Abstract: The present application discloses methods for treating spinal deformities. One embodiment includes inserting an elongated corrective member into the patient. During insertion, the corrective member is operatively attached to a first vertebral member that applies a first corrective force to correct a first vertebral member alignment. The corrective member is further inserted into the patient and subsequently operatively attached to a second vertebral member that applies a second corrective force to correct a second vertebral member alignment. The corrective member is further inserted and subsequently operatively attached to a third vertebral member that applies a third corrective force to correct a third vertebral member alignment. The embodiment may further include operatively attaching the corrective member to additional vertebral members to correct further misalignment. In one embodiment, a second member is attached to the vertebral members after they have been aligned to maintain the alignment.

Abstract: Stabilizer of the spinal column adapted to connect to each other at least two adjacent vertebrae using flexible connection elements that allow for some limited motion to the vertebrae and/or stiff connection elements, further comprising an elongated block, stiff or flexible, having two ends operatively connected or compressed between the heads of two screws connected to adjacent vertebrae, the head being obtained separated from the screw, and the head and the screw being componible together through engaging means, the head having a first through hole for housing a resilient tie-member connected between two heads and adapted to keep the block in position, the head having a second through hole, at an angle with respect to the first hole, adapted to house a transversal tie-member connecting diagonally, with respect to the spinal column, the heads of two screws being applied to two consecutive vertebrae.
Abstract: A cage device is disclosed that includes, in one embodiment, a body and a pair of pedicle tabs attached thereto and potentially for connecting other orthopedic devices, such as anchors, screws, or rods, to the vertebral body replacement and potentially other vertebrae. The body also has a central opening for receiving orthopedic devices and/or osteogenic material.
Abstract: A spinal stabilization system includes a first stabilization member and a second stabilization member engaged to one another in end-to-end fashion. A flexible coupling member allows the spinal stabilization members to be assembled and attached to the spinal column to dynamically support of the stabilized levels of the spinal column.
Abstract: A stabilization system for a human spine is provided. The stabilization system may include two dynamic interbody devices and/or one or more dynamic posterior stabilization systems. The dynamic interbody devices may be inserted into a disc space using a posterior approach. The dynamic interbody devices may allow for coupled axial rotation and lateral bending of vertebrae adjacent to the dynamic interbody devices. The dynamic posterior stabilization systems may provide resistance to movement that mimics the resistance provided by a normal functional spinal unit.

Abstract: A bio-compatible stabilization system includes one or more inserters and a connector for traversing a space between one or more bony structures. The stabilization system is designed to reduce or eliminate stress shielding effects while functioning as a tension band. The connector includes an extendable member and an over-extension limiter that limits extension of the extendable member.

Abstract: A dynamic spinal stabilization assembly includes at least one mounting collar with a bore therethrough along a longitudinal axis, and a spinal rod slidably extending through the bore. The bore includes a medially disposed first section of reduced size that tapers both inwardly and outwardly relative to the axis, and respective end sections of relatively larger size. The bore may be defined by an interior wall that convexly curves toward the axis in the first section, advantageously with a constant non-zero radius of curvature. The bore profile helps minimize potential binding that may occur between the collar and the rod. The rod is coupled to bone anchoring elements, with at least one such connection being via the collar.

Abstract: A system and associated method are provided for mechanically fixating a region of a skull to a portion of a spine. A plate is provided to contact a region of a skull and be secured thereto. A spinal rod is configured to extend from a location adjacent the plate to a location adjacent at least one vertebra. An adjustable housing is provided to secure the rod to the plate, and has a first position wherein the relative position of the rod to the plate can be adjusted and a second position wherein the relative position of the rod to the plate is secured.

Abstract: A connector device for a spinal stabilization apparatus comprises a first elongated member having first and second ends, and is adapted to engage a first spinal stabilizer rod proximal to the first end of the elongated member and is further adapted to engage a spinal cross connector rod proximal to a second end of the first elongated member. The first end of the first elongated member comprises a hook shape and a ferule and may engage the first spinal stabilizer rod within about 20 degrees of perpendicular to the spinal stabilizer rod in any direction. The ferule is adapted to be seated within the hook shape and is further adapted to engage the first spinal stabilizer rod. A second elongated member substantially similar to the first may additionally be used in a spinal stabilization apparatus. The connector device may be used in a method of treating a patient.
Abstract: Various methods and devices are provided for connecting spinal fixation elements, such as spinal rods, implanted in a patient's spinal column. In particular, various spinal cross connectors are provided for connecting to one or more spinal fixation elements implanted in a patient's spine. The cross connectors can have a variety of configurations, including a fixed or adjustable length, as well as various features that allow certain portions of the cross connectors to be angularly oriented.
