Thoracic outlet anatomy

Thoracic outlet syndrome is a rare condition that occurs when there is compression of vessels and nerves in the area of the clavicle. This can happen when there is an extra cervical rib or because of a tight fibrous band that connects the spinal vertebra to the rib. There may be pain in the neck and shoulders, and numbness in the last 3 fingers and inner forearm. Thoracic outlet syndrome is usually treated with physical therapy which helps strengthen and straighten out the shoulders.
