Description
Introduction: The anatomy of atlas vertebra shows extensive variability in form and size, and also undergoes many structural modifications it is located at point close to the vital centres of the medulla oblongata which can get compressed by a dislocation of the atlantoaxial joint or instability of the atlantoaxial joint. Atlas vertebra helps in complex biomechanical movements of the skull along with weight transmission of skull to spine. Recent developments in fixation technologies and minimally invasive surgical approaches have encouraged acquisition of knowledge of various dimensions of atlas vertebrae which is very important for the development of instrumentation related to atlas vertebrae. Material & Methods: In this study, total 120 dry, adult human atlas vertebrae of unknown age and sex were examined for shape, size and number of superior articular facets on each side, in various medical colleges of North India. All dimensions were measured in bilateral manner using Digital Vernier Calliper. Results: Different shapes of superior articular facets observed were oval‑shaped, kidney‑shaped, rectangular, comma‑shaped, 8‑shaped, irregular and two or three separate facets. Length and width of the facet were similar on two sides. Conclusion: The observations of present study helps in improving understanding of bony dimensions of superior articular facet of atlas vertebra which could facilitate diagnosis and preoperative planning of craniovertebral joint dysfunction.
