1. Lumbar sympathectomy performed upon patients suffering from paralysis of the leg due to anterior poliomyelitis produces the same vascular changes that have been observed in normal patients,—viz., increased warmth and dryness of the foot due to vasodilatation and to paralysis of the sweat glands. The calorimetric readings indicate that sympathectomy causes considerable increase in the blood supply to the foot.
2. The vascular changes are of prolonged duration and perhaps are permanent.
3. It is possible to accelerate the rate of growth of a child's leg by the operation of lumbar sympathectomy.
4. The increase in comfort which results from transforming the cold, blue, damp foot of anterior poliomyelitis to one which is warm and dry is much appreciated by the patient.
