- Cervical ribs
Cervical ribs are supernumerary or accessory ribs arising from the seventh cervical vertebra. They occur in ~0.5% of the population, are usually bilateral, but often asymmetric 2, and are more common in females.
Related pathology
Although cervical ribs are usually asymptomatic, they are the most important anatomic rib variant clinically, because they can cause thoracic outlet syndrome by compression of the brachial plexus or subclavian artery/vein.
