摘要： A system for reduction of vertebral bodies (or vertebrae) in various embodiments includes a reducer, and extender, and a hollow tube. The reducer couples to the extender, which in turn couples to an elongated member, such as a rod, and to a bone fastener assembly. The reducer allows reduction of the vertebral body incrementally, and by a desired amount. The reducer may include or may be used in conjunction with a holding device or holder in order to hold or keep the amount of reduction constant or steady once the desired amount of reduction has been obtained. The reducer may use one of several embodiments, including embodiments that use threaded assemblies or members, inclining members or wedges, offset cams, scissor jacks, and/or levers.

摘要： A spinal stabilization system includes bone fastener assemblies to be coupled to vertebrae. Each bone fastener assembly includes a bone fastener (100) and a collar (200). The bone fastener has a head portion (102) having at least a first cross-sectional shape in a first plane, and a second cross-sectional shape in a second plane. The collar has a circular opening (210) in the bottom, with a relief (212) extending from the circular opening. The second cross-sectional shape of the bone fastener is keyed to the opening to permit insertion of the bone fastener into the collar assembly, from the bottom. After insertion, the bone fastener is rotated to prohibit removal of the bone fastener from the collar. The collar can then be rotated and/or angulated relative to the bone fastener. An elongated member can be positioned in the collar and a closure member is then used to secure the elongated member to the collar.

摘要： A spinal fixation implant system for correction and fixation of the human spine to facilitate an anatomically correct fusion. The spinal fixation system may include a connector, a spinal rod, a spinal fixation component, a sleeve, and a fastener. The spinal fixation component preferably includes a fixation device such as a hook or screw for securing the spinal rod to vertebrae of the thoracic or lumbar spine. The spinal fixation component preferably includes a threaded end on its top that is adapted to receive the fastener. The fixation component may include a body having a tapered cavity for engaging the receiving end of the connector. Tightening of the fastener preferably downwardly translates the sleeve over the fixation component body to force the connector through the tapered cavity, which compresses the receiving end about the spinal rod to fixation connect the spinal rod and the spinal fixation component. In an alternate embodiment, assembly pliers may be used to move the connector into the tapered cavity. The fixation component may also include a rotatable fixation member.

摘要： A system and associated method are provided for mechanically fixating a region of a skull (102) to a portion of a spine (104). A plate (200) is provided to contact a region of a skull (106) and be secured thereto. A spinal rod (600) is configured to extend from a location adjacent the plate (200) to a location adjacent at least one vertebra (108). An adjustable housing (300) is provided to secure the rod (600) to the plate (200), and has a first position wherein the relative position of the rod to the plate can be adjusted and a second position wherein the relative position of the rod to the plate is secured.

摘要： A spinal plate system (30) that maintains intervertebral spacing and spinal stability is provided. In an embodiment, a spinal compression plate (30) may include two or more plates (32, 34) coupled together form an adjustable-length plate. Movement of plates (32, 34) in a spinal compression plate (30) may be uni-directional. Compression of a spinal compression plate movement may mimic natural settling of bones in a spine and/or distribute at least a portion of a vertebral load to an implant positioned between two vertebrae. Maintaining at least a portion of the vertebral load on an insert may increase bone growth and increase fusion between an implant and surrounding vertebrae.
