Abstract
A pivotal bone anchor assembly includes a receiver having a first channel for receiving a rod and a central bore with a seating surface adjacent a bottom opening with a first cut-out portion. The assembly also includes a bone anchor having an upper end portion pivotably engageable with the seating surface, an anchor portion opposite the upper end portion, and a neck extending between the upper end and anchor portions. The assembly further includes an insert positionable in the central bore with a second channel alignable with the first channel, a concave lower surface engageable with the upper end portion of the bone anchor, and a second cut-out portion alignable with the first cut-out portion. The neck and at least a portion of the upper end portion of the bone anchor are positionable into the first cut-out portion and the second cut-out portion, respectively, to provide for increased pivotal angulation of the bone anchor with respect to the receiver in the direction of the cut-out portions.
