The gracilis free flap revisited: a review of 25 cases of transfer to traumatic extremity wounds.
Trauma to the extremities often results in a complex bony and soft-tissue injury requiring free flap reconstruction. Muscles from various body sites have been used in extremity reconstruction since the early 1970s. The gracilis muscle is usually not considered the first choice for free flap reconstruction of these defects. It is usually relegated to small defects or used to reanimate the face. Our purpose is to present our experience with the gracilis muscle as a first-choice flap in reconstruction of traumatic extremity defects. A retrospective review of all gracilis muscle free flap transfers for traumatic extremity wounds between 1988 and 1995 at the Naval Medical Center Portsmouth was performed. Twenty-five patients age 20 to 71 years (mean, 29.7 years) underwent 26 free flaps to the lower leg, ankle, foot, or forearm to cover traumatic wounds. Defects ranged in size from 3 x 3 cm (9 cm2) to 13 x 18 cm (234 cm2), with a mean of 75.5 cm2. There were no flap losses and all wounds healed. Nine patients experienced 11 complications, which consisted of minor wound separation (16%), wound infection (12%), partial or complete loss of split-thickness skin graft (8%), thrombosis of graft with successful revascularization (4%), and nonunion of an underlying fracture (4%). Our overall success rate for gracilis free flap reconstruction of traumatic wounds is 100%. The gracilis free muscle flap has become our first option for tissue coverage in traumatized extremities. It leaves minimal functional defect limited to the side of the primary injury and provides a good cosmetic result. It can cover large defects when the epimysium is cut, and allows an epidural block to be performed for sympathectomy effect and pain control in the affected extremity during the immediate postoperative period.
