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.

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

A distal radial plate including a longitudinal segment having a proximal end and a distal end; a transverse segment having a lateral end and a medical end; the distal end of the longitudinal segment attached to the transverse segment intermediate the lateral and medial ends of the transverse segment to form a T-shape; the longitudinal segment having a plurality of spherically recessed holes and having a slot with a proximal end and a distal end; the distal end of the slot having a spherical recess; the proximal end of the slot having a beveled edge which converges distally with the spherical recess of the slot; the transverse segment having a plurality of spherically recessed holes. An extender seats in one of the holes in the transverse segment of the distal radial plate and provides an additional hole on the lateral side of the transverse segment of the plate. Buttress pins have specially formed collars to be secured to the distal radial plate via a &ldquo;snap-lock.&rdquo; A slotted-style distal radial plate bender has slots for receiving and bending both the transverse and longitudinal segments of the distal radial plate.

Bone plating system

A system including modular radial head implants, sizers for trial reduction of the joint, and instrumentation for preparing the radial head, implanting the sizers, assembling the implants.
