    摘要: Provided is an offset dynamic motion system. In one example, the system includes an offset member having a rod connecting a shaped portion to a threaded portion, where a longitudinal axis of the threaded portion is angled relative to a longitudinal axis of the rod and the shaped portion is configured to couple to a polyaxial head. A first dynamic member is configured to rotationally couple to another polyaxial head. A second dynamic member is configured to rotationally couple to the threaded end of the offset member and to slideably receive part of the first dynamic member.

    摘要: Provided is a system for dynamically stabilizing a spine. In one example, the system includes a first bone anchor coupled to a first polyaxial head and a second bone anchor coupled to a second polyaxial head. An axis passing through a center of each polyaxial head is aligned with a center of rotation. A first member has a first end movably coupled to the first polyaxial head and a second end. A second member has a third end coupled to the second polyaxial head and a fourth end moveably coupled to the second end. The first and second members are configured to maintain the alignment of the axes with the center of rotation during three dimensional movement of the first member relative to the second member.

    摘要: Provided are a system and method for a spinal implant locking assembly. In one example, the system includes a bone anchor, a polyaxial head coupled to a proximal end of the bone anchor, a spinal implant, and a locking assembly. The locking assembly may have a bearing post with a distal portion coupled to the polyaxial head and a proximal portion that extends through an opening in the spinal implant. The locking assembly may also have a bushing, a bearing element, and a threaded locking member. The threaded locking member may be configured to rotationally engage a threaded surface on at least one of the bearing post and the bushing.

    摘要: A dynamic motion component for a spinal implant is provided, comprising a first rod coupled to an enclosure and a second end of a second rod captured in a cavity of the enclosure. A dampener unit surrounds a captured portion of the second end and is positioned between the first end and the second end. In response to pivotal or translational movement of the second rod relative to the first rod, the dampener unit is compressed against one or more inner surfaces of the cavity to provide for progressive resistance of movement of the second rod.
