All iliac hone graft fused well and a great deal of bony callus was found the vertebral body surface. Lucency area was in seen surrounding the hone graft, titanium and AC-AFF on the X-ray films, and there wan new bone formation in the interface of internal union and bone. The central region of titanium and AC-AFF became vague and new bone formation was found in the intracavitary aim of implants by CT scan. And port of the new hone transited the parietal reticulation and connected with normal ones at titanium and AC-AFF.
