Tissue Selective Ultrasonic Debridement with Cryopreserved Human Skin Allograft to Heal a Chronic Wound: A Case...

Tissue selective ultrasonic debridement is a new method of debriding chronic wounds that prepares the wound for advanced tissue application. This article presents the case of an 89-year-old woman with a chronic nonhealing wound to her lateral distal leg. The wound had a significant amount of biofilm and fibrous slough. Conservative treatment consisting of debridement and multilayer compression was attempted for 4 weeks. After 4 weeks, the patient was taken to the operating room for tissue selective ultrasonic debridement with placement of cryopreserved human skin allograft. With local wound care and multiple applications of graft, the chronic wound fully epithelialized. This study highlights the use of tissue selective ultrasonic debridement combined with cryopreserved human skin allograft to successfully heal a chronic wound. To our knowledge, this method of operative debridement and application of graft has not been documented in the literature.
