Abstract:
1. A system for adjusting a distance between vertebral bodies of a human spine, comprising: a first extender configured to detachably couple to a first bone fastener assembly that is securable to a first vertebral body; a second extender configured to detachably couple to a second bone fastener assembly that is securable to a second vertebral body, wherein one of the first and second bone fastener assemblies secures to a rod so as to inhibit movement relative to the rod, and the other of the first and second bone fastener assemblies is movably coupled to the rod to allow movement along the rod relative to the secured bone fastener assembly; and an adjuster having: wherein actuation of the first handle relative to the second handle at a pivot point forces the extender that is coupled to the bone fastener assembly movably coupled to the rod to move towards the extender that is coupled to the bone fastener assembly secured to the rod, whereby the bone fastener assembly movably coupled to the rod is forced to move towards the bone fastener assembly secured to the rod, causing compression of the first and second vertebral bodies.
