Surgical screw and washer

Abstract

Abstract A surgical fastener for fixation of graft tendon (26) in a bone hole comprising a screw (10) having a head (11), neck (12), and shank (13), and a washer (17) disposed about the neck. The tendon (26) is attached to the washer (17) so as to ensure that the tendon (26) is immobilised between the head (11) of the screw (10) and the wall of the bone hole thereby reducing pistoning under load and reducing graft failure. In one embodiment, the fastener includes a bone plug (38) disposed about the neck (12) of the screw (10) between the head (11) and the washer (17), the neck (12) being adapted to laterally press the bone plug (38) and thereby immobilise a tendon (26) attached to the washer between the bone plug (38) and the wall of the bone hole. In another embodiment, the invention consists in a surgical staple (60) having two substantially parallel legs (61), a transverse head member (62) and a washer (66) which holds a loop of tendon (26) under the staple (60) when it is inserted into a bone.
