The EVOL®SI Joint Fusion System improves osseointegration through the combination of high wettability and optimal surface chemistry (with optimized nano-roughness) that mediates bioactivity and specific protein absorption to the implant.  These properties regulate cell behavior and influence tissue regeneration by increasing the osteoblast functions, thus building more bone faster.

Compared to traditional coatings, where bone anchors to the coating, this HA Surface does not act as an interface separating bone from implant.  The nano-thin surface enables newly formed bone to grow directly into the micrometer topography, or roughness, of the implant surface, thus providing mechanical stability with no risk of cracking or delamination of the implant.
