1. A total artificial spinous process (spino)-laminar prosthesis (TASP-LP) comprising:
- a hinge pin having a first end, a second end, and a pin body between the first end and the second end;
a body comprising;
a first winged spinous process-laminar hinged portion on a first side of the body, wherein the first winged spinous process-laminar hinged portion has a first wing extension and a first hinge connection, wherein the first winged spinous process-laminar hinged portion defines a first plurality of holes through the first winged spinous process-laminar hinged portion including at least one first screw hole defined through the first wing extension at an angle configured to allow a first screw to pass through and into natural lamina and at least one first hinge hole extending through the first hinge connection that is sized and configured to receive the hinge pin; and
a second winged spinous process-laminar hinged portion on a second side of the body, wherein the second winged spinous process-laminar hinged portion has a second wing extension and a second hinge connection, wherein the second winged spinous process-laminar hinged portion defines a second plurality of holes through the second winged spinous process-laminar hinged portion including at least one second screw hole defined through the second wing extension at an angle configured to allow a second screw to pass through and into natural lamina and at least one second hinge hole extending through the second hinge connection that is sized and configured to receive the hinge pin, wherein the first winged spinous process-laminar hinged portion and the second winged spinous process-laminar hinged portion are disposed on opposite sides of the hinge pin with the hinge pin extending through at least part of the first and second pin holes of the first and second hinge connections so as to allow the first winged spinous process-laminar hinged portion to pivot with respect to the second winged spinous process-laminar hinged portion to vary a distance between the first and second wing extensions.
