摘要:
Apparatus for reconstructing a ligament, the apparatus comprising: a fixation device for maintaining a graft ligament in a bone hole, the fixation device comprising: a fixation screw comprising a body having screw threads formed thereon and a ligament spacer mounted to the fixation screw, the ligament spacer comprising a canted face disposed opposite the fixation screw such that when a graft ligament is disposed within a bone hole, the fixation screw and ligament spacer may be advanced into the bone hole alongside the graft ligament so that the fixation screw creates an interference fit between the graft ligament and the wall of the bone hole, and the ligament spacer creates an interference fit between the graft ligament and the wall of the bone hole, with the canted face of the ligament spacer being aligned with the adjacent surface of the bone.
