Le Mapihan M, Amsallem L, Ing D, et al. - This research was attempted to present the midterm results of such a prosthesis. Researchers conducted a retrospective study including the prostheses with bipolar design and short cemented stem (Evolutive ^TM ) used in our institution since 2008, with a minimum 2-year follow-up. They recorded demographic and epidemiologic data about the patients and fractures. They studied 56 implants with a mean follow-up of 64,9 months (range from 24 to 119). The data exhibited that when treating both isolated radial head fracture or complexes elbow injury, the short cemented stem bipolar radial head prosthesis presents clinical and functional results similar to other radial head prosthesis with a low incidence of elbow arthritis.
