Introduction

Radial head and neck fractures represent a significant portion of elbow fractures in adults, particularly affecting younger patients due to falls onto outstretched hands. Surgical treatment is often necessary for displaced and comminuted fractures, especially those with associated ligamentous injuries. This study evaluates the long-term clinical, functional, and radiological outcomes of patients with Mason type III and IV radial head fractures managed through open reduction and internal fixation using plate and screw osteosynthesis, due to the unavailability of radial head prostheses.

Material and method

We retrospectively analyzed 28 patients with Mason type III or IV radial head fractures treated with open reduction and internal fixation (ORIF) between 2020 and 2024. Clinical assessments included the visual analog scale (VAS) for pain, Mayo Elbow Performance (MEP) Score, and Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) score, as well as measurements of elbow flexion, extension, supination, and pronation. Radiographic evaluations assessed fracture union, loss of reduction, implant breakage or loosening, avascular necrosis, radiographic arthritis, and heterotopic ossification.

Results

At a mean follow-up of 29.1 ± 20.1 months in 28 patients (16 M/12F; mean age 48.5 ± 12.6 years), mean elbow flexion was 120.4 ± 14.7, extension loss 10 ± 5.9, supination 68.9 ± 8.8°, and pronation 62.8 ± 7.1°, with mean VAS 2.3 ± 1.1, MEP Score 83.0 ± 8.9, and Quick-DASH 12.8 ± 7.6. Complete fracture union was achieved in 25 cases, partial union in 2, and asymptomatic nonunion in 1. Complications occurred in three patients (10%), including implant loosening, loss of reduction, heterotopic ossification, and avascular necrosis; two patients showed post-traumatic degenerative changes. One patient required K-wire removal due to migration and another underwent revision fixation with iliac crest bone graft for screw loosening/nonunion. No cases needed open arthrolysis or secondary radial head resection.

Conclusion

While osteosynthesis is effective in managing Mason type III and IV radial head fractures, having a radial head prosthesis available in the operating room can provide flexibility, especially in comminuted fractures, and potentially reduce the need for revision surgeries. These findings underscore the importance of adaptable surgical planning to improve outcomes in complex radial head fractures.
