Abstract
Bone anchor assemblies and related methods are disclosed herein that can provide for improved fixation of a primary bone anchor. A bone anchor assembly can include a base rotatably received within a rod-receiving member. The base can have a toroid body with a radially-extending portion including at least one auxiliary bone anchor opening that can receive an auxiliary bone anchor to augment fixation of a primary bone anchor of the bone anchor assembly. The base can be rotated relative to the rod-receiving member and the primary bone anchor such that the at least one auxiliary bone anchor opening can be placed in a desired position for supplemental fixation.
