✓ In 200 cases following cervical diskectomy, cylindrical dowels of specially processed calf bone were placed in intervertebral holes, bored with a drill of the same size as the dowel. The anterior approach for cervical interbody fusion was used. With use of heterogenous bone, iliac osteotomy is unnecessary, and the hole is filled by a precisely formed, previously prepared, sterile dowel. The results are good, the operation time is shorter, and complications are diminished. The cases were evaluated separately from x-ray and clinical data.
