It was previously designated as scalenus anticus, costoclavicular, hyperabduction, cervical rib, and first thoracic rib syndromes according to presumed etiologies. The various syndromes are similar, and the compression mechanism is often difficult to identify. Most compressive factors operate against an osseous structure, most commonly the first rib.2,3
