Abstract
Objectives Craniovertebral junction (CVJ) is a unique, mobile and complicated component of our spine which necessitates specific study pertaining to its structure as well as pathologies. This study aims to report the normative data detailing the CVJ anatomy among the rural population of Central India which would help us in understanding the joint dynamics. Materials and Methods A retrospective observational study was undertaken in the Department of Neurosurgery and Radiology, Mahatma Gandhi Institute of Medical Sciences, Sewagram, Maharashtra, from December 2018 to May 2019. A total of 255 head injury patients with a normal CT brain cervical spine were included in this study. Anterior and posterior atlantodental interval (AADI/PADI), clivus length (CL), foramen magnum diameter (FMD), Boogards and basal angle (BOO & BA) were measured and analyzed. Statistical Analysis Statistical analysis was done using Microsoft Excel 2016. A web-based, open source application known as OpenEpi.com (version 3.01) was used for applying unpaired t -test. Results This study had a mean age of 42.9 years. The difference in mean value of AADI between male and female population was not found to be statistically significant, while in case of PADI, CL, FMD, BOO and BA, it was found to be significant ( p < 0.05). On comparison of cases with age 20 years and > 20 years, we found the difference in values of ADI, CL and FMD to be statistically significant ( p < 0.05). Conclusion Although there are some similarities, namely, AADI measurements as compared with other studies, there are differences in cutoff values of other parameters. Being a major draining reference center for rural population in India, this data can be extrapolated to a similar population for reference.
