Ponticulus posticus on the Posterior Arch of Atlas, Prevalence Analysis in Asymptomatic Patients

The Ponticulus posticus is a bony bridge located in the posterior arch of the atlas in relation to the passage of the vertebral artery. Its presence has been associated with development of cervical pain and cerebrovascular disorders. The purpose of this study was to assess its prevalence in asymptom...
