ABSTRACT

Introduction:  The dimensions of superior articular facet of atlas are important in understanding kinematics of craniovertebral joint and also for any kind of surgery in this region. The aims of the present study are to report the metric parameters of superior articular facet and also to study the morphological variations in shape, constrictions and separation of facets.
Material and Methods: 50 adult human dry atlas vertebra from central India were studied.
Results: The anteroposterior diameter of superior articular facet was found to be 21.33mm 0n right side and 21.37mm on left side, the Transverse diameter was found to be 11.53mm on right side and 11.72mm on left side. Surface area of Superior articular facet was found to be 164.34mm on right side and       165.28mm on left side. Tendency of complete separation of the facets was seen in 2(4%) cases. Oval shape was found to be the dominant shape in 31(31%) cases followed by dumb-bell shape in 24(24%) cases, kidney shape in18(18%) cases and figure of 8 shape in 13(13%) cases.
Conclusion: The detail study of dimensions, shape , surface area of superior articular facet of atlas are useful in internal fixation techniques for craniovertebral junction abnormalities . The knowledge of the dimensions can help in safe planning of these surgeries. This study will be useful for the anatomists, forensic experts, physical anthropologists, radiologists, neurosurgeons, orthopedic surgeons.
Key words: Superior articular facet, Atlas vertebra, Transarticular screw.
