Hanifi U, et. al - This study intended to investigate the functional and radiographic outcomes of patients with unreconstructable acute radial head fractures treated with a monoblock ultrahigh molecular weight polyethylene (UHMW-PE) radial head prosthesis (RHP). A total of 11 individuals (four female and seven male patients) with a mean follow-up of 18.5 mo were included. Primary endpoints included the Mayo Elbow Performance Score (MEPS) and the Disabilities of Arm, Shoulder, and Hand (DASH) score. Researchers investigated the latest follow-up physical examination and radiographs for loosening, subluxation, and dislocation. The results of this study indicated that radial head arthroplasty with a monoblock UHMW-PE RHP was found to be safe and effective at short-term follow-up for treating acute unreconstructable radial head fractures with satisfactory functional and radiographic outcomes.
