This can be accomplished by harvesting the medial sural artery perforator flap from the medial aspect of the upper calf. Based on the musculocutaneous perforator of the medial sural artery, this flap preserves the medial gastrocnemius muscle and avoids unnecessary flap bulkiness. Between January 2002 and February 2004, we used 2 variants of the free medial sural artery perforator flap for ankle and foot reconstruction in 13 patients (10 fasciocutaneous flaps and 3 adipofascial flaps). In these patients, skin defects were combined with bone, joint, or tendon exposure. The main advantage of this flap is that it provides a thin and pliable coverage to achieve better accuracy in the reconstructive site. Other advantages include maintaining the function of the medial gastrocnemius muscle, providing a long vascular pedicle, and avoiding the need to sacrifice major arteries of the leg. The main disadvantages are the tedious process of intramuscular retrograde dissection of the perforator and the unsightly skin graft over the medial calf. Thirteen free medial sural artery flaps were harvested from the proximal calf area and transferred for ankle and foot reconstruction, either as fasciocutaneous flaps or adipofascial flaps. Advantages included thin coverage, maintenance of gastrocnemius function, a long vascular pedicle, and preservation of major lower extremity arteries. © 2005 Lippincott Williams & Wilkins, Inc.
