The simple displaced fracture of the radial head and capitellum is generally managed by the open raduction and internal fixation. Several kinds of devices have been used for the internal fixation of the radial head and capitellum. The Herbert screw, originally developed for the internal fixation of the carpal scaphoid but has proved to be effective that its use has now been expanded to inculuded fixation of other small cancellous bone and intra-articular fractures.
