Morphometric Analysis Of Dry Atlas Vertebrae In The Population Of Northern India

Morphometry Of Atlas Vertebrae In Northern Population

Abstract

Background: The atlas is atypical first cervical vertebra. It is located near the vital structures of life. It has many structural variations and many dimensional variations. The aim of this study was to understand various dimensions of the Atlas vertebra and its variations with effect on the related structures. Material And Methods: 50dryhuman Atlas vertebrae were studied from various colleges in Northern India. A digital vernier calliper with a resolution of 0.01mm was used for carrying out these measurements. Result: The mean inner and outer groove length observed in 100 vertebral artery grooves was 6.94mm ± 1.195mm and 11.40mm ± 1.905mm respectively. The observed anteroposterior diameter had a mean of 7.52mm±1.27mm on the right side and 7.59mm±1.49mm on the left side of the foramen transversarium. The mean width of the vertebral artery groove was 8.43±1.22mm and 8.68±1.35mm on the left and right respectively. Conclusion: This information for clinicians can help in preventing any damage while performing invasive procedures in this region. The variations in the atlas vertebra and its relations with other structuresfor example nerve roots and vertebral arteries become easy with the understanding of its morphometric and morphological analysis in this study.
