The treatment of radial head fractures is challenging for the trauma surgeon due to the complex functional anatomy of the elbow. Satisfactory results can only be achieved if the function and stability of the humeroradial joint are entirely restored. Thus, depending on the fracture type, ranging from non-displaced Mason type I fractures to comminuted Mason type III fractures, an individual treatment concept has to be established. Treatment protocols range from conservative treatment with short-term cast immobilization to open reduction and internal fixation according to AO-principles or to the implantation of a radial head prosthesis. In case of severe comminution of the radial head, resection arthroplasty might be indicated.
