LAMINOPLASTY ROD SYSTEM

摘要

A laminoplasty rod system that allows for variable angulation, translation and rotation of a spinal lamina bone portion associated with a laminoplasty. The laminoplasty rod is configured for use with a polyaxial spinal rod bone screw assembly that is adapted to be anchored to the vertebra associated with the laminoplasty, and is attachable to the spinal lamina bone portion. The laminoplasty rod system is characterized by 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, 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.
