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 54):
A spinal fixation assembly comprising:\n a closure top having a 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; a receiver having opposed upright arms each with a lower inner surface and an extension portion, each extension portion having an upper inner surface extending above the lower inner surface, the upright arms and extension portions defining a rod-receiving channel therebetween, the receiver upright arm and extension portion inner surfaces each having a receiver flange extending discontinuously and helically along the inner surfaces, the receiver flange having a receiver load flank surface and a receiver splay control ramp; the closure top being rotationally receivable and advanceable in a downwardly direction into the channel via engagement between the closure top flange and the receiver flange, the receiver upright arms and extension portions configured to splay outwardly with respect to each other during rotational advancement of the closure top therebetween; the closure top flange and the receiver flange allowing an outward splay of the upright arms and extension portions as torque between the closure top, the extension portions and the upright arms increases during loading of the closure top load flank surface and the receiver load flank surface while moving a portion of a rod positioned within the channel above a channel bottom surface downward along a portion of the channel by the 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 extension portions and upright arms when the portion of the rod is moved along the channel toward the channel bottom surface by the rotational advancement of the closure top.
