Abstract

Diabetic foot wounds (DFW) are notoriously difficult to treat owing to poor vascularity, delayed healing and higher rates of infection. Human-derived acellular dermal matrices (ADM) have been used in DFW treatment, utilizing a matrix scaffold for new tissue generation. We investigate the efficacy of a micronized injectable human-derived ADM in the treatment of DFW. We retrospectively recruited 13 patients with diabetic foot wounds. Wounds were adequately debrided, and a micronized injectable ADM was applied. Wound sizes were recorded prior to treatment, at 2 and 4 weeks post-treatment. The mean defect of wounds treated was 19.21 cm. Our results showed a statistically significant reduction in wound size of 45% and 59% at 2 and 4 weeks post-treatment, respectively (p < 0.01). ADM was also effective in infected DFW as 84% of our wounds had positive tissue cultures at the time of application. Micronized injectable ADM has proven to be an effective treatment for DFW. Advantages include a ready-to-use injectable, single-stage treatment, minimal pain, mouldable matrix to fit any wound shape, allows for outpatient treatment and simple wound dressings.
