Patent ID: 8603142

Claim:
An implantable device for fixation of spinous processes, comprising: first and second spaced plates, each comprising a collar pivotally positioned within a socket, the first plate having a first surface facing a second surface of the second plate; and an interbody cage comprising a first post extending from a first face and a second post extending from an opposing second face, the first and second posts having a longitudinal length, wherein the first plate is configured to be selectively fixedly connected to the first post at a first connection point and the second plate is configured to be selectively fixedly connected to the second post at a second connection point and, wherein the first and second connection points can be positioned along the longitudinal length of the first and second posts such that a distance between the first surface and the second surface can be varied without changing the longitudinal length of the first and second posts, and wherein, when the first and second plates are connected to the first and second posts, the first and second plates can move polyaxially with respect to each other.
