    • 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.
    • 一种模块化多轴骨螺钉,其包括螺纹螺钉,该螺纹螺钉包括头部和郁金香组件,所述头部部分和郁金香组件选择性地“按压”并以期望的方向锁定在螺纹螺钉的头部上。 因此,在将郁金香组件接合到螺纹螺钉的头部之前,螺纹螺钉可以放置在骨头中,并且通过使用锁定帽将杆设置并固定在其上,从而将郁金香组件锁定到螺纹的头部 拧上所需的方向。
