Box cage for intervertebral body fusion |
摘要 |
An interbody implant for enhancing fusion of adjacent vertebral bodies comprises a rectangular cage member of an open construction dimensioned to fit between adjacent vertebral bodies following surgical removal of the disk. The rectangular cage member includes a plurality of ribs for engaging the plateaus of adjacent vertebral bodies for preventing lateral shifting of the cage. It is held against anterior/posterior motion by a locking screw which threadedly engages the cage and adjacent bone tissue. The cage is adapted to be packed with bone graft material for enhancing solid bone fusion.
