Definition

Thoracic outlet syndrome is a group of disorders that occur when the blood vessels or nerves in the thoracic outlet — the space between your collarbone (clavicle) and your first rib — become compressed. This can cause pain in your shoulders and neck and numbness in your fingers.

There are several subdivisions of thoracic outlet syndrome, depending on the cause. Sometimes, doctors can't determine the cause of thoracic outlet syndrome.

Treatment for thoracic outlet syndrome may involve physical therapy, medications, surgery and other approaches.
