Radial head implant system including modular implant and modular radial head locking instrument

A modular radial head system comprising:

• (a) a modular implant for replacing the head of the proximal end of a radius and for articulating with the capitellum of a humerus;
• said implant including a modular head having a first lock member, and including a modular stem having a second lock member for coacting with said first lock member of said modular head to lock said modular head and said modular stem together;
• and
• (b) a modular radial head locking instrument for locking said modular head and said modular stem of said modular implant to one another;
• said modular radial head locking instrument including a first jaw, a second jaw, and a control mechanism for urging said first and second jaws together;
• said first jaw having a distal end adapted to engage a portion of said modular stem and having a proximal end;
• said second jaw having a distal end adapted to engage a portion of said modular head and having a proximal end;
• said control mechanism engaging said proximal ends of said first and second jaws to provide offset axial compression of said modular head and said modular stem.
