摘要： A bone screw assembly includes a screw body, including anchor portion and rod-receiving portion, and a rod seat movably mounted in the screw body to allow for controlled angulation between a spinal connection element disposed in the rod seat and the screw body. The rod seat is pivotable in one or more selected directions about one or more axes relative to the screw body. The rod seat may include a first lower rod seat element disposed in a recess of the screw body having a cylindrical bottom surface to facilitate pivoting in a first direction. A second lower rod seat element is stacked on the first lower rod seat element and has a conical bottom surface abutting a top surface of the first lower rod seat element to facilitate pivoting in a second direction.

摘要： A bone screw assembly includes an anchor portion and a head portion, such as a rod-receiving portion, movably mounted to the anchor portion to allow for controlled angulation between the anchor portion and the head portion. The anchor portion is pivotable in one or more selected directions about an axis relative to the head portion. A restriction member, which may be a rod seat, prevents the anchor portion from pivoting in one or more different directions about another axis relative to the head portion and/or a spinal fixation element received in the head portion. The restriction member may be inserted in the head portion to control direction that the anchor portion pivots relative to the head portion. The restriction member may also serve as a compression member and/or rod seat for seating a spinal rod coupled to the bone screw assembly.

摘要： A pelvic obliquity correction instrument and methods of use are provided. The pelvic obliquity correction instrument includes a first engagement arm for engaging a portion of a spinal fixation system where the first engagement arm is adjustably coupled to a handle assembly. The pelvic obliquity correction instrument also includes a second engagement arm for engaging a second portion of the spinal fixation system. A surgeon exerts force on a first grip at a first end of the handle assembly and a second grip at a second end of the handle assembly to reposition a patient's pelvic bone. The pelvic obliquity correction instrument may provide a surgeon with greater precision, control and torque when rotating a patient's pelvic bone with respect to a superior portion of the patient's spine.

摘要： Methods and devices are provided for connecting a spinal fixation construct to the spine, and preferably to the ilium and/or sacrum. In one exemplary embodiment, a spinal connector is provided having an elongate configuration with opposed thru-bores formed therein. Each thru-bore can be configured to receive a bone screw for attaching the spinal connector to bone. The spinal connector can also include a receiving portion formed thereon or removably mated thereto for mating a spinal fixation element, such as a spinal rod, to the spinal connector. In certain exemplary embodiments, the receiving portion can be positioned between the opposed thru-bores. In use, the spinal connector can be implanted in the sacrum and/or ilium and it can receive a laterally or horizontally extending spinal fixation element therethrough. The lateral spinal fixation element can mate to a longitudinal spinal fixation element which is mated to one or more vertebrae in a patient's spine, thereby anchoring a construct to the sacrum and/or ilium.
