1. An implantable spinal fixation device, comprising:
- an elongate member having a first end and a second end with a center-line extending therebetween;
a plurality of bone screw receiving thru-holes formed in the elongate member, the thru-holes positioned proximate the center-line of the elongate member; and
a position-adjustable coupling element engaged to a portion of the elongate member, the coupling element positioned proximate the center-line and configured to releasably engage a spinal fixation element.

Abstract
Various embodiments of an implantable spinal fixation device are provided herein. In general, the device can include an elongate member having a first end and a second end having a center-line extending therebetween. Further, the elongate member can include any number of bone screw receiving thru-hole(s) positioned proximate (e.g., along or offset from) the center of the elongate member. Further, the device can include a position-adjustable coupling element proximate the thru-hole(s), and configured to releasably engage a spinal fixation element. Additionally, methods of occipital coupling of a spinal fixation element are provided herein.

20. A method of occipital coupling of a spinal fixation element, comprising:
-
fixing an inferior portion of a spinal fixation element to one or more vertebra; providing an occipital plate having a superior end and an inferior end and a plurality of bone screw receiving thru-holes positioned proximate a center-line of the occipital plate, the occipical plate further including a position-adjustable coupling element positioned proximate the center-line of the occipital plate; fixing the occipital plate adjacent the foramen magnum and offset from a midline defined by the spinal column; and fixing a superior portion of the spinal fixation element to the position-adjustable coupling element. - View Dependent Claims (21, 22, 23)

24. A method of occipital coupling of a spinal fixation element, comprising:
-
providing first and second spinal fixation elements; fixing an inferior portion of the first and second spinal fixation elements to one or more vertebra, the first and second spinal fixation elements positioned on opposites sides of a midline defined by a patient'"'"'s spinal column; providing a first and a second occipital plate, each occipital plate having a first end, a second end and a center-line extending therebetween, each plate further having a plurality of thru-holes proximate respective center-lines, and each plate also having a single rotatable and translatable coupling element positioned within an elongated thru-hole; fixing the first occipital plate adjacent the foramen magnum and offset in a first lateral direction from the midline defined by the spinal column; fixing the second occipital plate adjacent the foramen magnum and offset in a second lateral direction from the midline defined by the spinal column, the first and second occipital plates positioned on opposite sides of the midline defined by the spinal column; manipulating the coupling elements relative to the first and second occipital plates so as to align the first coupling with the superior portion of the first spinal fixation element and the second coupling with the superior portion of the second spinal fixation element; and fixing the superior portion of the first fixation element to the first rotatable coupling and fixing the superior portion of the second spinal fixation element to the second rotatable coupling. - View Dependent Claims (25)
