Spinal motion preservation assemblies adapted for use in a spinal motion segment are disclosed including the process for delivering and assembling the spinal motion preservation assemblies in the spinal motion segment via an axial channel created with a trans-sacral approach. The spinal motion preservation assemblies make use of a dual pivot. A number of different embodiments of spinal motion preservation assemblies are disclosed which include at least one component adapted for elastic deformation under compressive loads. The disclosed mobility preservation assemblies provide for dynamic stabilization (DS) of the spinal motion segment.

Cutter blades made of shape memory materials. Rotation of a cutter blade as part of a cutter assembly within an intervertebral disc space cuts the material present there for removal from the intervertebral disc space. Cutter blades with different attributes (such as throw length, cutter blade angle, type and location of blade edges) are adapted to achieve different objectives within the intervertebral disc space. The use of a hollow ground to enhance the cutting action of a blade edge is described in connection with the creation of cutter blades. A variety of thin cutter blades are described which may be used in the interior of a thin intervertebral disc (having a reduced distance between the endplates of the adjacent vertebral bodies).

An alignment jig that creates a plurality of parallelograms may be used to align an external alignment line with an internal target path. The internal target path is within the patient's body and may be defined by two guide pin tips. The alignment jig may be created so that it creates the external alignment line to be co-linear with the internal target path or the external alignment line may be parallel to the internal target path by offset a distance from being co-linear. The external alignment line may be used in the provision of therapy such as the delivery of a screw to a precise location in the provision of therapy to a portion of the spine.

Disclosed are surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the S1 vertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and/or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures.

Disclosed are methods and apparatus for the provision of spinal therapy to two or more adjacent motion segments accessed through a trans-sacral approach. The spinal therapies include fusion and dynamic stabilization with and without a distraction of the most cephalad motion segment of the two or more adjacent motion segments provided therapy. The disclosure includes methods and apparatus to impart a distraction on a second more caudal motion segment after providing therapy to the more cephalad motion segment. Related concepts for the extraction of previously inserted devices and the delivery and removal of plugs for plugging the interior cavities of implantable devices are disclosed.

Spinal motion preservation assemblies adapted for use in a spinal motion segment are disclosed including the process for delivering and assembling the spinal motion preservation assemblies in the spinal motion segment via an axial channel created with a trans-sacral approach. Many of the spinal motion preservation assemblies make use of a dual pivot. A number of different embodiments of spinal motion preservation assemblies are disclosed which include at least one component adapted for elastic deformation under compressive loads. The disclosed mobility preservation assemblies provide for dynamic stabilization of the spinal motion segment. Other variations and implementations of the teachings are disclosed, including the sheathed delivery of membranes in order to protect the membranes before and during deployment.

A driver for delivering an insert to a bone anchor, the bone anchor having an internal cavity with a set of internal threads, the driver adapted to rotate with respect to a bone anchor that is anchored in a vertebral body in order to engage external threads on the insert with the set of internal threads in the bone anchor and axially advance the threadedly engaged insert within the bone anchor while simultaneously preventing the bone anchor from rotating with respect to the vertebral body the driver having: 1) a threaded retention rod for engaging a bore in the insert; 2) a driver head to engage with the insert to apply torque to the insert and rotate the insert; and 3) an anchor stabilizer to engage with a proximal face of the bone anchor to prevent the bone anchor from rotating with respect to the vertebral body.
