The device is comprised of a screw assembly including a base and a support configured for receiving one or more anchor assemblies. The support includes a top portion, a bottom portion and an interconnection means for coupling the base to the support. The interconnection means allows the support to be positionable in a first position that is substantially parallel to a long axis of the base and secondarily positionable substantially perpendicular to the long axis of the base. The base and the one or more anchor assemblies are configured for attachment to a structure in a patient.
