TOSCA®  Standard and Expansion – Anterior Cervical Stabilization

Promotional feature

In 2005, the first SIGNUS plate for anterior cervical stabilization was launched: TOSCA. It offers the user a high degree of flexibility for ventral stabilisation of C2 to C7. Now, there are two designs available – and at 1,6mm both are among the thinnest plates on the market. With the very thin plate design and the semi-rigid screw connection TOSCA Standard and TOSCA Expansion allow for optimal load transmission onto the bone (Wolff’s law), thereby supporting segment fusion. Both systems come with a wide range of pre-lordosed plates for one to four segment constructs. The implants are manufactured from a biocompatible titanium alloy (Ti-6AI-4V) with proven strength.

Due to a large selection of self-tapping screws, TOSCA Standard can be used either mono- or bicortically. Colour coding makes size identification easy.
TOSCA Expansion stands for optimized stability – even with poor bone quality. The variable- and fixed-angle expansion screws are anchored in the bone in the same way as a dowel.

Choose a system suitable for your surgical technique.
