Abstract: A screw and coupling element assembly for use with an orthopedic rod implantation apparatus includes a screw with a head and a shaft extending from the head, a coupling element with a seat within which the head is seatable such that the shaft protrudes from the coupling element, and a locking element mateable with the coupling element and when mated is selectively movable through a plurality of positions including unlocked and locked positions. When in the unlocked position, the locking element presents a rod-receiving channel and the head is movable in the seat such that the shaft is directable in a plurality of angles relative to the coupling element. When in the locked position, a rod disposed within the rod-receiving channel is fixed relative to the coupling element and the head is immovable in the seat such that the shaft is fixed at an angle relative to the coupling element.

Abstract: An artificial intervertebral disc having a pair of opposing plate members for seating against opposing vertebral bone surfaces, separated by a spring mechanism. The preferred spring mechanism is at least one spirally slotted belleville washer having radially extending grooves. One plate member has a centrally located ball-shaped protrusion that is rotatably coupled in a central socket in the narrow end of the belleville washer, and the wide end of the belleville washer is held against the other plate member by a shield with rivets. Therefore, the disc assembly will not come apart under tension loads applied to the plate members, and the location of the ball joint coupling provides the disc assembly with a centroid of motion that is centrally located between the vertebral bone surfaces, both causing the disc assembly to behave similarly in these respects to a healthy natural intervertebral disc.

Abstract: An artificial disc having a pair of opposing plates for seating against opposing vertebral bone surfaces, separated by a spider spring having a plurality of spring arms extending radially from a central hub. Various spring arm embodiments disclosed include spring arms that are straight, bowed, grooved, wavy, thinning, or thickening; and spring arms with parallel sides, radially outwardly diverging sides, or radially outwardly diverging and curving sides. Various spider spring embodiments disclosed include spider springs with central hubs that are solid, bored, have curvate sockets, or have semispherical protuberances. Various plate embodiments disclosed include plates having, on inwardly facing surfaces, a curvate socket, a semispherical protuberance, a circular recess, or a flat surface. The spider springs are disposable between the plates, through various disclosed couplings, so that the plates compress, rotate and angulate freely relative to one another, enabling the artificial disc to mimic a healthy natural intervertebral disc.

Abstract: An intervertebral spacer device having a pair of opposing plates for seating against opposing vertebral bone surfaces, separated by at least one spring mechanism. A first plate of this embodiment includes a post extending upwardly from the inner surface of the plate, the post including a ball-shaped head. The post is designed to flexibly support a slotted belleville washer, which can be selectively mounted to the head such that the wider portion of the washer seats against the second plate. Compression of the assembly causes a deflection of the slotted belleville washer. The slotted belleville washer of this invention has a radially varying thickness which permits the load deflection profile to mimic that of the natural cartilage which is being replaced.

Abstract: An intervertebral spacer device having a pair of opposing plates for seating against opposing vertebral bone surfaces, separated by at least one spring mechanism. The preferred spring mechanism is an arched strip spring. In a first embodiment there are multiple springs positioned independently about the area of the opposing plates. In a second embodiment there is a single arched strip spring modified to mount onto a ball-shaped head. The lower plate of this second embodiment includes a post extending upwardly from the inner surface of the plate, the post including a ball-shaped head. The spring and post members are flexibly coupled such that the upper and lower plates may rotate relative to one another.
