SPINOUS PROCESS BASED LAMINOPLASTY

摘要

In one embodiment of the invention, a cervical implant may include a spinous process base coupled to a lateral mass base. During open door laminoplasty, a surgeon may connect lateral mass base to right lateral mass and connect spinous process base to spinous process to fixedly retract left lamina from left lateral mass. Thus, 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.
