Acute headache attributed to whiplash in arcuate foramen and non-arcuate foramen subjects
European Spine Journal, 2016 To test the association between arcuate foramen (AF) in the first cervical vertebra with acute headache attributed to whiplash.Retrospective study of 128 patients that suffered a whiplash. The presence or absence of AF was recorded after a radiographic study, as well as the presence or absence of acute headache after the whiplash.The frequency of AF ...

Arcuate Foramen: Anatomy, Embryology, Nomenclature, Pathology, and Surgical Considerations
World Neurosurgery, 2018 The arcuate foramen is an anatomic variant that is thought to arise from ossification of the posterior atlanto-occipital membrane. Owing to potential entrapment of the vertebral artery segment that traverses the foramen, vertebrobasilar ischemia may occur, and the person may experience vertigo, headache, or neck pain.We reviewed the literature ...

The Decreasing Prevalence of the Arcuate Foramen
World Neurosurgery, 2018 The arcuate foramen (AF), or ponticulus posticus, is an anatomic variant of the first cervical vertebra that consists of a complete or partial osseous bridge over the groove for the vertebral artery and extends from the posterior aspect of the superior articular facet to the superior lateral border of the posterior arch. The AF has been associated with

Arcuate foramen: “Anatomical variation shape or adaptation legacy?”
Surgical and Radiologic Anatomy, 2019 The groove of the vertebral artery on the posterior arch of the atlas (sulcus arteriae vertebralis) may become a complete or partial osseous foramen: the arcuate foramen. The presence of a complete or partial arcuate foramen is a rare anatomical variant described in a minority of patients and it seems to be associated with vertigo, vertebro-basilar ...

World Neurosurgery, 2018 To date, no information about the cortical bone microstructural properties in atlas vertebrae with arcuate foramen has been reported. As a result, we aimed to test in an experimental model if there is a cortical bone thickening in an atlas vertebra which has an arcuate foramen that may play a protective role against bone fracture.We analyzed by means ...

Arcuate foramen: prevalence by age, gender, and degree of calcification
Orthodontics & Craniofacial Research, 2000The aim of the present study was to evaluate the prevalence of calcification of the oblique atlanto‐occipital ligaments (OAOLs, arcuate ligaments) relative to gender, age, and degree of calcification. Lateral cephalometric radiographs of 255 subjects presenting for orthodontic evaluation were reviewed.

Spine, 1992
The occurrence, varieties, and distribution by race and sex of the arcuate foramina observed in 1,000 consecutively seen cervical spine radiographs are reported. The complete foramen is significantly more common in males, without any racial predilection. The partial foramen is commonest in white females. The rate of occurrence seems independent of age.
