Vertebral vascular foramen

Dr Henry Knipe and Dr Ayush Goel et al.

Vertebral vascular foramina are normal findings seen on cross-sectional imaging and should not be mistaken for a fracture, especially in the setting of trauma.

They transmit:

  • basivertebral veins (forms Hahn's canal): foramen is seen on the posterior surface of the vertebral body in the midline
  • intraosseous nutrient arteries: foramen usually seen anterolaterally
