“…Our two cases show that, provided due technical precautions are taken, similarly beneficial results can be achieved by high cervical chordotomy for painful phantoms in the upper limb as have already been achieved by high thoracic chordotomy for painful phantoms in the lower limb. The past failures of high cervical chordotomy are responsible for the suggestion (White, 1944) that division of the spinothalamic tract within the medulla (Schwanz andO'Leary, 1941 and1942 j White, 1941) or even higher still in the midbrain (Walker, 1942) would prove after a trial to be preferable procedures. However, in none of the published reports of these operations does a sufficiently high, and yet complete, level of analgesia appear to have been obtained.…”
