Hip Femoral Fatigue Fixture The hip femoral fatigue fixture was specifically designed to meet the enhanced requirements of ISO 7206-4. The fixture simulates the fatigue loading of a hip stem during a gait cycle. The easy-to-install fixture consists of a specimen potting holder, saline chamber and seals, a low friction loading head incorporating a low friction bearing and lower adapter for mounting to the system load cell. The assembly comes complete with a temperature controller and a recirculating pump for complete in vivo testing. The flexible specimen holder allows a wide variety of hip geometries, offset angles, embedding materials and embedding depths to be used. Application Range • Type of loading: cyclic compression, bending, torsion • Accommodates both metallic and non-metallic based hip prostheses, suitable for a wide variety of geometries • Deep specimen holder allows a variety of offset angles and embedding depths • Special low friction loading head to minimize off-axis loads • Corrosion-resistant construction to allow a variety of embedding mediums to be used • High stiffness fixturing to allow loading frequencies up to 30 Hz for a reduction in test time and costs • Saline bath to assist in simulation of in vivo conditions • Combined temperature/ aeration control to ensure environmental conditions are maintained • Specimen material: metallic and non-metallic hip prostheses • Specimen shapes: prostheses with a plane of symmet Principle of Operation The specimen is embedded into the specimen holder while maintaining the required offset angles and embedding depth. The specimen holder is then mounted to the machine and the saline chamber fixed in position. The test specimen is then immersed in the fluid test medium and the loading head introduced. Through compression loading via the loading head, the specimen is subjected to loads and frequencies as specified in ISO 7206-8. The test ends either when specimen fails or a specified number of cycles have been attained. Accessories for Materials Testing • Applies compression, bending and torsional stresses to meet requ
