Abstract:
1. A method for reconstructing a ligament, the method comprising: providing an apparatus for reconstructing a ligament, the apparatus comprising: a first fixation device for maintaining a graft ligament in a first bone hole, the first fixation device comprising: a first fixation screw comprising a body having screw threads formed thereon; and a first ligament spacer mounted to the first fixation screw, the first ligament spacer comprising a first canted face disposed opposite the first fixation screw; and a second fixation device for maintaining the graft ligament in a second bone hole, the second fixation device comprising: a second fixation screw comprising a body having screw threads formed thereon; and a second ligament spacer mounted to the second fixation screw, the second ligament spacer comprising a second canted face disposed opposite the second fixation screw; forming a first bone hole in a first bone, the first bone hole extending through the first bone so that one end of the first bone hole terminates at a first joint surface; forming a second bone hole in a second bone, the second bone hole extending through the second bone so that one end of the second bone hole terminates at a second joint surface; extending a graft ligament along the first bone hole and along the second bone hole; advancing the first fixation device into the first bone hole alongside the graft ligament so that the first fixation screw creates an interference fit between the graft ligament and the wall of the first bone hole, and the first ligament spacer creates an interference fit between the graft ligament and the wall of the first bone hole, with the first canted face of the first ligament spacer being positioned flush with the end of the first bone hole terminating at the first joint surface; advancing the second fixation device into the second bone hole alongside the graft ligament so that the second fixation screw creates an interference fit between the graft ligament and the wall of the second bone hole, and the second ligament spacer creates an interference fit between the graft ligament and the wall of the second bone hole, with the second canted face of the second ligament spacer being positioned flush with the end of the second bone hole terminating at the second joint surface.
