Vitrium’s combination of the mechanism of action of bioactive glass, structural capabilities, intraoperative modification and unique, engineered porous structure offer the properties of an ideal orthobiomaterial, offering performance advantages over bone grafts, substitutes and inert materials currently available such as allograft, TCP and spacers made from PEEK and porous titanium
Radiographic results from two initial patients of Vitrium wedges implanted in procedures of the extremities can be seen in the images below
The images below are from a patient simultaneously receiving a Vitrium wedge in a Cotton (cuneiform) osteotomy and a wedge constructed from corticocancellous allograft in an Evans (calcaneal) osteotomy. At 16 weeks postop the Vitrium wedge is nearly fully resorbed and replaced by remodeled bone. When utilizing allograft in the Evans osteotomies, surgeons often report that surrounding bone will grow into apposition and “tack weld” to the graft without incorporating. Because of this, when under load, the allograft may be pulled apart.
Based on initial clinical experience, surgeons report that Vitrium maintains anatomical correction, is easy to customize and implant, and is reliably replaced by host bone, making it an ideal material for applications where structural bone graft is required.
