These photos are from 1993. Back then I ran a leg ulcer clinic patterned after the Duke Dermatologist Claude Burton, creator of the “Duke Boot.” That was a piece of Duoderm covered by an Unna’s boot. The clinic was very smelly but we had an 85% healing rate when I looked at over 300 consecutive patients. What do you think our venous ulcer healing rate is in 2014? Yes, it is still 85%.
