What is Thoracic Outlet Syndrome?
Thoracic outlet syndrome (TOS) is a group of disorders that occur when certain nerve or blood vessels are compressed. The compression of these structures occurs between the space of the first rib and clavicle (collarbone) and can cause pain or numbness into the neck, shoulder or down the arm into the fingers.
Types of Thoracic Outlet Syndrome
- Neurogenic. This is characterized when the brachial plexus, the bundle of nerves running across your upper chest, is compressed. This is the most common type of thoracic outlet syndrome, representing almost 95% of all thoracic outlet syndrome cases.
- Venous. This is the compression of the subclavian vein. More common in males than females, typically occurring in their 20’s or 30’s. More common in the dominant arm.
- Arterial. Compression of the subclavian artery. The most rare case, occurring in roughly 1% of all TOS cases. More common in females and those born with a cervical rib.
