    摘要： A posterior cervical fixation system including an occipital plate member, a cross connector, a pair of elongated spinal rods and a plurality of polyaxial screws. The occipital plate member configured for fixing to an occipital bone comprises an aperture to receive a bone anchor member to secure the occipital plate member to the occipital bone and at least one rod clamping element dimensioned to receive at least one spinal rod. The cross connector secures the pair of elongated spinal rods to vertebral bodies. The cross connector includes a pair of collet connectors and a cross bar that is configured to secure the pair of elongated spinal rods in a desired distance. Each polyaxial screw has an anchor head associated with a fastening member. The pair of elongated spinal rods is configured to extend along the vertebral bodies between the occipital plate member and at least one of the polyaxial screws.

    摘要： An interspinous process device is configured for placement between adjacent spinous processes on a subject's spine. The device includes a housing configured for mounting to a first spinal process, the housing having a lead screw fixedly secured at one end thereof. A magnetic assembly is at least partially disposed within the housing and configured for mounting to a second spinal process. The magnetic assembly includes a hollow magnet configured for rotation within the magnetic assembly, the hollow magnet comprising a threaded insert configured to engage with the lead screw. An externally applied magnetic field rotates the hollow magnet in a first direction or a second, opposite direction. Rotation of the hollow magnet in the first direction causes telescopic movement of the magnetic assembly out of the housing (i.e., elongation) and rotation in the second direction causes telescopic movement of the magnetic assembly into the housing (i.e., shortening).

    摘要： An osseous anchorage implant comprising an attachment structure adapted to receive and be attached to at least one bar, that is suitably an element of an osteosynthesis. The implant is made up of an osseous anchor and an attachment head bearing the attachment means. The attachment head is suitably traversed by a channel that is adapted to receive the bar. The attachment head comprises a clamp that is adapted to clamp the bar against an inside support wall of the channel. The implant is further characterized by the attachment means and the support wall enabling the rotation of the bar about a first axis that is not parallel to the longitudinal axis of the bar. The clamp comprises a moving clamping face, that is adapted to contact the bar, and that is borne by a support head that is articulatable at the end of the clamp via a ball and socket connection. The channel is suitably an open channel having an aperture opening onto one of the lateral faces of the attachment head, wherein the aperture bears the clamp. The bar is enabled to be introduced into the channel from a side of the channel.
