Various systems and methods for treating the spine are provided. A portal system can be provided for treating the spine. The portal system can include a portal comprising a proximal end and a distal end, a first passageway extending between the proximal end and the distal end, a second passageway extending between the proximal end and the distal end, and a latch. The bone tie can include a head, a body section comprising one or more gears, and a fastener section comprising a ratchet.

A method for fusing a spinal sacroiliac joint and a surgical kit. The kit includes a bone-void filler, stabilization device or implant, a guide pin, a joint locator, a set of dilation tubes, a reamer, a novel directional cannula, a novel tapping cap, a novel drill guide, a drill bit, and a novel implant positioner. The method includes the steps of locating the sacroiliac joint, retracting the soft tissue exposing the graft site, removing any bone obstructions and preparing a relatively smooth graft site horizontal to the immediate sacroiliac joint, creating a cavity in the ilium and sacrum to a predetermined depth that spans the sacroiliac joint, inserting a novel stabilization implant into the cavity, and seating the implant within the cavity at a predetermined depth.

The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

A surgical instrument includes a first member defining an axis and having a scraping surface configured to scrape tissue. A second member includes a cutting surface that is rotatable relative to the first member. The second member has a maximum length defined by opposite end surfaces of the second member. The end surfaces are each disposed within the first member. A third member includes an outer surface defining at least a portion of a passageway configured for disposal of the scraped tissue. The third member is fixed with the first member. The cutting surface is rotatable relative to the third member to transfer the scraped tissue along the axis. Systems and methods are disclosed.

A surgical instrument having a first member engageable with a first end of a fastener having a second end configured to penetrate tissue. A second member includes an expandable member configured for engaging the first end. Systems and methods are disclosed.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

In a surgical method, an elongate probe is inserted into a spinal disc exemplarily into a nucleus pulposus thereof in a direction generally parallel to vertebral end faces adjacent to the spinal disc. During the inserting of the elongate probe, the probe is ultrasonically vibrated. Thereafter, while ultrasonically vibrating the elongate probe, one moves the elongate probe to sever a prismatic portion of the spinal disc including a prismatic section of the nucleus pulposus. The prismatic portion of the spinal disc is removed from a remaining portion of the spinal disc.

A percutaneous spinal cross link system for interconnecting a spinal fusion construct on one side of the longitudinal axis of the spine with a spinal fusion construct on the other side of the longitudinal axis may include a cross bar connected at each end by a respective connector to a respective spinal fusion rod of each of the spinal fusion constructs. The connector may include a rod receiving portion adapted to receive one of the spinal fusion rods and a cross bar receiving portion adapted receive the cross bar in an orientation generally perpendicular to the spinal fusion rod. A cannula defined by two spaced apart blades may be connected to the connector for defining a minimally invasive pathway through body tissue for introduction of the cross bar to the connector. Other tools for use with the system are also disclosed.

A system for restricting flexion of a spinal segment in a patient comprises a constraint device having a tether structure and a compliance member coupled with the tether structure. The tether structure is adapted to be coupled with a superior spinous process and a sacrum. The system also includes an anchor member that is anchored to the sacrum. The anchor member has an attachment feature that is adapted to couple with the constraint device.

Tools adapted for spinal distraction are provided. More specifically, tools having an elongate shaft connected to a head portion are provided for imparting a force for displacing vertebral bodies. The tools may comprise features, such as textured surfaces or the ability to transmit pressure, for cleaning and preparing a spinal disc space for subsequent tools and procedures. A plurality or set of distraction tools is contemplated where the plurality of tools is made up of tools having various distinctions from one another. Such distinctions may be in the way of length, width, angle, and other geometric features or may comprise differences in materials or additional features.
