文献摘要 BACKGROUND

有许多可用的板,其中几乎所有是紧凑的一体式板。在放置相对较长的钢板治疗多层次颈椎病时,可能会出现器械相关的并发症。为了克服这一潜在的问题,设计了一种新型的铰接板系统。我们的目的是描述有限元分析和力学评估。

MATERIAL AND METHODS

设计了一种新型的颈椎前路稳定钢板系统。节段钢板设计用于椎体腹侧表面。板的长度从9到13毫米不等。一端有杆子,另一端有钩子。终端点由一端的钩或杆组成,但另一端是盲的。在施加弯曲、轴向荷载和拉伸力的情况下,对结构进行了有限元和力学试验。

RESULTS

有限元和机械试验结果得出了系统功能失效和破坏的临界值。

CONCLUSIONS

铰接系统被证明是机械安全的,它可以根据需要在两侧扩展系统。易用性需要通过尸体研究进一步验证。


BACKGROUND

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.

MATERIAL AND METHODS

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.

RESULTS

Finite element and mechanical testing results yielded the cut off values for functional failure and breakage of the system.

CONCLUSIONS

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.
