Abstract

A modular radial head system including a modular implant for replacing the head of the proximal end of a radius and for articulating with the capitellum of a humerus. The modular implant includes a modular head and an modular stem. The system further includes a modular radial head locking instrument for locking the modular head and the modular stem of the modular implant to one another. The locking instrument includes a first jaw, a second jaw, and a control mechanism for urging the first and second jaws together to provide offset axial compression of the modular head and the modular stem of the modular implant.
