Abstract

Background: The main goal in treating significantly displaced distal radius fractures in children is to restore wrist function, achieve a good cosmetic result, and reduce complications. The common treatment method is closed reduction and percutaneous pinning with Kirschner wires under fluoroscopic guidance. Objectives: 1. To describe the clinical and radiographic characteristics of distal radius fractures in children; 2. To evaluate treatment outcomes for closed distal radius fractures in children using closed reduction and percutaneous pinning with Kirschner wires under fluoroscopy. Materials and methods: A cross-sectional study was conducted on 40 pediatric patients under 16 years old with distal radius fractures, with or without associated distal ulnar fractures, underwent closed reduction and percutaneous pinning with Kirschner wires under fluoroscopy at Can Tho Children’s Hospital from August 2024 to February 2025. Results: The study included 40 patients. Mean age was 11.4 years, 85% were male, 15% female. Radiographs showed 77.5% metaphyseal fractures, 17.5% physeal fractures, and 5% Galeazzi fractures; 32.5% had associated ipsilateral ulnar fractures. Closed reduction with percutaneous pinning was successful in 97.5% of cases. Mean operative time was 30.5 ± 6.78 minutes using a single lateral Kirschner wire. All patients achieved solid union within 3 months. At 3-month follow-up, “Mayo Wrist Score” outcomes were excellent in 82.5% and good in 17.5%. Conclusions: Closed reduction and percutaneous Kirschner wire fixation under fluoroscopic guidance is a safe and minimally invasive method for treating closed distal radius fractures in children, achieving good functional and cosmetic outcomes at the wrist.
