A laminoplasty rod and rod system that allows for variable angulation, translation (distraction and/or compression) and rotation of a spinal lamina bone portion associated with a laminoplasty. The laminoplasty rod is used with a polyaxial spinal rod bone screw assembly anchored to the vertebra associated with the laminoplasty, and is attachable to the spinal lamina bone portion. The laminoplasty rod system provides positional attachment of the rod to the spinal components and fixation thereof in various orientations. The laminoplasty rod system includes a configured laminoplasty rod that fits into or onto the head of a polyaxial spinal rod bone screw assembly. A bone screw boss, defining a bone screw attachment configuration, is formed at one end of the laminoplasty rod. Preferably, but not necessarily, the bone screw boss is situated at an angled end of the rod having a pre-defined bend that provides for greater variation in rod orientation.
