One in every 20 people have an extra rib.

Did you know that one in every 20 people is born with an extra rib? Yes, it’s true! While most individuals have 12 pairs of ribs, some individuals may have an additional rib, known as a cervical rib.

A cervical rib is an extra rib present in the neck region, specifically attached to the seventh cervical vertebra. It is considered a congenital anomaly that develops during the early stages of fetal development. This rib is often smaller than the other ribs and is usually not connected to the sternum or breastbone.

Having an extra rib might sound unusual, but it is generally harmless and goes unnoticed in many cases. However, in some instances, a cervical rib can cause health issues. It may compress nearby nerves or blood vessels, leading to discomfort, pain, or numbness in the arm and hand. This condition is called thoracic outlet syndrome (TOS).

TOS symptoms vary from person to person but can include tingling sensations, muscle weakness, or even a cold sensation in the affected arm. The severity of these symptoms depends on the size and position of the cervical rib. In some cases, surgery might be required to alleviate the discomfort caused by the compression.

It’s essential to note that having an extra rib does not automatically mean an individual will experience any health problems. Many people live with a cervical rib without ever knowing it, as they remain asymptomatic throughout their lives.

In conclusion, while having an extra rib is relatively uncommon, approximately one in every 20 people is born with this congenital variant. Although it may raise concerns in certain situations due to potential health implications, the majority of people with an extra rib lead normal and symptom-free lives. If you suspect any related symptoms, it’s essential to consult a healthcare professional for a proper diagnosis and guidance.
