Stratofuse® Sponge is a 100% demineralized cancellous, compressible allograft sponge offered in multiple block and strip sizes. The clinician may hydrate it with BMA, PRP, blood, or saline, making it expandable, pliable, and trimmable. The Stratofuse® Sponge is both osteoconductive and osteoinductive; every lot is tested for osteoinductivity.
