Fully Synthetic Bioengineered Nanomedical Scaffold in Chronic Neuropathic Foot Ulcers.

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.
