Background: A radial head fracture is the bone injury that occurs to an adult elbow the most frequently. People between the ages of 20 and 60 years are most commonly affected by radial head fractures. Falling on an extended hand when the elbow is partially flexed and the forearm is pronated is the most common mechanism of injury. Objective: We aimed to evaluate the results of open reduction and internal fixation (ORIF) of type II Redial-Head fractures (Mason type II) in the adults. Patients & Methods: This prospective quasi-experimental study involved 20 patients with type II fractures of head radius in Department of Orthopedics, Faculty of Medicine, Assiut University through the period from December 2018 till May 2019.Results: Overall mean age was 31.9 ± 7.58 years old with male had predominance (60%). Up to 90% of patients had mini screws, while 5% had mini screws with mini plate and 5% had mini plate only. The overall mean length of stay was 2.2 ± 1.15 days. Majority of patients did not have post-operative complications (70%), while 25% had delayed rehabilitation and 5% had post interosseous nerve injury. According to Broberg and Morrey criteria, most of patient had excellent evaluation (65%), 30% had good and only 5% had fair evaluation. There was statistical significant difference between grades of evaluation by Broberg and Morrey criteria and post-operative complications (p=0.014) with higher complications among patients with fair/good evaluation (83.3%) versus 16.7% in patients with excellent evaluation. Conclusion:The most effective methods of therapy for type II fractures appear to be ORIF employing small screws and mini plates. Additionally, ORIF was linked to a greater satisfaction rating and fewer problems.
