Abstract

The present invention relates to a surgical chisel for removing a section of bone. The surgical chisel includes a body having a cannulation which extends from the distal end of the body through at least a portion of the body and is configured and dimensioned to receive a guide wire; and a blade attached to the distal end of the body and having a sharp edge for impacting bone. Introducing the guide wire into the cannulation guides the chisel to the section of bone to be removed. The present invention also relates to a method of removing a section of bone with a chisel. The method includes the steps of inserting a portion of a guide wire into a bone; guiding the chisel blade to the section of bone along the guide wire; and impacting the chisel blade into the bone to remove a section thereof.
