Bone Cement Fatigue Test

ISO 16402 Similar to ASTM F2118, this test method describes a variety of tests for evaluating the static and fatigue strength of acrylic resin-based bone cement. Constant amplitude, uniaxial, and tension-compression tests are performed to generate an S-N curve using dumbbell-shaped samples.

Test

During the implantation process, bone cement is used to fill the space between the implant and the bone, and its long-term mechanical stability is crucial for the success of the implant. By conducting static and cyclic loading, the mechanical properties of these bone cements can be determined. 

ISO 16402 "Surgical implants - Acrylic resin cement - Bending fatigue testing of acrylic resin cement for orthopedics" provides guidelines for conducting bending tests on these cements in the laboratory. It includes a method of quasi-static bending testing and bending fatigue testing. 

A four point bending fixture is placed in a liquid bath filled with Ringer's solution and maintained at 37 ° C. After quasi-static bending testing, fatigue testing is performed to generate a stress level/cycle number (S/N) curve.
