In this lecture, Dr. Kim uses evidence-based medicine to address the role of equinus in plantar ulcerations of the forefoot in Diabetic patients. He explains how equinus has been shown to cause increased plantar peak pressures, and how reducing this pressure may help ulcers heal. Dr. Kim then offers evidence challenging the role Tendo-achilles lengthening may play in treating these patients. Finally, he explains his research on shearing forces and its etiological affect in plantar ulcerations.
