Product Overview
Provides immediate stability with surface features designed for significant friction to help prevent motion
Encourages bone cell proliferation with roughened titanium surface 1,2
Promotes “mechanical fusion” bone ingrowth for short-term stability, using trabecular, bone-like surface design, with an average pore diameter of 500µm
OPEN ARCHITECTURE
ARCHED DESIGN
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.
