The preferred embodiment of the present invention is generally described as a lordotic pre-sacral rod implant, or implant construct, for use in association with spinal fusion procedures. In an embodiment, the lordotic pre-sacral rod implant incorporates a washer configured to press against the endplate of the L5 vertebral body and thereby force the vertebral bodies of the lumbosacral junction into a lordotic orientation.

Lordotic rod-washer implant for lumbo-sacral fusion

Certain embodiments of the invention relate to a surgical procedure resulting in the fusion of transverse processes. The disclosure herein presents novel approaches for accessing transverse processes of the spine, novel methods for the delivery of fusion material for the fusion of said transverse processes, and novel tools to facilitate the procedure. Certain embodiments of the invention include a graft delivery assembly, which has a delivery shaft, delivery sheath, and at least one curved rod. Bony material is position with a graft delivery assembly, in which retraction of the delivery shaft or sheath places the bone fusion material to the fusion site. The graft delivery assembly further includes features to decorticate and prepare the bone surface for fusion.

Method and apparatus for minimally invasive posterolateral spinal fusion

Disclosed are surgical implants for providing therapy to a treatment site, tool sets and methods for minimally invasively accessing and deploying the implants within the spine. The treatment site may be a vertebral body, disc, and/or motion segments in the lumbar and sacral regions of the spine.

Spinal implants and implantation system

Disclosed are surgical implants for providing therapy to a treatment site, tool sets and methods for percutaneously accessing and deploying the implants within the spines. The treatment site may be a vertebral body, disc, and/or motion segments in the lumbar and sacral regions of the spine.

Minimally invasive surgical techniques including techniques and implants for provision of therapy to a spine from a lateral approach. Implants that may be used with other approaches to the spine are disclosed. Minimally invasive surgical techniques using one or more extended retractors to create an extended access route such as the non-limiting example of lateral access to the spine. Minimally invasive surgical techniques using internal retractors that may be reversibly expanded with a removable retractor inserter to create an extended access route. A linkage jack to expand a set of two or more extended retractors to create an extended access route.

Implants for spinal therapy

Spinal therapy lateral approach access instruments

Assemblies for implantation across one or more spinal motion segments to allow for control of the distance between bone anchors. Control of distance between bone anchors may be provided by one inter-anchor element pushing the pair of bone anchors apart and a second inter-anchor element pulling the pair of bone anchors together. Control of distance between bone anchors may be provided through use of dissimilar thread pitch. Compression of intervertebral disc space through controlled movement of a pair of anchored bone anchors towards one another.
