Abstract
A posterior fixation system includes a saddle member and an anchoring member. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The saddle member further has a hole therethrough bounded by an inner wall, and the hole forms a lower opening in the saddle member. The lower opening in the saddle member may contain angular cutouts placed symmetrically about the axis of the saddle to increase the allowable angulation of the bone screw in relationship to the axis of the saddle. The channel is adapted to receive an orthopedic rod, and the hole in the saddle member is adapted to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members.
