Thoracic Outlet Syndrome

Thoracic Outlet Syndrome

Thoracic Outlet Syndrome (pronunciation: thor-uh-sik out-let sin-drohm) is a group of disorders that occur when the blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) become compressed. This can cause pain in your shoulders and neck and numbness in your fingers.

Etymology

The term "Thoracic Outlet Syndrome" is derived from the anatomical region, the thoracic outlet, where the syndrome occurs. "Thoracic" is derived from the Greek word "thorax" which means chest, and "Outlet" refers to the exit path from the thoracic cavity to the upper extremity. "Syndrome" is derived from the Greek word "syndromē" which means concurrence of symptoms, signifying a condition characterized by a set of associated symptoms.

Symptoms

Common symptoms of Thoracic Outlet Syndrome include Neck pain, Shoulder pain, arm pain, numbness and tingling of the fingers, and impaired circulation to the extremities (causing discoloration). Often symptoms are reproduced when the arm is positioned above the shoulder or extended. Patients can have a wide spectrum of symptoms from mild and intermittent, to severe and constant. Pains can extend to the fingers and hands, causing weakness.

Causes

Thoracic Outlet Syndrome can result from Physical trauma (such as a car accident), repetitive injuries from job- or sports-related activities, certain anatomical defects (such as having an extra rib), and pregnancy.

Diagnosis

Diagnosis of Thoracic Outlet Syndrome can be complicated due to the variety of symptoms that can occur. Doctors may perform a physical exam, and use tests such as X-rays, MRI scans, and nerve conduction studies to confirm the diagnosis.

Treatment

Treatment for Thoracic Outlet Syndrome typically involves physical therapy and pain relief measures. Most people improve with these approaches. In some cases, however, your doctor may recommend surgery.
