A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and / or insert an intervertebral implant.

A prosthetic implant, and more particularly, with a prosthetic implant having biplanar angulation and that can be inserted into a disk area generally straight using a posterolateral approach.

Implants, tools and techniques facilitate a percutaneous posterior lateral approach to the placement of an in-situ cage, and an inventive cage design to meet this objective. In terms of apparatus, the invention includes a laterally expandable cage, including a locking gate, enabling the system to be introduced into an intradiscal space through a minimally invasive percutaneous posteo-lateral approach. In addition to the cage designs, adapted to hold bone graft and / or other biologic materials, the invention includes other novel instruments, including an introducer associated with cage placement, deployment and closure.

Instrumentation for fixing at least two spinal vertebrae by pedicle screw type bone anchoring implants and connecting elements via the posterior or posterolateral approach has at least one bone anchoring element designed to be fixed to a vertebra, pre-mounted with a disposable mounting tube and a sterile sealed packaging. A kit of instruments for inserting or removing a spinal implant, has at least two threaded bone anchoring elements, a rod-type or plate-type connecting element mechanically connecting the bone anchoring elements and locking elements for locking the connecting element in position in relation to the anchoring elements, in order to perform all of the surgical procedures relating to the insertion or removal of the implant, all of the required instruments are disposable and packed in a sterile manner in one or several sealed packagings.

Various exemplary instruments for introducing an implant using a posterolateral approach are also provided, as well as various exemplary methods for using such instruments. In general, the instruments are configured to interconnect to an implant and / or to a guide member such that the components are all docked relative to one another. This allows the various components of a multi-piece implant to be mated intraoperatively within the disc space, and in particular to be guided into alignment with one another.

The disclosure relates to a device for establishing an anatomical reference point of an intervertebral disc for the attachment of at least one instrument Intended for the implantation, through a posterior or posterolateral approach, of a disc prosthesis or osteosynthesis cage as a replacement for the intervertebral disc. The device includes at least two means for bone anchorage each intended to be attached to a vertebra adjacent to the disc, a coupling element for the instrument and elements for adjusting the position of the coupling element relative to the position of the disc.

The transosseous spinal core approach (TOSCA) represents a novel approach to the interior of the spine or disc space by removing a core from a first bone and performing a procedure, and / or making further enlargements and cuts in the first bone and performing a procedure, and / or making another cut into an adjacent disc space from the first bone hole and performing a procedure and / or continuing by cutting into another second bone and performing a procedure. The process can be further extended into additional spine levels by extending the cutting process. A core can be made at more than one level. The preferred surgical approach is a posterior lateral approach. An anterior surgical approach can be used as well. Any practical surgical approach or any combination of surgical approaches can be utilized to gain access to the first bone. Once the surgical soft tissue access to the first bone is completed TOSCA can be used to gain access to the interior of a vertebral body or disc space. After the procedure is completed in a vertebral body or disc space, usually at least a portion of the bone core is replaced to fill in the core hole.
