Abstract: A bone fastener includes a strand which may be threaded through drilled passages in separate but adjacent bone sections such that the ends of the fastener may be quick connected to one another. For example, one end of the fastener may be threaded through an aperture in the other end such that a self-locking and adjustably tensionable connection is achieved. In addition, a burr hole plate may be secured over a burr hole by threading the fastener through a connector on the burr hole plate and securing the fastener to the bone sections.
