Abstract
An adjustable spinal fixation system is composed of a collection of anchoring assemblies attached, via a variety of connectors, to spine-stabilizing rods. The anchoring assemblies include a linking member attached in a ball-and-socket fashion to a bone-engaging member that is adapted to engage a spinal bone of a patient. The linking member joins one of the included connectors to an associated bone-engaging member. The connectors are selectively attached to one of the stabilizing rods. The anchoring assemblies each include a support collar and a split retention ring that cooperate to allow adjustment of the bone-engaging member and corresponding connector during surgery. When surgery is complete, a securing nut and locking bolt cooperate with the support collar and split retention ring to maintain the relative position of the entire fixation system, preventing unwanted movement between the system components.
