Vertical mid-vertebral angles (normal)

Case contributed by Dr Subash Thapa

Mid-sagittal MRI images of a control patient without lumbo-sacral transitional vertebra.

Note the two vertical mid-vertebral angles at the caudal segments:

  • caudal angle = 38.9°
  • cephalad angle = 18.5°

Diff-VMVA (caudal minus cephalad) = 20.4°

Case Discussion

Vertical mid-vertebral angle (VMVA) is greatest at the most caudal mobile segment of a lumbar vertebra in a normal individual and decrease progressively across the more cephalad adjacent segments as in the control patient without transitional vertebra 1.
