Summary Severance of the tendo‐calcaneus or division of the sciatic nerve caused ulcers to appear on the heels of mice within 6 hr. of operation. This was due to thrombosis of capillaries in the subcutaneous tissues, resulting from a disorder of posture. The lumen of the capillaries was filled with a thrombus of platelets and lysed red cells. The endothelial cells were contracted and separated from one another. Division of sensory nerves did not cause ulceration, nor did division of the sciatic nerve alter ulcers due to tenotomy. It was concluded that nerves did not serve a trophic function. The relation of these ulcers to decubitae and the plantar ulcers of leprosy is discussed.
