Gamma-irradiated human skin allograft: a potential treatment modality for lower extremity ulcers.

Gamma-irradiated human skin allograft consists of epidermis and dermis. Unlike bioengineered tissues which require cold storage and timely use once received from the manufacturer, gamma-irradiated human skin allograft can be stored for as long as 24 months at room temperature. This modality is applied in a fashion similar to that of bioengineered skin grafts. In this article, we present case studies with concise reviews of the available evidence to discuss the potential use of gamma-irradiated human skin allograft on wounds in the lower extremity.
