Resolution of Non-Diabetic Intractable Wounds with Severe Comorbidities Using Autologous Micrografts

The wound healing process is a complex mechanism related to many factors, such as the patient’s comorbidity, blood flow, and nutritional status. This study aimed to retrospectively evaluate patients affected by various disease states and treated with Rigenera® technology, a standardized micrograft preparation system. A total of 8 patients were treated with a suspension of autologous micrografts obtained from mechanical disaggregation of small pieces of skin tissue. The micrografts suspension was applied alone to the wound or in combination with porcine collagen scaffolds directly onto the wound as described in the text. Across all cases, there was marked improvement in wound healing, with a mean healing time of 103 days and a reduction of the diameter of the wounds by 54%. Notably, the use of micrografts resulted in an overall higher quality of life for the patients. This simple and low-cost micrografting procedure that can promote wound healing of different kinds of chronic non-healing wounds and does not require postoperative rest.
