First experience of application of modular endoprosthesis for treatment of bone sarcomas in the Federal Research Center of Pediatric Hematology, Oncology, and Immunology named after Dmitriy Rogachev

Abstract

At present, endoprosthesis of bones and joints with the use of modular oncology prosthesis is the most common method of organ-preserving treatment. Since the moment of opening of the FCRC of PHOI named after Dmitriy Rogachev, over 20 surgical operations for endoprosthesis replacement have been performed in the department of surgery of children and adolescents. MSTS (Musculoskeletal Tumor Society Score) international scale was used for assessment of the functional result after the surgical therapy. The worst result in accordance with the scale comprised 50 %, the best result comprised 93 %. The average index was 76 %. The possibility of the intra-operational varying of the replacement volume of the postresection defect is a good feature of modular endoprosthesis that saves the surgeon from possible errors of the pre-operational planning and unpleasant findings in the course of the operation. This simplified performance of endoprosthesis replacement in conditions of a small medical center with little clinical experience in this field, particularly in the course of performance of operations for children. Endoprosthesis secures good onclological and functional results as well as favors the most adequate social adaptation of a child.
