Degloving injuries are common in road traffic accidents, especially involving the lower limb. Determining the viability of an avulsed flap is often difficult during initial assessment. Early recognition of nonviable areas can aid in reducing the number of debridements, reducing the chances of infection and sepsis and, thus, reduce the hospital stay and aid in early recovery. Further, skin from such nonviable areas can be harvested as a skin graft for coverage of the defect before the avulsed flap becomes necrosed.1 There are few clinical methods to determine flap viability like assessment of bleeding and its color on needle prick, which may not be reliable and is subject to interobserver variability.
