Abstract
A bone anchor system for securing a rod to a head of a shank includes a receiver with upright arms defining an open channel. Each upright arm includes a planar top surface between an upper outer surface and an arcuate top inner edge, a horizontally-extending tool engagement groove below the upper outer surface, and an inner concave surface extending downward from the arcuate top inner edge. The tool engagement groove includes a downwardly-facing upper groove surface, an outwardly-facing inner groove surface, and an opposed upwardly-facing lower groove surface extending outwardly to an outer arm surface having a width greater than the width of the upper outer surface. The bone anchor system also includes tooling with a receiver attachment portion having a downwardly-opening recess with an inner convex surface that is closely receivable with the inner concave surface, and an inwardly-directed protrusion that is closely receivable within the horizontally-extending tool engagement groove.
