Fixation screw, graft ligament anchor assembly, and method for securing a graft ligament in a bone tunnel

Abstract

A fixation screw, graft ligament anchor assembly, and method for fastening a graft ligament in a bone tunnel. The screw comprises an elongated shank having a distal end and a proximal end, and a central axis extending from the distal end to the proximal end. Screw threads are disposed on the shank and extend from the distal end to the proximal end. The proximal end defines an end plane disposed transversely to the axis and at an angle thereto other than a normal angle.

         25 . A bone tunnel liner for lining the wall of a bone tunnel which is to have a graft ligament fastened therein, said bone tunnel liner comprising;
 a tube having a distal end and a proximal end, and a central axis extending from said distal end to said proximal end; and   screw threads disposed on said tube and extending from said distal end to said proximal end;   wherein said proximal end defines an end plane disposed transversely to the central axis and at an angle thereto other than a normal angle.
