Cutting TechnologyThe Apex ® Pin <strong>Fixation</strong> System uses an advanced cylindricalthread profile that is designed to improve anchorage andpull-out resistance.Apex One Step Pins have a tip design, that providesoptimal cutting conditions during the drilling phase.A U-shaped thread increases contact with the bone byover 30% and optimises the stress distribution in thebone by reducing radial cortical tension.A unique double helical flute creates homogenous threadprofiles and evacuates bone chips to the rear.These design features have significantly reduced insertiontime and temperature, and have improved anchorageconditions. The axial force and the torquerequired to insert the pins have also been significantlyreduced. †U-shapedthreadSelf-tappingsectionSelf-drilling tip4
Advanced Cutting TipDesigned to:Act as a drill bit and a screw simultaneously.Allow an accurate drilling of the second cortex.Minimise cortical protrusion due to a shorter tip pointwhich reduces soft tissue damage.Reduce insertion moments due to improved cuttingparameters.Reduce insertion temperature tobelow 50°C.Reduce operative time due totheir one step procedure.Improve the cutting of the threaddue to a better evacuation ofbone chips through a uniquedouble helical flute.Reduce risk of cortical damagedue to uniform stressdistribution.50°CAdvanced Thread ProfilePositive cutting angleimproves cortical contactDesigned to:Provide improved anchorageImprove frame stabilityReduce risk of infectionImprove fatigue and pull out resistance5
