Abstract

A bone-tendon-bone drill guide for use is guiding drilling to form a pair of transverse holes through a bone end of a bone-tendon-bone ligament graft to receive a suture or sutures threaded therethrough to form a suture sling or craddle supporting the bone end as the suture are pulled into a tunnel section of a straight that has been formed into a patient's bone. The drill guide includes a pair of scissor arms connected at a pivot that are formed to where moving of lower hand engaging portions of the arms together also moves upper ends of the arms together whereacross opposing jaws are maintained. The jaws each include curved surface therealong for engaging a bone end fitted therebetween and each preferably includes spikes that extend from a jaw face for engaging, to hold in place, the bone end as a drill is turned through straight drill guide holes formed through a jaw to form transverse holes through the bone end, with the drill to exit the bone end and pass through openings formed through the other jaw. To lock the jaws in place, the drill guide further includes a straight brace that is pivotally connected to the lower end of one scissoring arm to pivot an edge thereof into alignment with a single tooth that extends from the bottom end of the other scissoring arm, the straight brace including a series of teeth formed along its edge to engage the single tooth and is spring biased to urge the series of teeth against the single tooth, urging a meshing engagement therebetween.
