Our follow-up study of 175 cases of interbody fusion of the lower cervical spine was conducted to show the complications that occurred in our department with what is considered to be a tried and tested method. From 1976 to 1990, 175 patients were treated with this method. These 175 cases included 150 fractures and/or dislocations. The indications for surgery in the remaining 25 cases were tumors and metastases, inflammatory or degenerative diseases and chronic instabilities following laminectomy. The following complications were seen: 4 cases of infection, 3 postoperative redislocations, 2 cases of extensive loosening of metal, 1 unilateral lesion of the vertebral artery, 1 nonunion with plate fracture, 1 post-operative radicular disorder in an otherwise neurologically normal patients, and 1 secondary extension of the interbody fusion required after failure to recognize a two-segment lesion.
