Anterior Cervical Fusion and Interbody Stabilization with the Trapezial Osteosynthetic Plate

Since March 1980, the trapezial osteosynthetic plate was used in 13 anterior cervical interbody fusions for rigid fixation. There were 8 spondylotic myelopathies, 2 cervical herniations and 3 ossifications of posterior longitudinal ligament, which involved 2 pseudarthrosis after anterior cervical interbody fusion. Follow-up averaged 10.5 months.The results were as follows.1. A postoperative recumbency was within 7 days in all cases.2. In all cases, a solid fusion was achieved.3. Loosening of the fixation screws was seen in 3 cases, 3 screws, which were all inserted in interbody of anterior cervical fusions. No loosening of the fixation screw was seen, which was inserted in vertebral bodies.
