Resurfacing a circumferentially degloved hand by using a full-thickness skin graft harvested from an avulsed skin flap.

Abstract

Twelve patients with circumferentially degloved hands were treated with full-thickness skin grafts harvested from defatted avulsed flaps. All injuries were industrial accidents caused by various roller machines, not crush injuries. Of these 12 patients, 9 patients were degloved from the wrist level and 3 patients were degloved from the forearm. There were 11 distally based skin flaps and one flap was completely detached. Four patients were avulsed distally to the mid palm, with volar neurovascular bundles damaged at the "fenestrae" of the palm, which resulted in devascularization of the involved fingers. Among them, distal fingers were successfully revascularized by microsurgical techniques in 3 patients. The full-thickness skin grafts were prepared from the attached, avulsed skin flap to avoid junctional hypertrophic scarring. The graft was then secured to its anatomic position with multiple skin staples to improve skin graft take. Initial take of the graft averaged 93% (range, 85%-100%). Compared with conventional methods, this approach provides a higher rate of skin take and better cosmetic and functional results.
