Abstract: Reamer instruments and related methods are disclosed herein, e.g., for reaming bone to facilitate in situ assembly of a bone anchor. In some embodiments, the instrument can include a feedback mechanism configured to alert the user when sufficient bone has been removed to facilitate assembly of the bone anchor. The feedback mechanism can be triggered by a movable shaft of the instrument that is displaced by the shank portion of the bone anchor as the surrounding bone is reamed.

Abstract: Bone anchor assemblies and related instrumentation are disclosed herein. In some embodiments, a modular bone anchor assembly allows for a bone anchor to be driven into bone and a head or receiver member to be attached thereto at some later point in time. The bone anchor can have a smaller footprint than the complete assembly, which can improve visualization and anatomical spatial awareness during insertion of the bone anchor and during other surgical steps performed prior to attaching the head or receiver member to the bone anchor. A variety of modular head types are disclosed, as are various instruments for driving a bone anchor, attaching a head to a bone anchor, removing a head from a bone anchor, and making a unilateral attachment to a head of a bone anchor assembly. Drive interfaces for driving a bone anchor are disclosed, as are features that allow a bone anchor to act as a fixation point for soft tissue retraction, disc space distraction, derotation, and the like.

Abstract: A method of providing access to an intervertebral disc has been developed that involves using the patient's bony pedicle as an anchoring spot for a pedicle screw that temporarily attaches to the access port. Because this new procedure eliminates the need for the surgical table as an anchor, it also eliminates the assembly components extending from the table to the port at the access site, thereby unencumbering the surgeon's view and workspace while providing minimally invasive access.

Abstract: A method of providing access to an intervertebral disc has been developed that involves using the patient's bony pedicle as an anchoring spot for a pedicle screw that temporarily attaches to the access port. One key element of the method is an assembly comprising: a) a screw extension comprising a shaft having a distal end portion comprising a receiver adapted for receiving a screw and a proximal end portion comprising a pivoting feature, b) a port comprising: i) a tubular wall defining a central passageway, ii) a longitudinal slot in the wall defining opposed ends of the wall, iii) opposed flanges extending radially from each end of the wall, and iv) a mating feature disposed in each opposed flanges adapted to pivotally mate with the pivoting feature of the screw extension, wherein the mating feature of the tube pivotally mates with the pivoting feature of the screw extension.

Abstract: Various bone screws configured to be implanted into bone and methods of use are provided. In an exemplary embodiment, a bone screw is provided with an elongate shank and a head with a drive feature configured to couple with a driver tool for being advanced into bone and a threaded shank. The screw can have a distal end or tip that has one or more cutting edges thereon configured to cut bone as the bone screw is inserted into bone.

Abstract: A vertebral manipulation assembly includes a vertebral fixation assembly that is configured to be attached to a first vertebra and a second vertebra that is spaced from the first vertebra. The vertebral fixation assembly can include vertebral fixation members that attach to the first and second vertebrae, respectively. The vertebral manipulation assembly can further include a vertebral manipulation instrument that is configured to be coupled to the vertebral fixation assembly, and provide a first compression force that biases the first and second vertebral fixation members to move toward each other, and a second distraction force that biases the first and second vertebral fixation members to move away from each other. The vertebral manipulation instrument can include a coarse adjustment assembly that, when actuated, causes the first and second vertebral fixation members to incrementally move with respect to each other in first increments.
