Role of Plastic Surgery in the Treatment of Pelvic Tumors

The principal goal of the surgical treatment of primary pelvic tumor is to obtain a free margin resection, facing the reconstructive surgeon to large soft-tissue defects. A concomitant one-step autologous reconstruction has been proved to lead to better results than delayed strategies, especially when radiotherapy or infections compromise the donor site. The reconstruction of periacetabular and sacral defects, after pelvic tumor resection, are charged by a high rate of complications and dissatisfying mechanical and nonmechanical results, and a successful reconstruction has been proven to improve the quality of life of the patients. The purpose of this chapter is to provide an overview of the most used reconstructive techniques, including internal hemipelvectomies, hindquarter amputations, and hip disarticulation, which are still performed, following bone tumor resection in the pelvic district.
