AbstractOne patient with systemic sclerosis with index fingertip necrosis and another with probable systemic sclerosis with index and middle fingertip impending necrosis were successfully treated with ultrasound-guided median nerve block application on the affected side. The nailfold temperatures of the affected fingers measured using thermography were below 25°C. Immediately after application, the temperature increased substantially. After repeated applications, the mean basal temperature on the affected side increased by 3.6°C in Case 1 and by 5.9°C in Case 2. Peripheral nerve block can be a basic treatment for fingertip necrosis. The thermographical observation of the extent and region in which the temperature increased is novel.
