OSferion Bone Void Filling

OSferion is an osteoconductive bone graft substitute and bone void filler consisting of 100% beta-tricalcium phosphate (β-TCP). OSferion’s micro- and macroporous structure allows it to be resorbed and replaced by bone during the healing process. OSferion wedges are intended to be used in conjunction with the distal femoral and high tibial opening wedge osteotomy plates and screws to promote healing and provide added rigidity to the repair. The chamfered wedge design of the OSferion implants corresponds to the shape of the osteotomy and can be easily trimmed to size using a rongeur.
