摘要: Instruments are provided for shifting elongate members, such as spinal rods, with respect to coupling members of spinal fixation systems. The instruments include a low friction drive mechanism having one or more rolling elements that ride along a helical groove or track in order to transform rotational movement of a drive member into linear shifting of a reducer member that shifts the elongate member. A one-way locking mechanism may be provided to selectively prevent unwanted counter-rotation of the low friction drive mechanism. The one-way locking mechanism may include annular ratchet teeth arranged on the exterior of the drive member and a ratchet pawl located adjacent to the teeth and selectively engageable therewith.

摘要: An implantable, spinal, vertebral replacement device comprises a tubular cage for fitting into a space left by a missing vertebral body and for optionally retaining bone graft material. First and second transverse plates are respectively positioned at opposed ends of the tubular cage for supporting the respective cage ends and for pressing a plate face against an adjacent vertebral body in spinal column-supporting relation. The transverse plates are each joined in transverse relation to a vertebral attachment plate which, in use, extends generally parallel to the spine. The vertebral attachment plate defines screw holes for preferably open helix screw securance to the pair of adjacent vertebral bodies that bracket the space left by the missing vertebral body.

First and second transverse plates are respectively positioned at opposed ends of the tubular cage for supporting the respective cage ends and for pressing a plate face against an adjacent vertebral body in spinal column-supporting relation. The transverse plates are each joined in transverse relation to at least one vertebral attachment plate which, in use, extends generally parallel to the spine. The vertebral attachment plate defines screw holes for screw securance to at least one vertebral body adjacent to the space. Preferably, one or more vertebral attachment plates are connected to the pair of adjacent vertebral bodies that bracket the space left by the missing vertebral body.

摘要: Instruments are provided for shifting elongate members, such as spinal rods, with respect to coupling members of spinal fixation systems. The instruments include a low friction drive mechanism having one or more rolling elements that ride along a helical groove or track in order to transform rotational movement of a drive member into linear shifting of a reducer member that shifts the elongate member. A one-way locking mechanism may be provided to selectively prevent unwanted counter-rotation of the low friction drive mechanism. The one-way locking mechanism may include annular ratchet teeth arranged on the exterior of the drive member and a ratchet pawl located adjacent to the teeth and selectively engageable therewith.
