What is thoracic outlet syndrome?

Thoracic outlet syndrome is a condition where symptoms are produced in the neck, shoulder, and arm due to compression of the nerves and/or blood vessels that pass through the thoracic outlet (an opening between the neck and the armpit). The thoracic outlet is surrounded by muscle, bone, and other tissues. Any condition that results in enlargement or movement of the tissues near the thoracic outlet can cause thoracic outlet syndrome. These conditions include muscle enlargement (such as from weight lifting ), injuries, an extra rib from the neck at birth (cervical rib), weight gain, and poor posture.

What are symptoms of thoracic outlet syndrome?

Symptoms include neck, shoulder, and arm pain, tingling, burning, numbness, or 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 to severe. Pains can extend to the fingers and hands, causing weakness.

How is thoracic outlet diagnosed?

Thoracic outlet syndrome is usually diagnosed by the patient's history and physical examination, where the patient's pulse is taken and monitored for changes during various arm movements. Other terms for this condition include scalenus anticus syndrome, costoclavicular syndrome, hyperabduction syndrome, and cervical rib syndrome.

What is the treatment?

This condition responds very favorably to chiropractic adjustments to the neck and shoulder, stretches, exercises, and massage.
