A total of 54 patients with cervical disc disease who underwent vertebral column autograft with the intervertebral disc were studied before and after surgery by flexion/extension cervical X-ray film and MRl. 46 patients were operated on at one level and 8 patients were operated on at two levels. Postoperative X-ray film showed some movement in the operated disc level in all patients (average postoperative follow up period was 27 months, ranging over a period of 1 year to 4 years 1 month). A significant decrease in motion in the extension position was observed postoperatively (P<0.0001), but there was no significant difference between the preoperative motion and postoperative motion in the flexion position. Our postoperative MRl examination showed no degenerative changes because a high intensity of implanted intervertebral disc tissue was preserved. However, because the observation periods were short, further follow up research is required to confirm the extent of the preservation of implanted tissues.
