Lower extremity muscle perforator flaps for lower extremity reconstruction

A true muscle perforator flap is distinguished by the requisite intramuscular dissection of its musculocutaneous perforator to capture the same musculocutaneous territory but with total exclusion of the muscle, and thereby results in minimal Functional impairment. Adher- ing to this definition, several lower extremity donor sites now are available, each with specific attributes especially useful for cosideration in the treatment of lower extremity defects. In this author's experience over die past two decades, 20 lower extremity muscle perforator flaps rising multiple donor sites proved advantageous for lower extremity coverage problems as either a local pedicled flap or as a miscrosurgical tissue transfer. significant complications occurred in 30 percent of flaps (six of 20) in that further intervention was required. Venous insufficiency and bulkiness were found to be the major inherent short- comings. However, giant flaps, lengthy and large-caliber vascular pedicles, and the possibility for combined flaps were important assets. The choice of a lower extremity muscle perforator flap for lower extremity reconstruction limited the surgical intervention and morbidity to a single body region.
