An intervertebral fusion cage having a plate pivotally attached thereto. The plate and cage are pivotally coupled but move independently of each other. The plate is made up of two smaller plate halves: a superior plate half and an inferior plate half. Both plate halves form the larger plate. The plates are joined using a cross pin that provides a pivot point about which the plate halves rotate. The same pin also joins the plate halves to the cage, thus allowing the plate halves to pivot about the cage. It is believed that the device of the present invention will reduce the difficulties in placing a lateral plate down a port and manipulating it into position. Mating the plate to the cage will reduce the chances of micromotion and improve fusion rate, resulting in improved patient outcomes.
