A posterior spinal prosthesis is configured to cover exposed portions of a spinal column especially, but not necessarily, as a result of a medical spinal procedure and particularly, to provide posterior coverage of an exposed spinal cord, soft tissue, Foramen and / or adipose tissue, associated with one or more vertebrae as a result of the removal the spinous processes and / or the spinous process and laminar hoods from the one or more vertebrae of the spine as a result of a spinal decompression procedure or other reason. A plate forming the prosthesis is connectable to spine rod constructs implanted on lateral sides of the vertebrae and projects in the posterior direction relative to the connection. The plate is generally curved in the superior / inferior direction to provide either a lordotic or kyphotic curvature depending on the portion of the spine to which the prosthesis is utilized. As such, the posterior spinal prosthesis may be used on any portion of the spine such as the cervical vertebrae, the thoracic vertebrae and / or the lumbar vertebrae. The present posterior spinal prosthesis also provides posterior stabilization of the associated vertebrae as well as aiding in preventing post operative soft tissue cavitation at the decompression site.
