Variants of soft tissues flaps for restoration of the lower limb defects as one of the most complex sections of reconstructive oncosurgery. Analysis of literature

Among all medical and social problems, malignant formations occupy one of the leading positions. Mastering the sections of reconstructive and plastic surgery, as well as increasing opportunities in the field of traumatology, orthopedics and vascular surgery, enable oncologists to perform organ-preserving operations in many cases, including on the lower limb without compromising the radical nature of tumor removal. The article presents more than 25 different techniques for the use of free and displaced tissue flaps for the replacement of hip, shin and foot defects.According to the data of domestic and foreign authors, the incidence of complete and partial necrosis (10.3-13.5% and 3.7%) with free transplants is significantly higher than with non-free ones (2.5% to 7.8%). Indications for free tissue autotransplantation on the lower extremity are extensive (more than 200 cm² for the hip, 100-150 cm² for the shin, more than 30 cm² for the foot), defects as well as defects after removal of complex composite tissues. A wide range of reconstructive plastic surgery techniques and the possibilities of modern oncology make it possible to develop an optimal algorithm for choosing the method of integrated treatment to improve the quality of life of patients.
