cervical rib

A unilateral or bilateral congenital anomaly of the 1st thoracic rib or 7th cervical rib, affecting up to 0.5–1% of the population, 15% of whom have an associated thoracic outlet syndrome due to associated neural and arterial defects. Cervical ribs range from type I, a short bar extending from the transverse process, to type IV, a complete extra rib articulating with the sternum.
