Thoracic Outlet Syndrome

Thoracic outlet syndrome is a condition where the nerves in the arm, the brachial plexus, are squashed between the collarbone (clavicle) and the first rib beneath. When the patient repetitively raises their arms up (as in hanging sheetrock on the ceiling) they can have numbness and nerve difficulties with their arms. That doesn’t mean an operation is indicated, however.

They can be instructed to change their job, and physical therapy can be effective. If the condition is severe it must be confirmed by doing what is called an Adson Maneuver. This involves raising your arm up in the air and all the way back to where the pulse to your wrist is cut off. The artery goes through the same area the nerves are going through and will be compressed by the squeezing action of those two bones. If this test is positive it does not necessarily mean that surgery is needed; many people can have a positive test without any symptoms.
