The medial gastrocnemius muscle flap: a local free flap

A new application of the medial gastrocnemius muscle flap has been described. Lengthening of the sural vascular pedicle was obtained using interposition vein grafts. This allowed coverage of a larger defect than that which could have been obtained with the tethered muscle and without further insult to the already disturbed lower extremity anatomy. The principle of pedicle lengthening can be used to increase the arc of rotation of various other muscle, myocutaneous, skin, or bone flaps and thereby increase their usefulness.
