Understanding
Thoracic Outlet Syndrome:
What Is Thoracic Outlet Syndrome?
Thoracic Outlet Syndrome is a condition caused by compression of nerves, arteries, or veins in the thoracic outlet the narrow space between the collarbone (clavicle) and first rib. This compression disrupts normal nerve and blood flow from the neck to the arm, leading to pain, weakness, and neurological or vascular symptoms.
Thoracic Outlet Syndrome is often misdiagnosed or overlooked, making specialized evaluation and treatment essential.
