[A man with a painful shoulder and numb hand].

A 57-year-old man suffered from an anterior luxation of the left shoulder with a dislocated fracture of the greater humeral tubercle after a fall. His left hand was cold, numb and no arterial pulsations could be detected. After shoulder reposition, the hand became warmer and the numbness disappeared. The next morning, pulsations of the hand were absent again. CT angiography showed a dissection of the axillary artery with thrombosis.
