vertebral vascular foramen

Vertebral vascular foramina, also known as Hahn canal or cleft, 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
