Wrist fusion plate
First Claim
1. A method of fusing a wrist using a wrist fusion plate configured to extend over a carpus area and position at least one metacarpal relative to a radius, said method comprising:
- attaching a proximal end of said plate to the radius;
attaching a distal end of said plate to one of the metacarpals;
placing a saddle portion interconnecting said proximal end with said distal end over the carpus area; and
attaching said saddle portion to greater than one carpus area bone with at least three screws.

Abstract
The invention is directed to a wrist fusion plate 10 configured to extend over a carpus area and position at least one metacarpal relative to a radius. The wrist fusion plate includes a saddle portion 36 which is placed over the carpus area. A proximal end 38 extending from the saddle portion and attachable to the radius defines a first longitudinal axis. A distal end 40 extending from the saddle portion and attachable to one of the metacarpals defines a second longitudinal axis. The second longitudinal axis is not axially aligned relative to the first longitudinal axis in a medial-lateral direction.
