Biomechanical Comparison of Different Vertebral Plate Designs for Anterior Cervical Discectomy and Fusion Using Nonlinear C3-T2 Multi-Level Spinal Models
Abstract. Anterior cervical discectomy and fusion is a common surgical procedure to treat spinal cord or nerve root compression. However, the clinical complications of anterior cervical plate system still occur. Past researchers have tried to improve the clinical complications by changing the screw thread or the screw orientation. The conclusion on the screw thread is quite consistent. Unfortunately, the studies on the screw orientation reached inconsistent conclusions. In addition, the effects of the screw orientation which are determined before the surgery are mainly based on the surgeon’s experiences without biomechanical evidences. Therefore, the purpose of this study was to investigate the clinical performances of anterior cervical plate for the anterior cervical discectomy and fusion.
