Abstract

The objective: аnalysis of complications after endoprosthetic reconstruction in children and adolescents according to the Henderson classification of failure of limb salvage surgery modified by the International Society of Limb Salvage committee (ISOLS).

Materials and methods.This study evaluates complications rates and mode of failures after endoprosthetic reconstruction for the tumor around the knee in 97 patients treated from 2012 to 2018 in D. Rogachev National Medical Research Center of Pediatric Hematology, Oncology, Immunology.

Results. Overall 19,6 % of failures were identified. The most common postoperative complications were structural failu res, infection and soft-tissue failure (6,19; 5,15 and 3,1 % respectively). None of the developed failures affected the timing of treatment protocol.

Conclusion. Literature review and the study results demonstrate that higher risk of failure in the paediatric group of patients is attributed to deficiency of adjacent soft-tissue and bone, skeletal immaturity, using of expandable endoprostheses and increased patient activity at this age. Multicenter studies are needed to optimize prevention and management of failures after endoprosthetic reconstruction.
