ABSTRACT:
A retaining mechanism engages a bone fastener to a bone plate as the bone fastener is positioned through a retaining mechanism in a plate hole while preserving multi-axial capabilities of the fastener relative to the plate during insertion of the fastener. When the head of the fastener is positioned adjacent the plate, the head can optionally be received in the retaining mechanism and expand the retaining mechanism to fixedly engage the retaining mechanism into locking engagement with the plate and lock the bone fastener in position relative to the plate. In another form, the multi-axial capabilities of the bone screw is preserved or at least partially preserved when the bone fastener is finally positioned in the retaining mechanism.
