Human amniotic membrane (hAM) is a collagen-based extracellular matrix that facilitates regenerative wound care. hAM offers several advantageous properties that promote epithelial cell growth, granulation, and angiogenesis. This case report demonstrates how Vivex Cygnus Matrix (Vivex Biologics, Miami, FL, USA) amniotic membrane was used over four weeks to graft a traumatic index finger injury that occurred while fishing. Cygnus Matrix allograft was first placed 72 hours after the accident. Following graft placement, the patient noted an immediate relief in pain and was able to return to all normal daily work activities within 48 hours of graft placement. Granulation tissue appeared a few days later. A total of four grafts were placed over the course of four weeks starting on September 4th, 2023. Typically, acute traumatic wounds are managed with a regimen of irrigation, wound dressing, and debridement. In this unique case, a distal fingertip amputation was treated with Cygnus Matrix allograft. A single hAM was applied weekly over the course of four weeks. Complete reepithelization of the injury was achieved with minimal scar formation. This paper demonstrates the use of hAM in healing acute traumatic wounds as an effective alternative to other more traditional treatments such as skin grafting, surgical reimplantation, and composite grafting. Utilization of hAM in acute traumatic wounds has few research reports that assure that the applications have minimal drawbacks while at the same time promoting wound management and patient comfort.
