ABSTRACT
INTRODUCTION: Chronic ulcerations on weightbearing surfaces of the lower extremities are uniquely challenging and can lead to complications such as infection or amputation. OBJECTIVE: This 3-patient case series of 4 chronic wounds of various etiologies outlines the use of a fully synthetic bioengineered nanomedical scaffold that exhibits durability and allows for cell migration and angiogenesis while resisting enzymatic degradation. MATERIALS AND METHODS: The nanomedical scaffold was rehydrated in sterile saline at room temperature for 3 to 5 minutes until translucent and pliable, then it was fenestrated with a scalpel. Following sharp debridement, it was affixed to the ulcer. A nonadherent dressing was applied, followed by applying a moist sterile dressing in a bolster fashion. RESULTS: All 4 ulcers reached the primary endpoints of granulation, as well as decreased wound size, using the nanomedical scaffold. CONCLUSIONS: The nanomedical scaffold successfully reduced the ulcer depths, stimulated granulation tissue while preventing necrosis, and helped the wounds remain infection free. The outcome of this case series suggests a fully synthetic bioengineered nanomedical scaffold can be used as an alternative to human or animal extracellular matrix in chronic, hard-to-heal neuropathic ulcers.
