Methods and devices are provided for spinal fixation. In one exemplary embodiment, the methods and devices provide a spinal fixation system that can include a spinal connector which can be disposed within a recess in a head of a bone anchor. The spinal connector can have a variety of configurations. The methods and devices are particularly useful for unilateral fixation, in which one or more levels of the spine are stabilized along a single lateral side of the spine.

Methods and devices are provided for spinal fixation. In one exemplary embodiment, the methods and devices provide one or more points of fixation located adjacent to a first fixation point at which a bone anchor is implanted in bone. For example, an extension member can be coupled, either directly or indirectly, to a bone anchor, and a fastener can be used to anchor the extension member to bone at a second point of fixation adjacent to the first point of fixation. The second point of fixation can be effective to prevent rotation or other movement of the bone anchor, thereby stabilizing the bone anchor. The methods and devices are particularly useful for unilateral fixation, in which one or more levels of the spine are stabilized along a single lateral side of the spine.

A flexible spinal fixation element is provided that is movable between a first position, in which the spinal fixation element is adapted to be angularly manipulated, and a second, locked position, in which the spinal fixation element is aligned in a desired orientation and is immovable. The configuration of the flexible spinal fixation element can vary, but the fixation element is preferably formed from a bioimplantable member having segments or a bellows configuration that allows the fixation element to be selectively configurable between the first and second positions. In use, the flexibility of the spinal fixation element allows the fixation element to be introduced through a percutaneous access device, thereby advantageously allowing the fixation element to be implanted using minimally invasive techniques.

Disclosed herein are methods and devices for distracting adjacent vertebrae during surgical procedures for implanting spinal prostheses. In an exemplary embodiment, a distractor is disclosed that maintains the empty space between adjacent vertebrae following a discectomy, and that can removably mate with other surgical instruments, such as, for example, a filler bar, an implanting tool, or a funnel. In other embodiments of the present invention a distractor is disclosed having various features to assist in implanting a spinal prosthesis, such as, for example, an angled distal end and/or an expandable paddle. In another embodiment of the present invention, an articulating inserter is disclosed. Moreover, various implants and funnels are also disclosed herein.

A spinal implant including a stabilization member coupled to an elongate member is herein provided. The implant can be configured for placement within a facet joint in an intra-facet or trans-facet configuration. Also, the implant can include a fusion-promoting bioactive material thereby providing a single device capable of spinal stabilization and/or fusion. Furthermore, a method of placing such an implant within a facet joint in an intra-facet or trans-facet orientation is hereby provided.

Embodiments of the present invention provide an implant having a protrusion. The protrusion aids in the insertion and placement of the implant as well as the spinal fixation element. In certain embodiments the protrusion may be configured as a guide for the insertion of the spinal fixation element as well as closure mechanisms for connecting the spinal fixation element to the implant.
