Abstract: A prosthetic spinous process cross-link implant for the replacement of a posterior vertebral element. The implant includes a cross link body member with a pair of adjustable link arms connected to the cross link body to size the implant to specific anatomical configurations. The implant includes a rod clamp that is spring loaded to a forward position such that capturing a spinal rod on to the adjustable link arms to achieve a snap on effect thereby increasing the ease of installation. A plurality of spinous process cross-link implants can be assembled as a kit wherein the set includes a group of spinous process type yokes and bridge type yokes each group including both fixed and variable sized implants.

Abstract: The present invention relates to a prosthetic spinous process cross-link for the replacement of a posterior vertebral element. The vertebral element may include a natural lamina extending from a pair of natural pedicles and a natural spinous process extending from the lamina. The prosthetic spinous process cross-link may include a first pair and a second pair of screws attached to a vertebral body and a first rod and a second rod, the first rod extending between the first pair of screws and the second rod extending between the second pair of screws. A prosthetic lamina attached to the rods is also provided, along with a prosthetic spinous process extending from the prosthetic lamina.
