During a posterior approach to the cervicothoracic junction, the surgeon must identify the vertebral level. The vertebra prominens, which is the most prominent spinous process palpable at the base of the neck, corresponds to which cervical vertebra?
- A C5
- B C6
- C T1
- D C7 ✓
Correct answer: D. C7
Explanation
The vertebra prominens is the spinous process of D7, which is the most prominent spinous process palpable at the base of the neck. D7 has a long, non-bifid spinous process (though in approximately 10% of individuals, D6 or T1 may be more prominent). T1 spinous process is also prominent but lies just below D7. This landmark is clinically important for counting vertebral levels during physical examination and surgical planning.
