    摘要： The present invention provides a minimally-invasive surgery pedicle screw and rod assembly, inserter tool, and insertion method for use in spinal stabilization procedures and the like. The screw and rod assembly utilizes a screw head body that has a pair of tab extenders that extend longitudinally from the head body to a point well outside of the skin and musculature of the patient. A rod is coupled to and translated along these tab extenders, ultimately into proximity with the head body. The rod is inserted into, aligned with, and translated along the length of the tab extenders, and then selectively pivoted about an enlarged partial spherical bearing into a configuration that is substantially perpendicular to the tab extenders and the head body. The present invention also provides an inserter tool that is used to dispose the rod concentrically within the tab extenders, translate the rod along the length of the tab extenders, and then pivot the rod with respect to the tab extenders and the head body.

    摘要： A polyaxial bone anchor assembly, comprising: a threaded screw portion comprising a head end; a head body disposed concentrically about the head end of the threaded screw portion; and a saddle assembly disposed within the head body and selectively engaging the head end of the threaded screw portion; wherein, when the saddle assembly is translated within the head body into a first locked position, the head body is coupled to the threaded screw portion such that disengagement of the head body from the threaded screw portion is allowed; and wherein, when the saddle assembly is translated within the head body into a second locked position, the head body is coupled to the threaded screw portion such that disengagement of the head body from the threaded screw portion is prevented.
