Static and Dynamic Test Methods for Spinal Artificial Discs
Spinal artificial discs are tested under axial compression, compression-shear, and torsion to determine static and dynamic mechanical behaviour for device comparison. Dynamic testing is carried out for 10 million cycles, or until failure. Additional testing may be performed on artificial spine discs to address implant resistance to expulsion and implant wear resistance as per ISO 18192-1 and ISO 18192-2.
