Analysis of literature related to treatment of children with humeral condyle fracture (HCF) showed that in 15–51% of cases the outcomes were unsatisfactory. Material and methods. Treatment experience of 486 children with acute HCF fractures aged 1 to 16 years is presented. The diagnostic uses additional oblique projections and computed tomography to detect the degree of dislocation and fragment mobility alongside with standard ultrasound examinations. Patients were distributed as follows considering the degree of HCF bone fragment dislocation: 170 (35%) patients with 1 degree of dislocation and 117 (24%) patients with 2 degree of dislocation, whereas 199 (41%) patients had 3 degree dislocation. Results. The patients were operated using the developed tactical scheme based on the suggested classification. It took into account both the degree of dislocation and fragment mobility in 1 degree fractures. Remote results were examined in 321 (66%) patients within 1–15 years after the trauma: the results were excellent in 278 (87%) cases, good in 29 (%) cases and satisfactory in 13 (4%) cases. Conclusions. Treatment of children with humeral condyle fractures was based on the differentiated approach to selection of treatment method depending on dislocation degree and mobility of a distal bone fragment.
