AbstractIntroduction: Radial head fractures are common injuries comprising 1/3 of the fractures about the elbow. Displaced fractures should be treated surgically. Simple two/three part fractures can easily be handled by osteosynthesis, but comminuted fractures pose a major problem for reconstruction. Therefore, prosthetic replacement is recommended if stable reconstruction is impossible.
Objectives: The clinical, functional and radiographic results in patients treated with anatomic radial head arthroplasty for comminuted radial head fracture were studied and clinical indications & efficacy of the procedure reviewed.
Methods: From June 2021 to June 2022, 20 patients of comminuted radial head fractures were operated with radial head arthroplasty. Functional outcome was evaluated using DASH questionnaire and MEPS scoring system.
Results: Based on the Mayo Elbow Performance Score, excellent results were obtained in 15 (75%) patients, good in 3 (15%) and fair in 2 (10%) patients. The final elbow flexion-extension range of motion was of 112◦, with a mean flexion of 125◦. The final forearm rotational range of motion was 134◦with a mean pronation of 75◦and a mean supination of 70◦.There were no major complications such as infection, implant loosening, instability of the elbow.
Conclusion: The clinical outcome studies of metallic radial head arthroplasty systems indicate that radial head replacement is a reasonable option to offer patients with comminuted radial head fractures and complex elbow trauma. Moreover, it has proven effective in preserving elbow motion and maintaining the relative length of the radius
