Abstract
A bone fusion apparatus and method for positioning over and attachment to a desired bone area which can provide for radial compression of bones, with particular suitability for wrist fusion by attachment to suitable bones such as, for example, a plurality of carpus area bones, with or without attachment to the radius bone and/or to one or more metacarpal bones. The bone fusion apparatus includes an annular plate having an outer side for at least partially contacting bone and an opposite inner side. The plate has a top outer edge of greatest diameter and a smaller diameter, bottom inner edge which defines an at least substantially central opening through the plate. The plate is substantially conical in shape such that the plate tapers outwardly from the inner edge of the plate to the outer edge of the plate. The plate defines a plurality of preferably countersunk holes therethrough between the inner edge and the outer edge, wherein each of the holes is adapted for receiving a bone fastener. Also provided is a bone burr and handle which can easily be utilized to precisely burr bone at a location where the bone fusion apparatus is to be placed in order for the bone fusion apparatus to precisely be positioned and affixed to bone as desired.
