    • In one embodiment of the present invention a system for connecting a fastener element (e.g., a pedicle screw) relative to a rod for the purposes of vertebral fixation is provided. The system may permit multi-aerial movement between the fastener element and the rod. Further, the system may permit the angular relationship between the fastener element and the rod to be held in a desired orientation. For the purposes of describing and claiming the present invention, the term "rod" is intended to refer to any elongated structure. Such an elongated structure may be solid or hollow and may have any desired cross-section (e.g., circular, oval, square, rectangular). Further, for the purposes of describing and claiming the present invention, the term "interference fit" is intended to refer to physical contact between two or more components.
    • 在本发明的一个实施例中,提供了一种用于为了椎体固定的目的而相对于杆连接紧固元件(例如,椎弓根螺钉)的系统。 该系统可以允许在紧固元件和杆之间进行多空中运动。 此外,系统可以允许将紧固件元件和杆之间的角度关系保持在期望的方位。 为了描述和要求本发明的目的,术语“杆”旨在表示任何细长结构。 这种细长的结构可以是实心的或中空的,并且可以具有任何期望的横截面(例如,圆形,椭圆形,正方形,矩形)。 此外,为了描述和要求本发明的目的,术语“干涉配合”旨在表示两个或更多个部件之间的物理接触。
