Minimally-invasive retroperitoneal lateral approach for spinal surgery

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.

Method of lateral facet approach, decompression and fusion using screws and staples as well as arthroplasty

A method of performing vertebral facet fusion by lateral approach and related devices. The lateral approach to facet fusion involves identifying the lateral mass and introducing any of the fixation methods known or described herein laterally at one or more facets through the use of a Kirschner wire guide, a cannulated bone drill and cooperatively cannulated staple guide. A surgical bone staple have a perforated bridge is used across the lateral facet joint where fixation is required. Where fusion is desired, a bone screw have lateral perforations of the shank is inserted through the cannulated staple guide and bridge perforation at the joint to promote fusion. A staple cap and graft container for overlay grafting may be utilized for additional fusion. The method involves less surgical time, reduced blood loss and discomfort for the patient as compared to the posterior approach.

Transosseous spine core approach method implant and instrumentation

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.

A device and method for removing tissue, and if required, other undesired materials from an intervertebral disc or vertebral body. An elongated arcuate, and preferably S-shaped tool is used to progressively remove material from the interior of the mammalian intervertebral disc or vertebral body. A sheath introduces the elongated tool by a posterior, postero-lateral or lateral approach. The shape of the elongated tool is formed within a guide or lumen of the sheath for transportation through the sheath. The elongated tool assumes its predetermined arcuate shape when no pressure or force is applied to the tool by the sheath as the elongated tool exits the sheath. The device and method allow positioning of new material in the intervertebral disc and / or vertebral body. The new material may be tissue, therapeutic agents, mechanical devices such as spacers, or agents that will fuse vertebral bodies.
