News: New cervical plate system with screw locking mechanism: Reliability and flexibility for anterior fusion ASCOT® – Maximum stability and minimum stiffness in cervical interventions

Alzenau, June 18, 2015. SIGNUS (Alzenau) is expanding its product range for the cervical spine. Along with TOSCA® and TOSCA® II Standard, ASCOT is a new system that is now available for anterior stabilization in interbody fusion. Due to its integrated screw locking mechanism and its flat, semi-rigid plate design, ASCOT offers reliability and flexibility in the operating room.

Cervical plate systems must adapt to the biomechanical processes in the cervical spine in the best possible way, to enable optimum fusion results. This is why the cervical plates developed by SIGNUS have a flat and semi-rigid design, which promotes optimum load transfer to the bone and prevents the stress-shielding effect, thus favouring the physiological stimulation of the bone (Wolff's law) – whilst simultaneously preventing tissue irritations. The positive influence of this plate design on fusion has already been proven in studies, in comparison with inferior outcomes with rigid systems1,2,3.

Due to the high degree of angle variability of the screws (10° in every direction), implantation is greatly facilitated, as the plate can thus adapt to the patient anatomy. ASCOT also offers a crucial advantage: An expansion ring integrated in the plate hole is activated when the screw is screwed in and effectively prevents the postoperative back-out. An additional surgical step is therefore unnecessary and the activated locking mechanism can be easily checked by the surgeon by way of visual inspection. "ASCOT is the result of our many years of experience and continuous advancement in the area of cervical solutions. It combines a proven, fusion-supporting design with a reliable locking mechanism, which efficiently prevents screw migration and is very easy and safe to use," says SIGNUS Managing Director, Uwe Siedler.

Due to a large selection of mono- and polysegmental plates, ASCOT adapts perfectly to the respective patient anatomy. The plate's narrow profile and generous fenestration give the surgeon an unimpeded view of the intervertebral space during surgery, thus providing additional safety.

ASCOT is implanted via an anterior approach to temporarily stabilize the cervical spine (C2 to C7), until such time as solid bony fusion has occurred. The implant can fixate up to four segments and is used for instabilities caused, for example, by degenerative disc diseases, spinal canal stenosis, spondylolisthesis, trauma or failed fusions.
