A novel integrated posterior lumbar interbody spacer screw construct which will allow for posterior lumbar interbody fusion to be performed with a stable construct to achieve arthrodesis, but without the requirement of pedicle screws to stabilize the spine. In this concept, screws which engage the interbody spacers and form an integrated spacer screw construct are placed from a posterior approach. The screws engage the vertebral body, provide stability to allow for development of a solid arthrodesis, and also provide for compression across the disc space to enhance the likelihood of a successful arthrodesis and secure the interbody spacer to prevent posterior migration. |
