英文摘要:
      Objective: To study the biomechanical feature of a newly designed cervical vertebra internal fixation device and its clinical applications Methods: Some functional spinal units were fixed respectively with titanium plate, fusion cage and new device designed by ourselves, then a controlled biomechanical study including flexion, extension, torsion and lateral bending was performed and the results were analyzed. Results: As to the mechanical performance, fusion cage showed poor performance in extension test and so did the titanium plate in the distortion test. However, the new device showed good performance in every test. Conclusion: Both simple titanium plate fixation and simple fusion cage fixation have biomechanical defaults, but they are complementary. The titanium plate-interbody fusion cage avoids the defaults and has specific advantages.
