BioMechanics

ApiFix has conducted thorough fatigue and bio-mechanics tests

 

Fatigue Test per ASTM F 1717

  • Test performed by EndoLab GmbH (Germany)
  • ApiFix Run-out load at 5,000,000 cycles was 1000N
  • Standard fusion systems of good quality holds around 300N*

Poly-Axial Screws Design

  • Enables flexibility in screw insertion trajectory
  • Maintains spine flexibility
  • Enables correction over time
  • Prevents transfer of any movement between the screw and the implant
  • Protects the screw-bone interface
  • Unique ceramic coating of the joint maximizes bearing performance and minimizes wear
