Hello!
Cervical rib is an additional rib which arises from the 7th cervical vertebra. It is usually attached to the 1st rib close to the insertion of the scaleneus anterior muscle and is present in less than 0.5 of the population.
It may be a complete rib but more often it is present as an extension on the front and back for a small distance only.
It is usually present on the right side and in few cases it is present on both sides.
In 90% of cases there are no symptoms and if you have any issues regarding pain and discomfort follow up with an orthopedician.
Take care!
