Product Name: Pfna Locking Screw Locking Blade Model NO.: locking blade Trademark: to-young Transport Package: PE Bag Specification: 80mm,85mm,90mm,95mm,100mm,105mm,110mm,115mm,120mm Origin: Jiangsu China HS Code: 902110000 Product Description Compaction of cancellous bone Inserting the PFNA blade compacts the cancellous bone providing additional anchoring, which is especially important in osteoporotic bone.Large surface and increasing core diameter guarantee maximum compaction and optimal hold in bone Increased stability caused by bone compaction around the PFNA blade has been biomechanically proven to retard rotation and varus collapse. Biomechanical tests have demonstrated that the PFNA blade had a significantly higher cut-out resistance in comparison with commonly-used screwsystems.
