Thoracic outlet syndrome (TOS) remains a challenging, controversial, and often misunderstood and misdiagnosed upper extremity disorder. Although TOS symptoms can be initiated by compromise of both neural and vascular structures, over 90% of all TOS cases are of neurogenic origin. Optimum recognition, diagnosis, and management of neurogenic thoracic outlet syndrome (NTOS) must begin with an understanding of the underlying cause of the neural compression or tension.
Neurogenic thoracic outlet syndrome (NTOS) is a compromise of the brachial plexus, caused by anterior scalene musculature, congenital fibrosis, congenital abnormalities, such as the occurrence of a cervical rib, or a clavicular deformity.
