This case study aimed at the effect of the plate system for anterior cervical spine surgery. There are numerous available plates, almost all of which are compact one-piece plates. Instrument-related complications might appear during the placement of relatively long plates in the treatment of multi-level cervical pathologies. 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 a multipartite structure for anterior cervical stabilization was intended. 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 limitations 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 course on either side as needed. The ease of application requires further verification via a cadaveric study.
