Three hundred and twenty six cases with spinal diseases (209 noninfectious and 117 infectious) were treated by anterior interbody fusion.

Preoperative plain radiography vvas done and the periodic plain radiography was performed every three month postoperatively until fusion vvas completed. Post operative tomogram vvas done at 6 months in ali pa-tients and tomogram or dynamogram vvas done at nine or tvvelve months in selected cases to evaiuate the status and the patterns of fusion

The donor bones vvere obtained from each patient's iliac bones and ribs of their ovvn.

The average of follovv-up period vvas 3.1 years (range one -12 years).

The overall fusion rate of noninfectious spinal diseases vvas 92% and that of infectious spinal diseases vvas 88% at one year after operation. Radiologically completed fusion vvas obtained 73.3%, incomplete fusion in 17.4%, and absorption of the grafted bone in 9.3% at one year after operation.

High fusion rate vvas obtained from spinal stenosis (90%) and contrary to this lovv fusion rate vvas in pyo-genic spondylitis (60%).

The fusing pattern of grafted bones could be categorized into five different types and the most common type among them vvas type I (61.0%).

İn clinical results, 79.4 percent of noninfectious group vvas satisfied and 76.9% in infectious group.

The most favorable clinical result vvas obtained in lumbar intervertebral disk herniation (86.8%) in noninfectious group and pyogenic spondylitis (80%) in infectious group.

İn conclusion, the fusion rate vvas higher in noninfectious spinal diseases than infectious spinal diseases, but the clinical results vvere not correlated vvith the status or pattern of the fusion.

Anterior interbody fusion is useful and recommendable method of surgery not only in.
