Abstract
Provided is a novel multi-planar taper lock screw for connecting a connecting rod to bone. The screw is capable of multi-directional articulation while the connecting rod position can remain stable and aligned as needed. After the screw had been articulated and properly positioned, it can be locked such that the screw and the connecting rod will remain in relative position to the bone. The screw is configured for easy insertion and connection as well as easy removal and disconnection from the connecting rod. Also provided is a system for fixing two or more bones or bone fragments and a kit for fixing bones or bone fragments. A method of fixing bones or bone fragments is also provided.
