Case Discussion
Cervicothoracic junction can be located based on the angulation of the transverse processes:
- C7 transverse processes point down
- T1 transverse process point up
Taking that rule into account, it can be observed that C7 has a small left rib and large right rib, and all the thoracic ribs are present except T12 left rib, which is absent. Note that hypoplastic T12 right rib is also seen.
