Free fillet flap application to cover forequarter or traumatic amputation of an upper extremity: A case report.

Reusing tissue of amputated or unsalvageable limbs to reconstruct soft tissue defects is one aspect of the "spare parts concept." Using a free fillet flap in such situations enables the successful formation of a proximal stump with the length needed to cover a large defect from forequarter amputation without risking additional donor-site morbidity. The use of free fillet flaps for reconstruction after forequarter and traumatic upper extremity amputations is illustrated here in a case report. A 41-year old patient required a forequarter amputation to resect a desmoid tumor, resulting in an extensive soft-tissue defect of the upper extremity. A free fillet flap of the amputated arm and an additional local epaulette flap were used to reconstruct the defect. At 9 months after the procedure, a satisfactory result with a very well healed flap was attained. Free fillet flaps can be used successfully for reconstruction of large upper extremity defects, without risking additional donor-site morbidity. © 2015 Wiley Periodicals, Inc.
