  • Radial head implant system including modular implant and modular radial head locking instrument
    Patent number: 6361563
    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.
    Type: Grant
    Filed: May 15, 2001
    Date of Patent: March 26, 2002
    Assignee: Wright Medical Technology, Inc.

  • Bone plating system
    Patent number: 6283969
    Abstract: 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 “snap-lock.
