Analyze the results of unipolar modular radial head arthroplasty in the treatment of complex fractures associated with elbow joint instability. MATERIAL AND METHOD: Retrospective design study of 44 patients, 17 men and 27 women with a mean age of 51 years (17-78) who suffered radial head fractures (Mason III) in the context of an unstable elbow injury. Mean follow-up was 21.2 months (12-60). Radial head replacement was performed with a unipolar modular prosthesis with a fixed stem (Ascension() Modular Radial Head [MRH]), associating repair of concomitant lesions. The Mayo scale Elbow Performance Score (MEPS) was used to perform the functional assessment. A radiological evaluation was performed at the last follow-up and the complications were recorded. RESULTS: Final arc of flexion-extension was 108° with an average of 135° of prono-Supination. At final follow-up, 82% of results were satisfactory according to the MEPS. The 40% of patients (17) had radiographic signs of lucencies around the stem, although most of them were asymptomatic. Two of them needed a second surgical procedure because of painful prosthetic loosening and further surgery was required for a prosthesis dislocation. DISCUSSION: Radial head implants are an adequate treatment option for restoring stability in complex radial head fractures. Modularity allows a wide range of size combination and helps to avoid overstuffing. Periprosthetic osteolysis could be associated with the presence of pain, so it is necessary to perform long-term studies to test the potential complications of this finding.
