Abstract
A spinal joint for use in spinal surgery includes two blocks pivotally connected to each other. One block is secured to a vertebrae with a bone screw, which the other block connects to another spinal joint. The blocks rotate relative to one another, and can be locked relative to one another in various angular positions. Serrations on one block engage with corresponding serrations in the pivotal connection portion of the second block at a selected angle, and are locked in place by a locking screw.
