Abstract
A bone punch for altering the cross-section of a tunnel formed in a bone, the punch having a punch body with a distal region, a proximal region, and a plurality of planar guide faces extending between the distal and proximal regions to define a polygon in cross-section. The distal region terminates in a narrowed leading end to facilitate entry into the pre-drilled tunnel. A shaft is connected to the proximal region to transmit a force to drive the punch body into the bone tunnel to alter the cross-section shape of the bone tunnel to match the polygonal cross-section of the punch body.
