The posterolateral approach is an extension of the standard posterior (laminectomy) approach and thus dissection can easily be mastered as compared to the lateral and anterolateral approaches. This approach provides a wide exposure of the cervical lateral masses, pedicles and transverse processes.
Devices and techniques for a posterior lateral disc space approach
This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach.

Artificial Disc Replacement Using Posterior Approach
Methods and devices are provided for replacing a spinal disc. In an exemplary embodiment, artificial disc replacements and methods are provided wherein at least a portion of a disc replacement can be implanted using a posterolateral approach. With a posterolateral approach, the spine is accessed more from the side of the spinal canal through an incision formed in the patient's back. A pathway is created from the incision to the disc space between adjacent vertebrae. Portions of the posterolateral annulus, and posterior lip of the vertebral body may be removed to access the disc space, leaving the remaining annulus and the anterior and posterior longitudinal ligaments in tact. The disc implant can be at least partially introduced using a posterolateral approach, yet it has a size that is sufficient to restore height to the adjacent vertebrae, and that is sufficient to maximize contact with the endplates of the adjacent vertebrae.

Minimally-invasive retroperitoneal lateral approach for spinal surgery
InactiveUS20120035730A1Realize distributionMinimize traumaSurgerySpinal implantsSpinal columnIntervertebral spaces
A method is disclosed for introducing a spinal disc implant into an intervertebral space of a subject. The subject is placed in a lateral position, and the anterior face of the spinal disc intervertebral space is accessed, between the L5 and S1 vertebrae, from an anterior and lateral retroperitoneal approach. An operative corridor to the anterior face of the spinal disc space is established by introducing a retractor instrument anterolaterally to the spinal disc space between the anterior superior iliac spine and the anterior inferior iliac spine. The damaged spinal disc contents are removed from the intervertebral space through the operative corridor, and the implant is advanced into the intervertebral space at an oblique angle and pivoted to position the implant substantially laterally within the intervertebral space. Elongated retractor and insertion instruments, as well as a modified disc implant, are also disclosed for carrying out the method.

Artificial disc replacements (ADRS) are configured for implantation using a lateral, anterior-lateral, or posterior-lateral approach. A first component having a first segment resides in the disc space for articulation purposes, with a second segment adapted for fixation to the lateral outer surface of one of the vertebral bodies. A second component having a first segment resides in the disc space for articulation purposes, with a second segment adapted for fixation to the lateral outer surface of the other vertebral body. The first segments of the two components may articulate against one another without a spacer, or a spacer forming a mobile bearing may be disposed between the first segments of the two components. In the preferred embodiment, one or both of the two components are in the form of bent plates such that the second segment is positioned against a lateral wall for fixation. In the preferred embodiment, screws are used through the second segment and into a vertebral body. The screws are located in different vertical locations, and may diverge or converge vertically or horizontally to resist pull-out.

Transosseous spine core approach method implant and instrumentation
InactiveUS7637927B2Simple procedureShorten the timeInternal osteosythesisJoint implantsSpinal columnSurgical approach
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.
