Background:Craniovertebral junction (CVJ) surgery includes several decompressive and stabilising operations, including transarticular screw fixation of the atlas vertebra and axis vertebra (C1 and C2) and posterior screw placement on the lateral mass. These operations, in turn, usually target the C1, which is a critical component of the CVJ's bony architecture and is regularly targeted. This study will attempt to collect and offer anatomical data of the atlas, which may be necessary for planning a surgical approach and assessing C1 fractures, among other purposes. AIM: The present study was aimed at making the following observations; To observe and measure specimens of the atlas vertebra to obtain morphological parameters and the second objective was to provide anatomic data for planning of a surgical approach to the CVJ.
