A FUTURE INSPIRED BY THE PAST

Arches date back all the way to the early Mediterranean civilizations (Mesopotamia, Greece, Persia and Ancient Italy.) Although arches were found in all of these civilizations, they were mostly reserved for underground architecture and drainage systems as a way to disperse the force from the earth above it. The Romans adopted the arch from the Etruscans of Tuscany, and were the first to use it more widely. The use of the Arch allowed the Romans to build longer roads, larger buildings, and stronger aqueducts. The arch is widely accepted as the grandfather of modern Architecture.

OPEN ARCH ARCHITECTURE

Spira®’s open architecture, arched design has large openings for significant graft packing. It decreases the risk of subsidence due to the design’s “snowshoe effect” and provides good visibility for fusion. Newly-forming bone grows onto and through the multiple roughened titanium arches to achieve maximum stability and complete endplate-to-endplate arthrodesis. The implant enables easy insertion with a smooth leading edge and pockets that interlock with the inserter to provide rotational stability. The arched design enables a distribution of load and stress throughout the cage, which is known from Wolff’s law to enhance fusion, and protects fusion zones from stress.

SURFACE BY DESIGN™

Our Surface by Design™ texture provides immediate stability with surface features designed for significant friction to help prevent motion. It encourages bone cell proliferation with roughened titanium surface, and promotes “mechanical fusion” bone ingrowth for short-term stability, using trabecular, bone-like surface design, with an average pore diameter of 500µm.
