•Materials used for helical blade are 316L stainless steel and titanium. •12.2mm Helical blade is used in PFN A2 nails (new gam nails) •10.5mm helical blade is used in humerus nails. The helical blade provides improved resistance to varus collapse and rotational control of the medial fracture segment compared to single screw fixation. •Use of the helical blade results in reduced bone removal versus use of a traditional hip screw. •These helical blade features are especially advantageous in osteoporotic fracture fixation. The innovative helical blade design was proven to provide superior resistance to migration and subsequent cut-out failure.
