Abstract:
Open implant closure structures include a helically wound guide and advancement flange form having splay control surfaces. Multi-start closures and closures with inner set screws have splay control contours for interlocking with cooperating flange forms of bone anchor receivers. Flange form heights, thicknesses and other geometry, such as splay control ramp angle may be varied.

Claim (Index 21):
A spinal fixation assembly comprising:\n a receiver having a set of arms, each of the set of arms having a lower inner surface and an extension portion, each extension portion having an upper inner surface extending above the lower inner surface; a channel defined by the set of arms and the extension portions; a closure top rotationally receivable and advanceable downwardly into the channel; a closure top flange extending continuously and helically about the closure top, the closure top flange having a closure top load flank surface and a closure top splay control ramp; and a receiver flange extending discontinuously and helically along the lower and upper inner surfaces of each of the receiver arms and extension portions, respectively, the receiver flange having a receiver load flank surface and a receiver splay control ramp, the closure top flange and the receiver flange allowing an outward splay of the receiver arms and the extension portions, as a torque between the closure top and the receiver set of arms increases during loading of the closure top load flank and the receiver load flank surfaces while moving a portion of a rod positioned within the channel downward along a portion of the channel by rotational advancement of the closure top in the channel, the receiver splay control ramp mutually engaging the closure top splay control ramp in an interlocking arrangement so as to constrain the outward splay of the receiver set of arms when the portion of the rod is moved along the channel toward a bottom of the channel by the rotational advancement of the closure top.
