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