Distant pedicle flaps for soft tissue coverage of severely burned hands: an old idea revisited.

Burns to the hand that are complicated by exposure of bone, joint or tendon cannot be closed with conventional skin grafts and require flap procedures to prevent further damage. Local or regional flaps may be unavailable if electrical or blast trauma produces a large zone of injury, or when forearm burn injury extends beyond fascia. Free tissue transfer may not be tolerated by critically ill burn patients. In these circumstances, distant pedicle flaps are one option for safe and effective soft tissue coverage. Over a 5-year period, we have performed six distal pedicle flaps for coverage of exposed hand structures when local or free flaps were contraindicated or unavailable. The patients required an average of 4.5 surgical procedures to complete hand reconstruction and soft tissue coverage. Soft tissue coverage was completely successful in five patients and partially successful in one patient. Single stage local or free flaps remain the treatment of choice when burned hands cannot be covered with skin grafts. When these flap options are not available, distant pedicle flaps provide a safe alternative.
