There are numerous available plates, almost all of which are compact one-piece plates. During the placement of relatively long plates in the treatment of multi-level cervical pathologies, instrument related complications might appear. In order to overcome this potential problem, a novel 'articulated plate system' is designed. We aimed to delineate finite element analysis and mechanical evaluations.
A new plate system consisting of multi partite structure for anterior cervical stabilization was designed. Segmental plates were designed for application onto the ventral surface of the vertebral body. Plates differed from 9 to13 mm in length. There are rods at one end and hooks at the other end. Terminal points consisted of either hooks or rods at one end but the other ends are blind. Finite element and mechanical tests of the construct were performed applying bending, axial loading, and distraction forces.
Finite element and mechanical testing results yielded the cut off values for functional failure and breakage of the system.
The articulated system proved to be mechanically safe and it lets extension of the system on either side as needed. Ease of application needs further verification via a cadaveric study.
现有多种钢板，几乎都是一体式紧凑型钢板。在治疗多节段颈椎病变放置相对较长的钢板时，可能会出现与器械相关的并发症。为克服这一潜在问题，设计了一种新型“铰接式钢板系统”。我们旨在阐述有限元分析和力学评估。
设计了一种用于颈椎前路稳定的新型多部件结构钢板系统。节段性钢板设计用于椎体腹侧表面。钢板长度从9毫米到13毫米不等。一端有杆，另一端有钩。末端一端为钩或杆，但另一端为盲端。对该结构进行有限元和力学测试，施加弯曲、轴向加载和牵张力。
有限元和力学测试结果得出了系统功能失效和断裂的临界值。
铰接式系统经证明力学上是安全的，并且可以根据需要在两侧延长系统。其应用的简便性需要通过尸体研究进一步验证。
