RESUMO
While free tissue transfer has long been established as a reliable microsurgical technique in the adult population, its application in pediatric reconstruction is a relatively recent phenomenon. Despite initial concerns regarding minute vessel diameters, increased propensity for vasospasm, and limited tissue availability, pediatric free tissue transfer is now a widely used technique that has demonstrated an acceptable level of donor and recipient site morbidity in children. Five flaps commonly used in the reconstruction of lower extremity trauma are discussed in this paper: the latissimus dorsi, rectus abdominis, anterolateral thigh, gracilis, and the subscapular and parascapular flaps. The indications, blood supply, advantages, and disadvantages of each are detailed. Incredible progress has been made in the application of microsurgical techniques to the pediatric population over the last several decades. With a healthy understanding of the anatomy and functionality of the donor site, the reconstructive surgeon can repair a variety of complex injuries with an acceptable morbidity and mortality rate.
