摘要： A method and apparatus for providing an adjustable length surgical implant is provided, wherein the surgical implant is readily adjustable by a surgeon using a surgical tool sized for use with the surgical implant. Adjustment of the surgical implant further requires a small incision through the skin prior to the adjustment of the length of the implant, such that the potential for infection is greatly reduces and the associated trauma of surgery is lessened for the patient.

摘要： An intervertebral implant having an endplate that can be slidably expanded following its placement in the intervertebral space. The endplate comprises a pair of planks that are slidably received within respective recesses of a base portion of the endplate. During insertion of the implant into the intervertebral space, the planks are set in a contracted position within respective recesses of a base portion of the endplate. This provides the implant with a relatively small profile that is suitable for MIS procedures. Once the implant has been inserted, the planks are slid outward from the recesses to an expanded position that increases the footprint of the implant endplate. This expansion increases the stability of the implant.

摘要： Methods and devices are provided for retracting tissue. In one exemplary embodiment, a retractor is provided that includes a base, a plurality of blades extending from the base, and an actuator coupled to the base and operatively connected to the blades. The actuator can be configured to be actuated to move the blades relative to the base, thereby allowing the blades to retract tissue. The actuator can be self-locking so as to allow the blades to be freely movable within their entire range of motion relative to the base through actuation of the actuator without using another mechanism to lock the blades in a fixed position and to unlock the blades from the fixed position. The retractor can be formed from one or more radiolucent materials.

摘要： Methods and devices are provided for facilitating delivery and implanting of a bone anchor into bone. In one exemplary embodiment, a bone anchor extension is provided for coupling to a bone anchor to facilitate delivery and implanting of the bone anchor in bone. The bone anchor extension can have a generally elongate configuration that allows it to extend from a skin incision in a patient to a site proximate a patient's spine, and it can include a lumen extending therethrough between proximal and distal ends thereof. A distal end of the bone anchor extension can be adapted to engage a bone anchor, such as a bone screw. Various techniques are provided for locking the distal end of the bone anchor extension into engagement with a bone anchor.

摘要： 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.

摘要： An expandable trial can include an inferior portion, a superior portion, and a middle expanding portion as well as load cells for monitoring the load on the trial. The trial may also include recesses on its lateral sides to provide spacing to accommodate a disc removal tool so tissue can be cleared monitoring load. In addition, neural foramen spacing can be monitoring to provide information about how much neural release has been achieved as the disc is cleaned and the spine is positioned and repositioned.
