Introduction: Children and adolescents often sustain both-bone forearm fractures, which are common injuries.
Aim of the study: To investigate the efficacy of single-bone fixation of the radius versus the ulna in diaphyseal forearm fractures in children.
Subjects and Methods: There were 25 children with forearm both-bone fractures in a prospective cohort study. The ulnas of nine children (the ulnar cohort) and sixteen additional children (the radial cohort) were each treated with a single bone fixation utilizing an intramedullary flexible nail.
Results: Twenty-four children (nine (100%) from the ulnar cohort and fifteen (94%) from the radial cohort) had an excellent score, while a single one from the radial cohort lost about nine degrees of pronation and was given a good score. Only one case suffered from the delayed union of the ulna.
Conclusion: Both ulnar fixation and radial fixation had the same results in the treatment of both-bone fractures of the forearm of the children using single-bone fixation. They are reliable techniques with less operative time, excellent functional outcomes, a low rate of complications, and less radiation exposure.
