Abstract
A modular polyaxial bone screw that incorporates a threaded screw including a head portion and a tulip assembly that selectively “snaps” and locks onto the head portion of the threaded screw in a desired orientation. Thus, the threaded screw may be placed in bone before the tulip assembly is engaged onto the head portion of the threaded screw and a rod is disposed and secured there through using a locking cap, thereby locking the tulip assembly onto the head portion of the threaded screw in the desired orientation.
