Thoracic-outlet syndrome, also known as upper thoracic outlet syndrome, is defined as an anatomical narrowing of the upper thoracic opening in the region between the collarbone and the upper rib. The causes are:

  • Cervical rib
  • Scalenus-anterior syndrome (narrow scalenus muscle triangle)
  • Costoclavicular syndrome (tightness between the 1st rib and clavicle in abduction of the arm)
  • Hyperabduction syndrome (tendon of the minor pectoralis tendon leads to compression of the vascular nerve sheath during abduction)
  • Callus formation after clavicle fracture.
