Cervical Rib

The occurrence of a cervical rib can cause a shape of thoracic outlet syndrome due to compression of the brachial plexus or subclavian artery. 

Cervical rib found in 0.5% of population and come out more frequently in women than in men. A cervical rib is an inborn abnormality condition, which means it is present at birth, though it is repeatedly not identify until adolescence or later when indicators and complications are more likely to arise.

This state is usually asymptomatic, meaning that there are no physical signs that it exists. Most people who have a cervical rib problem do not present any symptoms. In this situation, no cure is compulsory. Other patients begin to experience symptoms as they enter middle age, perhaps as a result of changes in posture and muscle tone.

The shoulders start to get loose in middle age, which causes the cervical rib to get dejected and thus compressing the vessels or nerve roots of the concerned region. For this reason, most cervical ribs are diagnosed in middle age; else they may remain asymptomatic and undiagnosed.
