When Traditional Offloading is not an Option, Could an External Fixator be a Solution?: A Case Report

Offloading is a cornerstone in managing diabetic plantar foot ulcers; however, it often represents one of the most challenging aspects of treatment for clinician and patient alike. The authors present a case of a 61-year-old African American man with type 2 diabetes and a limb-threatening plantar foot ulcer that required aggressive wound and surgical management. Due to the heavy drainage and patient adherence issues, traditional offloading techniques such as total contact cast, DH Pressure Relief Walker (Össur, Foothill Ranch, CA), and wedge shoes, among others, were not viable options. Without offloading, healing will be difficult to achieve and will take a long time, carrying a higher risk of limb loss. The decision was made to apply an Ilizarov circular frame with footplate to facilitate offloading and weight bearing in tandem with negative pressure therapy. Although this is still considered an unusual use of this device, the results were positive and the wound progressed to complete reepithelialization.
