Abstract
A method for treating an articular fracture of a tibia using a tibia plate with an extension arm, including: making an incision to expose the tibia; reducing the articular fracture of the tibia; contouring the tibia plate to fit the tibia; preliminarily fixing the tibia plate to the tibia; placing a screw partially into the tibia through a lateral elongated hole in the tibia plate; applying compression between a plate screw hole in the extension arm and an anterior surface of the tibia; and placing additional plate screws in the tibia through additional screw holes in the tibia plate.
Claims21
A tibia plate for treating an articular fracture of a tibia, comprising:
- a head with a plurality of screw holes and guide holes wherein the head is configured to extend along an articular rim of the tibia;
- a body attached to the head configured to extend along a length of the tibia, including:
- a plurality of screw holes;
- a plurality of guide holes;
- and
- a lateral elongated hole that is elongated along a width of the body;
- and
- an extension arm including a screw hole configured to extend along the articular rim of the tibia and to engage a posterior of the tibia.
A tibia plate system for treating an articular fracture of a tibia, comprising:
- a tibia plate comprising:
- a head with a plurality of screw holes and guide holes wherein the head is configured to extend along an articular rim of the tibia;
- a body attached to the head configured to extend along a length of the tibia, including:
- a plurality of screw holes;
- a plurality of guide holes;
- and
- a lateral elongated hole that is elongated along a width of the body;
- an extension arm including a screw hole configured to extend along the articular rim of the tibia and to engage a posterior of the tibia;
- and
- a clamping tool configured to engage the screw hole in the extension arm and an anterior surface of the tibia comprising:
