Abstract: The present invention relates to a spinal fusion cage which is inserted between vertebral bodies in a state where the cage has the lowest height and is height-adjustable in the inserted state, thus making it possible to replace cages having heights in a certain range by a single cage. Therefore, manufacturers can reduce product groups that need to be produced and can also reduce product stock. Further, in contrast to the conventional cages having predetermined heights at regular intervals, the height of the inventive cage can be linearly adjusted according to the distance between the vertebral bodies of a patient, and thus a surgery for the patient can be performed using the cage adjusted to an optimum height according to the patient's condition.

Abstract: Disclosed is an intervertebral fusion cage which may be inserted between vertebrae from which a disk is removed to restore and maintain an interval between two vertebrae, and more specifically, to an intervertebral fusion cage having an easily mountable shape while enlarging a contact area with blood in a spinal cavity during surgery. A intervertebral fusion cage 100 generally includes a front part 102, first and second side parts 106 and 108 connected to both ends of the front part 102, and a rear part 104 connected to the pair of first and second side parts 106 and 108, wherein the front part 102, the first and second side parts 106 and 108 and the rear part 104 define fixing holes 130 and 132 therein which are vertically opened.
