BACKGROUND Supracondylar fractures of humerus are the second most frequent type of fractures in children. OBJECTIVE To describe the results of the treatment, the patients according to age, sex, complications, and final results. METHODS A retrospective descriptive study was conducted in patients with supracondylar fractures of humerus during the years 2018-2019. Absolute frequencies and percentages were calculated. RESULTS Fractures were more frequent in males (69.6%) and in the age group of six to 10 years for both sexes. 60.8% of the fractures were treated with reduction plus internal fixation with Kirschner needles, in the group with internal fixation type IV predominates and in the group that does not need internal fixation predominate type I, the most frequent complication was the loss of reduction in the group that was not fixed with needles. Better results were obtained when the reduction was performed combined with internal fixation (91.2%). CONCLUSIONS Fractures predominated in the male sex and in the age group of six to 10 years, the reduction was more frequent more internal fixation with Kirschner needles, in the group with internal fixation predominates type IV, predominated the loss of reduction in the group that was not fixed with needles. Better results were obtained when reduction was performed combined with internal fixation.
