Abstract
This prospective case series evaluated the clinical outcomes of skin micro-fragment therapy in managing hard-to-heal diabetic foot ulcers (DFU). A total of ten patients with chronic DFU, who were treated in a specialized diabetic foot unit, were included in this study. The primary outcome was the wound healing rate at 12 weeks. Secondary outcomes comprised the time to complete epithelialization, wound area reduction (WAR) at 4 and 12 weeks, and the incidence of adverse events. After treatment with hy-tissue micrograft (HT-MG), 6 (60%) of patients achieved complete wound closure within 12 weeks. The mean healing time was 7.8 ± 2.4 weeks. The mean WAR at 4 and 12 weeks was 67.2% ± 23.5% and 87.5% ± 24% respectively. The procedure was well tolerated with no complications observed in the donor site such as pain or infection. No adverse effects related to the infiltration procedure at wound site were recorded with a promising wound healing rate during the follow-up period. These results suggest that HT-MG could be a safe and effective treatment option for chronic DFU, promoting noteworthy wound healing and reducing healing times. Further studies are required to confirm these findings and assess long-term outcomes.
