Abstract

Objective: To evaluate the fracture characteristics and treatment outcomes of radial head fractures managed by open reduction and internal fixation (ORIF) in adult patients. Subjects and Methods: A descriptive retrospective–prospective study was conducted on 21 patients (aged 19–68 years) with Mason type II–IV radial head fractures who underwent ORIF at Hanoi Medical University Hospital from August 2023 to June 2025. Clinical data, X-ray, and CT findings, as well as functional outcomes, were collected and assessed using the Mayo Elbow Performance Index (MEPI) at 1, 3, and 6 months postoperatively. Results: Mason type III–IV fractures comprised the majority (76.2%), with comminuted fractures being most frequent (52.3%). Most patients were fixed using a mini T-plate (61.9%), with a mean operative time of 78.5 ± 15.2 minutes. After 6 months, 72.7% of patients achieved complete bone union; 81.8% reported no pain, had elbow motion >100°, stable joints, and over 90% regained independence in daily activities. At the final follow-up, 85.7% achieved solid bone union and 85.7% had good to excellent MEPI scores. No cases of infection, implant failure, or radial nerve palsy were recorded. Conclusion: Open reduction and internal fixation is an effective and safe method for treating radial head fractures, restoring anatomic structure, joint function, and daily activity.
