Chronic wounds present a significant burden on the healthcare systems worldwide, requiring innovative approaches for effective management. They pose a significant clinical challenge, often characterized by delayed healing, infection, and impaired tissue regeneration. This chapter highlights cases showcasing the successful utilization of novel technologies in the treatment of chronic wounds. The first case demonstrates the application of Spincare®, an electrospinning technology, in promoting wound healing following delayed healing after split-thickness skin grafting in a foot injury. The second case illustrates the efficacy of Novosorb/BTM®, a biodegradable temporizing matrix, in managing necrotizing fasciitis secondary to a skin injury in the lower leg. The following two cases show examples for chronic and complicated wound situations being treated with a decellularized fish skin from the Atlantic cod (Kerecis®), promoting wound healing in supporting cellular and vascular ingrowth. Through the integration of advanced technologies, significant improvements in wound healing and patient outcomes were achieved. These cases underscore the importance of adopting innovative approaches in chronic wound care to address the complexities associated with wound management and patient outcomes.
