The rectangular cage (30) member includes a plurality of ribs (40) for engaging the plateaus of adjacent vertebral bodies (10, 12) for preventing lateral shifting of the cage (30). It is held against anterior/posterior motion by a locking screw (48) which threadedly engages the cage (30) and adjacent bone tissue. The cage (30) is adapted to be packed with bone graft material (21) for enhancing solid bone fusion.</p> |
