Supernumerary rib

Supernumerary Rib

A Supernumerary Rib is an additional rib that develops in a human body beyond the usual number of 12 pairs. These extra ribs are relatively rare and can occur in various locations in the body. They are often asymptomatic but can sometimes cause discomfort or health issues.

Definition

A Supernumerary Rib is defined as an extra rib that forms in addition to the typical 24 ribs in a human body. These ribs can occur at either the cervical (neck) region, known as a Cervical Rib, or at the lumbar (lower back) region, known as a Lumbar Rib.

Causes

The exact cause of supernumerary ribs is not fully understood. However, it is believed to be due to genetic factors or environmental influences during embryonic development. Some studies suggest a link between supernumerary ribs and certain genetic disorders, such as Klippel-Feil Syndrome.

Symptoms and Diagnosis

Supernumerary ribs are often asymptomatic, meaning they do not cause any symptoms. However, in some cases, they can lead to discomfort or health issues, such as Thoracic Outlet Syndrome or Brachial Plexus Injury.

Diagnosis of a supernumerary rib is typically made through imaging studies, such as X-rays or CT scans.

Treatment

Treatment for supernumerary ribs depends on the symptoms and potential health issues they cause. If the rib is asymptomatic, no treatment may be necessary. However, if the rib causes discomfort or health issues, treatment options may include physical therapy, pain management, or surgical removal of the rib.
