Thoracic outlet syndrome secondary to childhood poliomyelitis.

2 women with acute anterior poliomyelitis affecting the upper limb girdles in early childhood later developed thoracic outlet syndromes, 1 of them bilaterally. It is thought that the poliomyelitis was a contributory factor in each case by allowing undue descent of the shoulder girdles, although cervical ribs were also present in the second case. This association had not been recorded previously. Both patients obtained substantial relief from anterior scalenotomy, indicating that previous involvement of the shoulder girdle by poliomyelitis does not negate the efficacy of this operative procedure.
