"Standard Test Methods for Sacroiliac Joint Fusion Devices\r\n\r\n\r\n\r\nDescribes static and fatigue testing of in-line and transverse sacroiliac joint (SIJ) fusion implants. In-line SIJ fusion implant test methods characterize the mechanical performance under shear and torsion by testing between simulated vertebral bodies, made of polyacetal blocks for dynamic loading, and stainless steel blocks for static loading. Transverse SIJ implant test methods evaluate the torsional strength, bending strength and pullout resistance of the implant inserted in Grade 20 polyurethane foam. Fatigue components are tested to 2.5 million cycles, or until failure."
