Salvage of Complete Degloved Digits With Reversed Vascularized Pedicled Forearm Flap: A New Technique

Complete ring avulsion injury necessitates a difficult choice between microvascular repair and revision amputation. Microvascular repair is technically difficult and amputation may leave an unsatisfactory result. We describe an alternative method whereby a reverse radial forearm flap is wrapped around the complete degloved digit. This provides good quality cover to the whole volar, dorsum, and both sides of the finger. We performed 26 pedicle radial forearm flaps for 26 patients in the Hand and Reconstructive Microsurgery Unit, Sohag University Hospital, from 2001 to 2009. Indications included soft tissue coverage of the thumb (n = 8), ring finger (n = 11), index finger (n = 4), middle finger (n = 2), and little finger (n = 1). Finger salvage was successful in 96% of patients. There was complete loss of 1 flap and partial flap loss of a second. Finger range of motion was excellent in 18 fingers, good in 7, and fair in 1. Two donor sites were closed primarily; the rest were closed with split-thickness skin grafts. There were no reports of cold intolerance of the hand or dysesthesias in the superficial radial nerve or lateral antebrachial nerve distribution. (J Hand Surg 2012;37A:832-836.
