方法：用317L不锈钢研制出颈椎前路钮扣钢板螺钉系统。
Methods: The anterior button-like buttressing plate fixation system was designed with 317L steel .
目的：比较带锁与非带锁颈椎前路钢板螺钉系统的即刻固定和抗疲劳强度。
Objective: To compare the fixation strength of locking and non locking anterior cervical plating initially and after fatigue.
目的：比较带锁与非带锁颈椎前路钢板螺钉系统的即刻固定强度和抗疲劳强度。
Objective: To compare the prompt fixation strength and antifatigue strength of the locking and non locking anterior cervical plating systems.
通常使用前路重建系统(前路颈椎钢板螺钉系统)稳定脊柱及轴向加压植骨块。
Usually, a ventral reconstruction system (anterior cervical plate screw system) is used for both further stabilization of the spine and axial compression on the fibula strut grafts.
结论：测试所用的可使用多轴固定螺钉的钢板系统，在生物力学方面是股骨髁上骨折的不错的选择。
Conclusions: The tested plate construct with its polyaxial locking screw mechanism provides a biomechanically sound fixation option for supracondylar femur fractures.
另外，系统提供每块钢板螺钉的确切放置位置及使用规则，这亦使手术更为标准。
In addition, there is a defined placement for each of the given plates and clear rules on how to use each, which are expected to lead to more standardized procedures.
