摘要: A spinal fixation device includes a bone screw, a nut, a bearing, a slider, and a plate construct. The screw has a head with a nut connection and a screw portion. The nut has an exterior wall and a bore connecting to the nut connection. The bearing has an exterior and defines a bore fitting therein the nut connection and the exterior wall of the nut. The slider defines a bore fitting the nut exterior wall therewithin and has an exterior with a given shape. The elongate plate construct has a first end defining a first opening shaped to accept the exterior of the bearing therein and a second end defining a second opening shaped to accept the slider therein and having a corresponding shape to the given shape to permit the slider to slide in at least a portion of the second opening.
