摘要： Methods and devices are provided for replacing a spinal disc. In an exemplary embodiment, artificial disc replacements and methods are provided wherein at least a portion of a disc replacement can be implanted using a posterolateral approach. With a posterolateral approach, the spine is accessed more from the side of the spinal canal through an incision formed in the patient's back. A pathway is created from the incision to the disc space between adjacent vertebrae. Portions of the posterolateral annulus, and posterior lip of the vertebral body may be removed to access the disc space, leaving the remaining annulus and the anterior and posterior longitudinal ligaments in tact. The disc implant can be at least partially introduced using a posterolateral approach, yet it has a size that is sufficient to restore height to the adjacent vertebrae, and that is sufficient to maximize contact with the endplates of the adjacent vertebrae.

摘要： Various methods and devices for ligament replacement in the human body, and in particular, the spine are provided. In an exemplary embodiment, a ligament replacement system is provided that has an artificial ligament configured in the form of a closed loop. The artificial ligament is adapted to be coupled between the ligament seating regions of first and second connection members in a connection geometry that results in the artificial ligament having a large motion with a non-linear relationship between the force and displacement, similar to that of a natural ligament.

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： An intervertebral disc prosthesis comprises a left prosthesis component and a symmetric right prosthesis component positioned in an intervertebral space. Each prosthesis component includes a superior vertebra facing surface, an inferior vertebra facing surface, and a substantially spherical bearing surface. The bearing surface is positioned between the superior vertebra facing surface and the inferior vertebra facing surface. The superior vertebra facing surface is provided on a superior endplate and the inferior vertebra facing surface is provided on an inferior endplate. The superior endplate is operable to rotate relative to the inferior endplate upon the bearing surface. Each prosthesis component further comprises an elastic member positioned between an endplate and the bearing surface. The elastic member may be substantially cylindrical with a plurality of resilient ribs. Flexion/extension, lateral bending, and torsional movement are allowed by a combination of endplate rotation upon the bearing surface and compression of the elastic member.
