摘要： A spinal disc prosthesis (10) to replace a damaged spinal disc in a spinal column (16) of a human, includes an elastomeric core (200) having upper and lower surfaces (202, 212) which are parallel to each other. An upper rigid plate (20) has opposed first and second surfaces (42, 52). The first surface (42) is affixed to the upper surface (202) of the elastomeric core. The second surface (52) is inclined relative to the first surface (42). A lower rigid plate (120) has opposed third and fourth surfaces (142, 152). The third surface (142) is affixed to the lower surface (212) of the elastomeric core (200) and extends parallel to the first surface (42). The fourth surface (152) is inclined relative to the third surface (142). The second and fourth surfaces (52, 152) are inclined relative to each other.

摘要： A method and apparatus is provided to retain elements of the spine and/or pelvis in a desired spatial relationship. A plurality of fasteners are connected with a plurality of the elements. A longitudinal member is connected with the fasteners by a plurality of connector members. The longitudinal member and fasteners are movable relative to each other to adjust the distance between the longitudinal member and fasteners to thereby obtain the desired spatial relationship between the longitudinal member and elements to which the fasteners are connected. Once the longitudinal member and fasteners have been positioned in the desired spatial relationship, clamps are engaged to hold the longitudinal member, fasteners and connector members against relative movement. To provide for the adjustability of the longitudinal member relative to the fasteners, oblong openings are formed in the connector members. In one specific method of adjusting the position of the longitudinal member relative to the fasteners, the longitudinal member is rotated about an axis which extends through a portion of the longitudinal member.

摘要： A spinal disc prosthesis comprises an upper rigid plate, a lower rigid plate, and an elastomeric core interposed between the plates and adhered to the plates. The elastomeric core has an upper portion with an outer peripheral surface extending substantially perpendicular to the upper plate. A lower portion of the elastomeric core has an outer peripheral surface extending substantially perpendicular to the lower plate. An intermediate portion of the elastomeric core, extending between the upper and lower portions, has a concave outer peripheral surface. Each of the upper and lower plates has a plurality of ribs extending into the elastomeric core to secure the elastomeric core to the upper and lower plates.

摘要： A method of fusing together the adjacent vertebrae using the spinal implant includes removing at least a portion of the spinal disc between the adjacent vertebrae. The spinal implant is inserted between the adjacent vertebrae with the first and second parallel side surfaces facing the adjacent vertebrae. The spinal implant is rotated into a position in which the parallel side surfaces extend from one of the adjacent vertebrae to the other adjacent vertebrae and the upper and lower surfaces engage the adjacent vertebrae.

摘要： An apparatus for use in retaining spinal elements in a desired spatial relationship includes a fastener for engaging a spinal element. A longitudinal member is positionable along the spinal column. A connector member interconnects the fastener and the longitudinal member. The connector member has a mounting section with surface means defining a first opening through which the fastener extends. The longitudinal member extends through a second opening in the connector member. The axis of the opening through which the longitudinal member extends is perpendicular to top and bottom surfaces of the connector member. The mounting section has a side surface extending at an acute angle to the top and bottom surfaces. The connector member includes a surface that is parallel to the longitudinal axis of the opening through which the longitudinal member extends. The side surface of the mounting section extends at an acute angle to the surface of the connector member which is parallel to the longitudinal axis of the opening through which the longitudinal member extends.

摘要： An apparatus for use in retaining a longitudinally extending member in position relative to a spinal column includes a top-entry hook assembly having a hook portion which is engageable with a spinal column. A body extending upwardly from the hook portion and has an open ended recess which extends through the body and is open along one side to enable a rod or longitudinal member to be moved into the recess through the open side. An end cap is engageable with the body to close the upper side opening. A clamp member or set screw is disposed at the center of the end cap to clamp the rod in the recess in the body. The end cap and body are interconnectable by different types of connectors including a bayonet connector, a linear cam connector, or a threaded connector.

摘要： A spinal disc prosthesis comprises an upper flat rigid plate, a lower flat rigid plate, and a flat elastomeric core interposed between said plates and adhered to the plates. A plurality of spaced-apart protuberances extend outwardly from the exposed faces of the plates for engagement with vertebrae above and below the plates. A porous coating covers the exposed surfaces of the plates. The elastomeric core is made of a polyolefin rubber having mechanical properites similar to a natural spinal disc.

摘要： An improved fastener is provided for use in retaining vertebrae in a desired spatial relationship. The fastener has a mounting section with a first external thread to engage a vertebra. The fastener has a retaining section with a second external thread to engage an internal thread on a retaining element, such as a nut. A pair of parallel flats are formed on opposite sides of the retaining section. The flats are spaced apart by a distance which is substantially the same as or greater than a root diameter of the external thread on the retaining section. A driving recess in an axially outer end of the retaining section has arcuate corner portions which receive force to effect rotation of the fastener relative to a vertebra engaged by the mounting section. The arcuate corner portions of the driving recess are offset from a plane containing the longitudinal central axis of the retaining section and extending perpendicular to the flats.
