摘要: The invention is a pedicle screw assembly (10) for use with rod (11) the immobilization of bone segments. composed (12), poly-axial housing (20), washer (34), set (48), and cup shaped (40). When placed inside (21), head (12) comes into contact middle section (18), secured so that pivotable. includes pair upstanding posts (38) interior threads. A (24) inserted between rod. cap (40), having bottom openings (43) lateral cross connector (44), over (44) engages have semi-cylindrical engaging surfaces. (42) threaded to secure
