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 wing with a distal portion that can define a plurality of auxiliary bone anchor openings. Each auxiliary bone anchor opening can receive an auxiliary bone anchor that can augment fixation of a primary bone anchor of the bone anchor assembly. The plurality of auxiliary bone anchor openings can be oriented such that, when the wing is coupled to a primary bone anchor assembly of a vertebral level in a first configuration, at least one auxiliary bone anchor can be driven to extend across a facet plane of the vertebral level and, when coupled in a second configuration, each auxiliary bone anchor received within the wing can be driven to conform to the vertebral level.
