Thoracic-Outlet Syndrome

Thoracic-outlet syndrome is compression of the brachial plexus and/or subclavian vessels as they pass through the thoracic outlet (cervical rib, scalene, costoclavicular, or hyperabduction). Clinical: neck/shoulder/arm pain and numbness in the ulnar distribution, arm weakness, and vascular symptoms (cold/pale arm), worse with arm elevation. Treatment: posture/physical therapy, activity modification; surgical decompression for progressive neurologic/vascular compression.

Common Symptoms

Neck/shoulder/arm pain; ulnar numbness; arm weakness; cold/pale arm; worse with arm elevation

Causes and Pathogenesis

Anatomic narrowing (cervical rib/scalene/costoclavicular/hyperabduction) compresses brachial plexus/subclavian vessels.

Treatment

Posture/PT; activity modification; surgical decompression if neurologic/vascular compression progressive

Preventive Measures

Posture correction; avoid arm elevation/heavy load; PT.
