Abstract:
1. A spinal fixation system, comprising: at least one rod; at least one screw having a head at a first end, wherein the screw has a longitudinal axis associated therewith; one body to which the rod and the screw are attached; a first compression element that cooperates with the body to attach the rod to the body; a second compression element that cooperates with the body to attach the screw to the body; wherein the body comprises a screw head receiving chamber which receives the screw along a longitudinal axis of the screw head receiving chamber and which contains the head of the screw; wherein the body comprises a rod receiving channel defined between two opposing sidewalls, the rod receiving channel extending radially along a radial axis and longitudinally along a longitudinal axis, the rod being seated in the rod receiving channel along the longitudinal axis of the rod receiving channel, and the first compression element being received along the radial axis of the rod receiving channel, wherein the radial axis and the opposing sidewalls are non-intersecting; wherein the screw head receiving chamber and the rod receiving channel are laterally offset from one another; wherein the rod receiving channel is angled relative to the screw head receiving chamber such that the radial axis of the rod receiving channel and the longitudinal axis of the screw head receiving chamber are oriented at an oblique angle; and wherein the second compression element comprises a compression screw which interfaces with internal threads associated with the screw head receiving chamber.
