A novel fixation system (5) for fixing a graft ligament (10) in a bone tunnel (15). The fixation system comprises an interference screw (100) comprising a body (105) having a distal end (110) and a proximal end (115), screw threads (120) extending longitudinally along the body, and a transversely-extending region (130) formed in the body for receiving a transverse pin therein, whereby to securely lock the interference screw (100), hence the graft ligament (10), to the bone. The present invention can also be applied to attach other objects to bone, e.g., a bone fragment to bone. |
