Abstract: An intervertebral spacer device having a pair of opposing plates for seating against opposing vertebral bone surfaces, separated by a spring mechanism. The preferred spring mechanism is a slotted domed arch strip spring which is coupled to the upper plate by set screws. The spring includes a socket formed in the peak thereof and mounts onto a ball-shaped head extending outwardly from the lower plate. The spring and post members are thereby flexibly coupled such that the upper and lower plates may rotate relative to one another.

Abstract: A porous intervertebral spacer having a flexible wire mesh as a vertebral body contact surface, the flexible wire mesh preferably being a convex titanium mesh laser-welded at its perimeter to the spacer. The mesh is domed in its initial undeflected conformation, but deflects as necessary during insertion of the spacer between vertebral bodies, and, once the spacer is seated between the vertebral bodies, deforms as necessary under anatomical loads to reshape itself to the concave surface of the vertebral endplate, providing gripping and holding strength upon initial implantation, and an osteoinductive surface through which the bone may ultimately grow, making the fixation of the spacer between the vertebral bodies secure.

Abstract: 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.

Abstract: An orthopedic device including a longitudinal plate assembly having an adjustable length and two ends. Each of the ends includes a feature that can be used to couple the end to a body structure, such as, for example, a vertebral bone. Preferably, the assembly includes two longitudinal plates that can translate longitudinally with respect to one another through a plurality of positions and be secured with respect to one another at one of the positions, thereby enabling the length of the assembly to be adjusted. Inasmuch as the length of the plate assembly can be adjusted, the surgeon can set the length to the most clinically appropriate length for effective coupling of the plate assembly to the body structure.

Abstract: A screw and coupling element assembly for use with an orthopedic rod implantation apparatus includes a screw that has a head and a shaft that extends from the head, a coupling element that has a seat within which the head can be seated such that the shaft protrudes from the coupling element, and a locking element that can be mated with the coupling element and that thereafter can be selectively moved through a plurality of positions including an unlocked position and a locked position. When the locking element is in the unlocked position, the locking element presents a rod-receiving channel and the head is movable in the seat such that the shaft can be directed in a plurality of angles relative to the coupling element. When the locking element is 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: 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.

Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate ball top, a polyaxial head member having a socket into which the head of the screw is initially polyaxially nested, a vertical slot which renders the socket compressible, and a horizontal through hole having a tapered portion on one side of the vertical slot. A rod gripping cross-bar member, which is mounted through the through hole includes an axial split which permits the first end thereof to grip a rod, and then to be clamped onto the rod when the axial slot is narrowed. A nut is provided on the end of the cross-bar member which extend out from the through hole on the opposite end from the rod gripping mechanism. The advancement of the nut causes the cross-bar member to be compressed by the taper of the front portion of the through hole, thereby locking the rod in the gripping end thereof, and further provides the compression force necessary to compression lock the interior socket of the head against the ball top of the screw.

Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a cross bar mounting element having a socket into which the head of the screw is initially polyaxially nested. The cross bar mounting element further includes a vertical split which permits the socket to be expanded or compressed via the application of a corresponding force directed at the split. The cross bar mounting element further includes a pair of upwardly extending members which define a trough into which a cross bar element is positioned. The cross bar element includes features which permit the secure fixation of a rod thereto, as well as a selectively slideable element, such as a nut, which may be tightened to apply the compressive force necessary to compress the interior volume onto the head of the screw, thus locking the assembly in place.
