Use of an arterialized venous flap for resurfacing a circumferential soft tissue defect of a digit.

Abstract

Circumferential defects of digit are uncommon but present a challenging problem to the clinician. The use of simple skin grafts tends to cause tendon adhesions and can limit digital range of motion. The use of local skin flaps, such as a cross-finger flap, is limited by the considerable skin loss in a defect that is circumferential in nature. Other options have included the use of reversed forearm flap or some free tissue transfer. We report a case in which the circumferential defect of an index finger, measuring 6 cm around the digit and 3 cm long, is resurfaced by the use of a free arterialized venous flap raised from the volar forearm skin.
