Perifascial Areolar Tissue Transplantation for Covering Exposed Proximal Interphalangeal Joint After Electric Burn

Abstract

Soft tissue damage in electric burn injuries is often deep and may expose tendons, bones, or joints in the hand. Here, we present the case of a 76-year-old man treated using perifascial areolar tissue (PAT) transplantation for covering the proximal interphalangeal joint of the middle finger, which had been exposed because of an electric burn. Following ointment therapy, surgery was performed on day 34 postinjury when a deep ulcer with opening of the proximal interphalangeal joint was observed on the dorsum of the right middle finger. After resecting the cartilage of the proximal interphalangeal articular surface, two Kirschner wires were inserted, and arthrodesis was performed. PAT was harvested from the left inguinal region and applied to the joint exposed wound of the middle finger. Full-thickness skin graft was applied over it. Three months after surgery, the preserved middle finger could be used as a functional finger. PAT transplantation does not require microsurgery techniques, is simple and minimally invasive, and has a short treatment period, so it may be an effective option for treating wounds in which exposed ischemic tissue is present. Soft tissue damage in electric burn injuries is often deep and may expose tendons, bones, and joints in the hand, which is the most common affected site. Here, we report a case treated using perifascial areolar tissue (PAT) transplantation for covering the proximal interphalangeal joint of the middle finger, which had been exposed because of an electric burn.
