Abstract: A method for performing percutaneous spinal interbody fusion on a spine of a patient can include inserting without direct visualization a neuro-monitoring dilating probe into the patient, performing neuro-monitoring via the neuro-monitoring dilating probe, advancing the neuro-monitoring dilating probe into a disc space, passing a second dilator over the neuro-monitoring dilating probe, and advancing the second dilator into the disc space. A kit for performing percutaneous spinal interbody fusion can include a neuro-monitoring dilating probe, a second dilator, a tissue removal tool, an access portal comprising an adjustable depth stop, and a discectomy verification device.

Abstract: A hybrid spinal implant for performing an intervertebral fusion procedure can include a pair of spacers separated by an expandable container that are formed of a porous titanium scaffold material. A connecting rod can span longitudinally between the pair of spacers. The spacers can be formed of titanium or PEEK, with endplates that are formed of the porous titanium scaffold material. The endplates can be bioactive. Exposed surfaces of the porous titanium scaffold material can be coated in a snag-preventing substance. The expandable container can be formed of a mesh material.

Abstract: A method of performing percutaneous interbody spinal fusion on adjacent vertebrae in a patient including the steps of: creating a percutaneous access opening on the patient, using indirect visualization to establish a surgical path through the access opening, creating a cavity in a disc space between the adjacent vertebra, without retraction, inserting an expandable implant into the cavity, the implant configured to fit through the access opening into the cavity, and expanding the implant within the cavity.

Abstract: A method of placing an implant for intervertebral fusion between adjacent vertebral bodies in a patient includes inserting the implant in a space between the adjacent vertebral bodies such that both a first intervertebral spacer body and a second intervertebral spacer body contact each of the adjacent vertebral bodies. The first intervertebral spacer body is spaced apart from the second intervertebral spacer body. An expandable container portion of the implant disposed between the first intervertebral spacer body and the second intervertebral spacer body is filled with fill material such that the expandable container expands to contact each of the adjacent vertebral bodies.

Abstract: Disclosed are instruments, implants and methods of accessing the spine from an Anterior to the Psoas (ATP) approach, performing a discectomy through an ATP approach and then placing an intervertebral implant via an ATP approach for spinal fusion.

Abstract: A method for performing an efficient and thorough percutaneous discectomy includes making into the patient a percutaneous incision, which is a small stab wound, no more than approximately 10 mm in length. A stimulated combination neuro-monitoring dilating probe is passed through an approximately 10 mm or less skin incision and into a patient's disc space to establish a safe path and trajectory through Kambin's Triangle. Once a neuro-monitoring dilating probe is in the disc space, a second dilator is placed over the neuro-monitoring dilating probe and impacted into the disc space. Neuro-monitoring dilating probe may then be removed. An access portal optionally combined with a force dissipation device may then be placed over the second dilator and into the disc space. The second dilator is removed and then discectomy instruments may be placed through the access portal to perform the discectomy.

Abstract: Provided is a variable lordotic expanding implant with a centralized graft deployment delivery channel (tube) with (or without) an expanding footprint mesh component which is deployed by graft material injection.

Abstract: A portal system for intervertebral surgical fusion procedures includes a longitudinally elongated hollow tubular body comprising a first wall, a second wall opposing the first and a third wall spanning from a first edge of the first wall to a first edge of the second wall. A channel is defined longitudinally through at least one of the first, second and third end walls. The fourth wall of the body is at least partially open or can be completely enclosed.

Abstract: An implant insertion instrument provides a guide through tissue (skin, fascia, musculature) and into a vertebral space after a discectomy. The instrument slides onto a guide wire and defines a path for the implant to be delivered to the vertebral space. The guide expands laterally as required to accommodate the implant as the implant slides through a channel defined in the guide, which allows distraction of the vertebral bodies while maintaining a small incision in the patient.

Abstract: An inserter includes a knob at its proximal end. The knob actuates linear motion of a slide at the distal end of the inserter. The linear motion of the slide separates two pins that project from a distal end of the inserter. The pins engage and release corresponding holes defined in the faceplate of an implant. The pins can project at an oblique angle from the longitudinal axis of the inserter. The angle of projection of each pin can be different so that a jaw-like action is provided, which securely grasps the implant via the holes in the faceplate.

Abstract: An expandable interbody device for use in the spine is configured to fit through Kambin's Triangle. The expandable interbody device can include a body defining a front end, a rear end and a plurality of sidewalls spanning between the front and rear ends, an expandable member pivotally attached to the body such that the expandable member pivots outwardly from one of the plurality of sidewalls and a screw threaded into the body through the rear end thereof. The expandable member defines an actuator flange that projects into the body. The screw abuts the actuator flange such that contracting the screw into the body causes the expandable member to pivot outwardly from the body.

Abstract: A method of performing percutaneous interbody spinal fusion on adjacent vertebrae in a patient including the steps of: creating a percutaneous access opening on the patient, using indirect visualization to establish a surgical path through the access opening, creating a cavity in a disc space between the adjacent vertebra, without retraction, inserting an expandable implant into the cavity, the implant configured to fit through the access opening into the cavity, and expanding the implant within the cavity.

Abstract: A midline retractor provides access for the placement of PARS screws and other surgical sites. A lower profile allows for better visualization of the patients anatomy and provides better access for surgical instruments. The retractor may include integrated lighting, such as fiber optic lighting or other suitable lighting. The blades of the retractor may include a textured profile, such as diamond plating, grooves, etching or any other desired textured treatment on the blades. The texture on the blades may keep tissue from migrating down the blades and may prevent the blades from slipping up and out of the patient. The PARS retractor may include a blade rotation locking mechanism and/or a blade toe feature that allows for ease of use and an adjustable blade toe. The retractor may also include a rack release that provides for free movement of the rack.

Abstract: The invention provides a method of correcting numerous bone abnormalities including bone tumors and cysts, avascular necrosis of the femoral head, tibial plateau fractures and compression fractures of the spine. The abnormality may be corrected by first accessing and boring into the damaged tissue or bone and reaming out the damaged and/or diseased area using any of the presently accepted procedures or the damaged area may be prepared by expanding a bag within the damaged bone to compact cancellous bone. After removal and/or compaction of the damaged tissue the bone is stabilized.
