[edit] Discussion of Cervical rib

  • A cervical rib is a supernumerary or accessory rib arising from the seventh cervical vertebra.
  • Occurs in approximately 0.5% of the population
  • More common in females than in males


  • Although a cervical rib is usually asymptomatic, it is the most important anatomic rib variant from a clinical standpoint because it can cause thoracic outlet syndrome by compression of the brachial plexus or subclavian vessels.
