Abstract

Superior Articular Facets are located on atlas vertebra facing supero medially & they occupy most of the upper surface of the lateral mass and lie obliquely, their anterior ends being always nearer to the midline than the posterior ends. Methodology: A total of 57 human dried atlas were taken from the dissection hall of anatomy department of, G.R. Medical College, Gwalior, M.P. for the evaluation of the superior articular facets on the atlas vertebrae, by using dry, bony and non-pathological vertebrae. Measurements were taken by using Digital Vernier calipers. Results: The mean value of superior articular facet atlas vertebra AP Diameter was 21.184 ± 2.23, Transverse Diameter was11.35 ± 2.03 on right side. The mean value of superior articular facet atlas vertebra AP Diameter was 21.058 ± 2.15, Transverse Diameter 11.018 ± 2.11on left side. Conclusion: These data may be of great help in Craniovertebral decompressive and stabilising surgery and anthropological assessments.
