External tibial mill guide and method of use

摘要

A cutting guide includes a jig assembly that is configured to attach to a second surface of a bone. The jig assembly includes a guide block that defines a jig recess and that is configured to be disposed adjacent to the first surface. Also, the cutting guide includes a tool support that is moveably coupled to the jig assembly, and the tool support is configured to couple to the cutting tool and moveably support the cutting tool on the jig assembly. Moreover, the cutting guide includes an adapter that is removably received within the jig recess to adapt a dimension of the jig recess according to a corresponding dimension of the pocket. The adapter includes at least one adapter surface that is configured to abut the guide portion of the cutting tool to thereby limit movement of the cutting portion relative to the first surface of the bone.
