Verification of Kimmerle's Anomaly by X-ray Methods of Research

Kimmerle's anomaly is a bony bridge over the posterior arch of the first cervical vertebra that forms a bony ring. The vertebral artery passes through the opening. This bone bridge could theoretically be an extravasal compression of the artery and disrupt the normal blood flow to the brain. Evaluating the data of X-ray methods, determine the frequency of occurrence and types of Kimmerle anomaly.
