Abstract
The present disclosure relates to an expandable fastener for orthopaedic applications. The fastener is arranged for fastening when positioned in a bore hole in bone and comprises a body having an axis. The fastener further comprises an expansion portion moveable between a contracted configuration and an expanded configuration and arranged such that the expansion portion urges outwardly from the axis of the body towards the bone surrounding the bore hole when moving towards the expanded configuration. In addition, the fastener comprises a coupling member for coupling to the expansion portion. The coupling member is moveable along the axis of the body. The fastener also comprises an actuator movable along the axis of the body and arranged to move the coupling member along the axis of the body. One of the coupling member and the expansion portion comprises a recess and the other one of the coupling member and the expansion portion comprises a projection. The projection and the recess are arranged such that a hinge is formed when the projection is received in the recess and the expansion portion is movable about an axis through the projection. The projection is insertable into the recess in a first angular orientation of an axis of the expansion portion relative to the axis of the body and is prevented from retracting out of the recess in a second angular orientation of the axis of the expansion portion relative to the axis of the body.
