The aim of the study is the objective assessment of the effectiveness of a micro-fragmented dermal extract obtained with Rigenera™ technology (patented by Human Brain Wave) in promoting the wound healing process in an in-vivo homogeneous experimental human acute surgical wound model. The study includes 20 patients with 24 acute post-surgical soft tissue loss and a planned sequential two-stage repair with dermal substitute and autologous split-thickness skin graft. Each acute post-surgical soft tissue loss is randomized to be treated either with Integra® dermal substitute enriched with the autologous dermal micro-grafts obtained with Rigenera™ technology (group A - Rigenera™ protocol) or with Integra® dermal substitute only (group B - Control). The re-epithelialization rate in the wounds is assessed in both groups at 4 weeks through digital photography with the software Image J. The dermal cell suspension enrichment with the Rigenera™ technology is considered effective if the re-epithelialized area is higher than the 25% of the total wound surface as this threshold is considered far beyond the expected spontaneous re-epithelialization rate.
