A method for inserting an interspinous spinal implant into an opened gap between first and second spinous processes of adjacent superior and inferior vertebras, respectively includes the following. First forming an opened gap between a first spinous processes of a superior vertebra and a second spinous processes of an adjacent inferior vertebra by first inserting a decompression knife into diseased areas of the adjacent superior and inferior vertebras, then cutting fascia tissue, then separating soft tissue from bone by rocking the decompression knife back and forth, and then inserting a broach cutter into the diseased areas of the adjacent superior and inferior vertebras and cutting interspinous ligament between the adjacent superior and inferior vertebras. Next, determining and selecting an appropriate sized and shaped interspinous spinal implant for the opened gap by inserting a sizing tool into the opened gap, and sizing the opened gap with the sizing tool. Next, inserting the selected interspinous spinal implant into the opened gap with an insertion tool, and then compressing first and second elongated components of the interspinous spinal implant onto first and second opposite sides of the first and second spinous processes with a compressor tool, respectively. Finally, locking the interspinous spinal implant onto the first and second spinous processes of the adjacent superior and inferior vertebras with a locking driver.

Methods and systems are disclosed for accessing and treating the interior of the facet joint for vertebral distraction and immobilization. The systems include a number of tools that facilitate access to the facet joint, distraction of the articulating decortication of the articulating surfaces, and delivery of implants and agents into the facet joint for fusion.

Apparatus and methods for spinal the treatment of abnormal spinal stability and stenosis of the spinal canal. In one embodiment, the apparatus and methods provide treatment via decompression and/or fixation of the spinal canal. One or more implants are used to fixate the posterior column of a spinal segment compromised of the superior and inferior immediately adjacent vertebral bones. In one variant, these disclosed devices are used to fixate the posterior column of a spinal segment while another orthopedic implant is placed into the anterior column of the same spinal segment, thereby providing circumferential decompression.

A cage holder includes an elongated body having a proximal end and a distal end, the elongated body extending from the proximal end to the distal end. The cage holder further includes means for transferring energy centrally from the proximal end to the distal end through the elongated body.

A stand-alone expandable interbody spinal fusion device, including a superior component, an inferior component, and an expansion mechanism operatively arranged to displace the superior component relative to the inferior component, the expansion mechanism including a threaded rod including a first end engaged with the superior component and a second end engaged with the inferior component, wherein when the threaded rod is rotated in a first circumferential direction, the superior component is displaced in a first direction relative to the inferior component.

Technologies are generally provided for devices, systems, and methods to provide spinal fixation, spinal stabilization, and/or spinal fusion. Example devices may include a first end and a second end with a middle portion extending between the first and second end. The first end may be configured to be in contact with a portion of a first or upper vertebra and the second end may be configured to be in contact with a portion of a second or lower vertebra in an adjacent vertebral pair. Portions of the vertebra which may be in contact with the device may include lamia, processes, vertebral bodies, and facet joints. The example devices may include bone engagement features, such as screws or similar fasteners, to enhance stabilization and fixation when in contact with the vertebrae. Additionally, the devices may include a bone integration feature to promote bone growth and to facilitate fusion between the vertebrae.

The present invention relates generally to medical devices, systems, and methods for use in surgery. In particular, the disclosed system and methods relate to an intervertebral spinal implant sized and dimensioned for the lumbar spine implantable via a posterior approach. The system includes an implant, instruments for delivering the implant.

Provided herein is an interspinous stabilization device, including: a central connection portion, a first side wing, a second side wing, a third side wing, and a fourth side wing. The first side wing extends from the central connection portion in a first direction. The second side wing extends from the central connection portion in the first direction. The third side wing extends from the central connection portion in a second direction opposite to the first direction. The fourth side wing extends from the central connection portion in the second direction. The central connection portion has at least one thread hole. The thread hole extends in a third direction substantially perpendicular to the first direction. The first side wing, the second side wing, the third side wing, and the fourth side wing each have a through hole.

The shim-type implant for distraction and fusion of cervical facet joints is provided. The implant has a generally box-like shape with a blunt leading edge that may be centered or offset to the inferior face. The implant may include a graft window for enhanced osseous through-growth after implantation. The implant is coated with hydroxyapatite (HA) and/or tri-calcium phosphate (TCP) to allow for osteo-conduction, is porous, and has a roughened surface with serrations on the superior and inferior faces. The implant may be fabricated from a titanium or tantalum alloy. In an embodiment, a set of tools is provided with a chisel and one or tongs and one or more decorticators for inserting the implant.

A fusion device assembly for fusion of a joint, including a first screw portion, including a first distal end, a first proximal end, a first radially outward facing surface, and a first hole, a second screw portion, including a second distal end, a second proximal end, and a second radially outward facing surface, and a section, including a first end slidably engaged with the first hole, a second end non-rotatably secured to the second distal end, and a third radially outward facing surface.
