摘要： An artificial disc having a pair of opposing plates for seating against opposing vertebral bone surfaces, separated by a wave washer having a circumferential extent surrounding a central bore. Various wave washer embodiments disclosed include circumferential extents that are ring-shaped, spiral-shaped, straight, bowed, grooved, wavy, thinning, thickening, and slotted. Various central bores disclosed include simple bores and bores that form a curvate socket. Various plate embodiments disclosed include plates having, on inwardly facing surfaces, a flat surface, a circular recess, or a ball-shaped protuberance that is mateable with the curvate socket. The wave washers 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.

摘要： 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.

摘要： An intervertebral spacer device includes first and second plates having plate surfaces, the first and second plates being spaced from one another with inner ones of the plate surfaces opposing one another and external ones of the plate surfaces facing in opposite directions. The spacer device includes at least one domed arch strip spring disposed between the inner surfaces of the first and second plate members for counteracting compressive loads applied to the external surfaces of the first and second plates. The at least one domed arch strip spring has lateral ends that are coupled with the first plate and a curvate central portion that is maintained adjacent the inner surface of the second plate.

摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a two-piece interlocking coupling element which mounts about the curvate head, and a rod receiving cylindrical body member having a tapered socket into which both the screw and the interlocking coupling element are securely nested. The interlocking coupling element includes a socket portion which is slotted and tapered so that when it is radially compressed by being driven downwardly into the tapered socket in the cylindrical body it crush locks to the screw. The securing of the rod in the body member provides the necessary downward force onto the socket portion through a contact force on the top of the cap portion. Prior to the rod being inserted, therefore, the screw head remains polyaxially free with respect to the coupling element and the body. In a preferred embodiment, the cap portion and the socket portion are formed and coupled in such a way that when the cap portion is compressed toward the socket portion, there is an additional inward radial force applied by the cap portion to the socket portion, thereby enhancing the total locking force onto the head of the screw.

摘要： An intervertebral implant includes a first plate having an inner surface, an outer surface, a ball shaped protuberance projecting from the inner surface and an annular groove surrounding the ball shaped protuberance. The implant includes a second plate having an inner surface, an outer surface, a curvate socket formed in the inner surface of the second plate and a raised rim surrounding the curvate socket. The first and second plates are assembled together so that the inner surfaces of the plates oppose one another and the ball shaped protuberance is disposed in the curvate socket and the annular groove aligned with the raised rim. The assembled first and second plates angulate and rotate relative to one another.
