The thoracic outlet lies at the apex of the thorax and is traversed by the subclavian vessels and brachial plexus as they enter the upper extremity. It can be divided, conceptually, into three spaces from proximal to distal: the scalene triangle, costo-clavicular space and sub-pectoral space (lying under pectoralis minor). Thoracic outlet syndrome (TOS) is the result of compression of one or more of the neuromuscular structures at this site and is classified according to the structure being compressed as: neurogenic, arterial and venous. Neurogenic TOS remains by far the most common of these.
