Thoracic Outlet Syndrome 101

Did you know that Thoracic Outlet Syndrome (TOS) affects about 8% of the population?

It’s a condition where the nerves and blood vessels in the space between your neck and upper back get compressed.

This space, called the thoracic outlet, is located between the scapula (shoulder blade), clavicle (collarbone), and first rib. It contains important structures like nerves, veins, and arteries.

TOS is influenced by muscles such as the scalene and pectoralis minor muscles, which affect the movement of the bones in the thoracic outlet.

Understanding these structures helps us understand how TOS can impact the body.
