    摘要： A bone screw system includes a bone screw and a connecting device for coupling the bone screw to an elongate rod-shaped member. The bone screw has proximal and bone-engaging portions disposed at opposing ends relative to a long axis of the screw. The proximal portion includes a proximal locking feature that extends away from the long axis in a radial direction that is perpendicular to the long axis. The connecting device includes first and second coupling portions at opposing ends relative to the long axis when the coupling device is assembled to the bone screw. The first coupling portion defines an opening for receiving the proximal portion of the bone screw. The second coupling portion is configured to receive the rod-shaped member. The connecting device also includes a restraining feature that frictionally resists rotational motion of the connecting device relative to the bone screw.

    摘要： An articular disc prosthesis and method of implanting the same within an intervertebral space between adjacent vertebral bodies. The prosthesis includes a pair of articular components and an articular ball disposed therebetween. Each of the articular components includes an outer shell portion and a removable inner insert portion. The insert portion includes a concave articular surface sized and shaped to receive a portion of the articular ball to provide articulating motion between the articular components. The outer shell portion includes a central hemi-cylindrical portion, a pair of laterally extending flanges, and an axially extending lip. Following removal of the natural intervertebral disc, a pair of hemi-cylindrical recesses are formed along a central region of the adjacent vertebral bodies to a predetermined depth. The prosthesis is implanted within the prepared disc space by axially displacing the hemi-cylindrical central portions of the articular components along the hemi-cylindrical recesses in the vertebral bodies. The lateral flanges and the axial lip of the articular components bear against the endplates of the adjacent vertebral bodies to stabilize the prosthesis and to prevent subsidence.

    摘要： A posterior arch prosthesis according to the present invention includes a main body, two transverse protuberances extending transversely from either side of the main body, articulating surfaces formed on each of the transverse protuberances, and a posterior protuberance extending posteriorly from the main body. The posterior protuberance is attached to a first vertebra from which the natural posterior arch has been removed such that the articulating surfaces are arranged in articulating contact with surfaces on an adjacent, second vertebra. The posterior protuberance includes an attachment to which native structure may be reattached upon attachment of the prosthesis to the first vertebra.

    摘要： An intervertebral prosthetic joint including a first articular component adapted to engage a first vertebra and a second articular component adapted to engage a second vertebra The articular components include abutting convex and concave articular surfaces that cooperate to permit articulating motion between the articular components. At least one of the convex and concave articular surfaces includes at least one surface depression that is configured to facilitate removal of matter disposed between abutting portions of the articular surfaces. In one embodiment of the prosthetic joint, each of the articular components has a vertebral bearing surface and a flange extending therefrom that is configured to penetrate a corresponding one of the first and second vertebrae, with the flange defining at least one opening extending therethrough to permit bone through-growth.
