Abstract
In one embodiment of the invention, a cervical implant may include a spinous process base coupled to a lateral mass base. During an open door laminoplasty, a surgeon may connect the lateral mass base to the right lateral mass and connect the spinous process base to the spinous process to fixedly retract the left lamina from the left lateral mass. As a result, no implant is needed to bridge or span the open door. Instead, the implant may span the hinged lamina. Consequently, no holes must be drilled in left lamina (open door side). If no holes must be drilled in left lamina, the surgeon lessens the risk of drilling a drill bit through left lamina and into spinal cord. Furthermore, no implant base or portion, screw, bolt, or fastener of any form needs to be affixed to inferior side of the left lamina, thereby avoiding irritation of the spinal cord by the implant.
