Small Joint Fusion Plate and Cutting Block

Abstract

A method and one or more devices for a capitolunate fusion includes a cutting block for attaching to the capitate bone and for cutting the capitate and lunate bones to fit a corresponding plate. The cutting block is removed and a fusion plate is fixed to the capitate and lunate bone with the plate having a capitate section and a lunate section with the capitate section and lunate section of the plate in a generally perpendicular arrangement to allow optimal fusion of the capitate and lunate bones. Further devices include a three and four bone fusion cutting block and fusion plate.

We claim: 
     
         1 . A fixation plate kit for bone fusions in a wrist comprising:
 a cutting block having at least one hole for temporarily securing the cutting block to a capitate bone and a plurality of slits for providing access to the capitate bone and at least one additional wrist bone for cutting into the capitate bone or at least one additional wrist bone,   wherein the cutting block has a first portion and a second portion;   wherein a first slit in the first portion creates a first plane on the capitate bone;   wherein a second slit in the second portion creates a second plane on at least one additional bone; and   a fixation plate comprising an elongated plate having a first end and a second end;
 the first end having a first surface with at least one hole through the first end for securing the fixation plate to the capitate bone; and 
 the second end having a second surface extending from the first surface and forming an angle with the first surface; wherein the second surface has at least one hole through the second end for securing the second end of the fixation plate to at least one additional bone.
