A 65-year-old African American man with diabetes presented by ambulance to the emergency room in February of 1993 for the treatment of frostbite to the toes of his right foot. He had been requiring insulin for 15 years. The frostbite occurred while the patient was outdoors shoveling snow. He could not feel either of his feet at the time of presentation. The physical examination demonstrated a superficial degree of frostbite, excellent posterior tibial and dorsalis pedis pulses, and positive Tinel signs over the tibial nerve in the tarsal tunnel, the deep peroneal nerve at the dorsum of the foot, and a tender common peroneal nerve at the fibular neck.
