摘要 An assembly that includes a fixator component, a clamping mechanism, a screw head, a load sharing mechanism, and a blocker. The fixator component further includes a bulbous end, a neck portion, and a threaded end. The clamping mechanism is positioned around the neck portion of the fixator component. The load sharing mechanism is positioned in between the screw head and the bone fixator component. The screw head further includes a pair of diametrically opposed arms, a socket and a slot.
