The arcuate foramen. Variability in distribution related to race and sex.
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.
