Abstract:
1. A bone punch system, comprising: an instrument component including an elongate body and a punch extending from said elongate body, said instrument component defining a proximal component opening, a distal component opening, and a component passage extending therebetween, and said punch being configured to form a cavity in a bone in the shape of a stem portion of an implant; a guide wire extending through said proximal component opening, said distal component opening, and said component passage; and a stop having a base portion, a pilot portion and a collar interposed therebetween, said collar extending radially outward from said base portion, and said stop defining a proximal stop opening, a distal stop opening, and a stop passage extending therebetween, and further said instrument component extending through said proximal stop opening, said distal stop opening, and said stop passage, wherein said instrument component is axially movable relative to said stop between a first relative axial position and a second relative axial position, wherein said instrument component has an axially extending slot defined therein, wherein said stop includes a pin at least partially located within said axially extending slot, and wherein said pin cooperates with said slot to limit axial movement of said instrument component relative to said stop.
