title: [Endoprosthetics of the radial column after trauma].
abstract: Non-displaced fractures of the radius head are in most cases treated conservatively. Open reduction and anatomical internal fixation of displaced radius head fractures is the method of choice. In comminuted fractures of the radius head (Mason type III and type IV) replacement with a radius head prosthesis achieves joint stability and prevents secondary complications, such as valgus elbow deformity and proximal radial migration. Modern anatomically formed prostheses show promising results in the medium-term view. Typical complications after radius head replacement are limited range of motion in the elbow joint, arthritis of the capitulum and heterotopic ossifications. In cases of capitulum arthritis, capitulum prostheses were developed to resurface the lateral compartment of the elbow joint. Short-term results are encouraging with improvements in pain and range of movement.
