Abstract
The cross connecting device includes a bar arm coupled to one of a pair of posterior rods or spinal fixation rods and a rod arm coupled to the other of the pair of the rods. The bar arm and rod arm are coupled together by a connector or coupling device. The coupling device has a shank extending through a bore in the bar arm and a connector bore through which a protrusion on the bar arm extends. The bar arm is rotationally movable in the connector bore. The shank is rotationally and translationally movable in the bar arm bore. The coupling device is vertically movable through the bore. The protrusion is rotationally and translationally movable in the connector bore. The cross connecting devices are coupled to the rods by a pair of opposing surface to surface contacts formed by a surface of a hook end and a surface of a pad.
