Abstract
Assemblies, systems and components for a hybrid jointed bone screw system. A receiver member having an upper opening and a lower opening also includes an internal mating bone anchor interface channel at the bottom. A bone anchor is loaded into the lower internal mating bone anchor interface opening of the receiver member, and an anchor pin is 'pushed' through the receiver member and through the bone anchor head to retain the bone anchor member. The bone anchor is capable of single-axial positioning throughout a range of motion of about 180 degrees. An elongated member may be placed in the upper channel of the receiver member and a compression retaining member applied via the upper opening. The compression retaining member presses down on the elongated member, which presses down on a floor of the upper channel, locking the elongated member between the retaining member and the receiver member floor.
