Abstract: Devices, systems and methods for surgical fixation, including multi-screw anchoring devices for anchoring to various anatomical locations such as a sacral level or other anatomy of the spine. Anchoring devices include screw assemblies that are adjustable in a variety of different ways to grant a surgeon various options for placement and/or orientation of the primary and supplemental fixation screws.

Abstract: A cross connector assembly is provided. In one embodiment, the cross connector is configured to engage a pair of rods in a spinal implant assembly. In an exemplary embodiment, the cross connector assembly includes at least one elongated top member having a pair of hooked-shaped ends and a pair of sliding members configured to slideably engage the at least one elongated top member. The cross connector may further include an upper fastener and a lower fastener engaged with the upper fastener configured to translate upon rotation of the upper fastener and engage the sliding members, biasing them from a first position to a second position.
