ABSTRACT:
A method and related instruments are provided for the preparation, stabilization and fusion of the middle and distal phalanx bones in the finger. The method includes the steps of cutting the head of the middle phalanx to form one side of a miter joint and drilling a guide bore through both bones. The adjacent end of the distal phalanx is smoothed using a rotary disk with a center guide post to create the opposing side of the miter joint. A fixation plate is secured to the top of the finger and includes a positioning tube that extends into the guide bore. A screw assembly extends through the tube and into the bones to provide a compressive force across the miter joint. The preferred apparatus includes a combination drill template/saw guide for drilling the guide bore and cutting the middle phalanx, a rotatable disk for smoothing the distal phalanx and a screw assembly having spirally expanding strands at its distal end for anchoring the assembly in the distal phalanx. A tool kit including these instruments is also provided.
