摘要：
A fixing system for cervical vertebrae includes a fixing apparatus for cervical vertebrae in which a cervical vertebrae-fixing plate is made close contact with cervical vertebrae and a screw is inserted into the cervical vertebrae through a screw hole formed in the cervical vertebrae-fixing plate, and a driver that rotates the screw. Here, clips for holding the inserted screw are provided in the screw hole, a convex portion is positioned at the rear of a front end portion of the driver which is fitted in a groove on the screw, and the driver loosens the inserted screw while spreading the clips using the convex portion, when the inserted screw is loosened.
