can lead to neurological and hearing disabilities as they are related with vertebral artery variations. The variation is important for neurosurgeons and radiologists and anatomists.
