Abstract
A lock screw assembly for use with a pedicle screw assembly comprises a lock screw and an upper saddle. The lock screw includes a fastening tool engaging structure at a first end portion thereof and an upper saddle receiving structure at a second end portion thereof. The upper saddle is engaged with the upper saddle receiving structure of the lock screw in a manner allowing the upper saddle to rotate about a centerline axis of the lock screw. A plurality of intersecting spine rod receiving channels extend through a spine rod engaging portion of the upper saddle in a manner such that an outwardly-extending spine rod engaging structure is provided between adjacent ones of the spine rod receiving channels. Upper and lower surfaces of each spine rod engaging structure are acutely angled with respect to each other and wherein a channel edge defined between the surfaces is sharply pointed.
