Abstract
Provided is a novel uni-planar taper lock screw for connecting a connecting rod to bone. The screw is capable of being secured to the underlying bone while the screw head adapted to securely hold a connecting rod is articulated in a uni-directional manner to facilitate a stable connection to the connecting rod. After the screw had been articulated and properly positioned, it can be partially locked such that the connecting rod will remain in relative position to the bone while permitting flexibility of the screw head relative to the bone along a single plane. The screw head can then be fully locked securing the connecting rod into a selected position. 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.
