ISO 7206-4, 7206-6, and 7206-8 Endurance and Fatigue Testing Artifical Hip Implant Prostheses
Subscribe to Instron News! Software for Series Systems.
Fatigue testing of hip implants is used to determine the endurance properties by simulating the dynamic loading of the implant during gait. During the cyclic loading, loads can be measured, together with any micro-movements between prosthesis and bone. HC series servo-hydraulic testing machines Servo-hydraulic testing machines in the HC series are suitable for fatigue tests from 10 to 25 kN.
Diseases can make it necessary to replace parts of or the entire hip joint with an implant.

Next Checking to see if you are a returning visitor…. Description Literature Contact Us Following surgery, proximal loosening and stress shielding can occur as a result of normal activity and can iao to abnormal loading profiles.
The fixture can also be easily adapted to suit other testing machines and test setups. Endurance properties testing and performance requirements of neck region of stemmed femoral components Status: Following surgery, proximal loosening and stress shielding can occur as a result of normal activity and can lead 7206- abnormal loading profiles.
A precision-manufactured embedding device is used to embed the stem, ensuring exact orientation of the implant to the test loads.
On the one hand, dynamic loading on the hip endoprosthesis stem while walking with an implant that is already loosening is simulated in order to check the stem life expectancy. Musculoskeletal diseases such as osteoporosis or osteoarthritis are among the top five diseases in old age. The ElectroPulsTM E Linear-Torsion is a state-of-the-art, all-electric test instrument designed for dynamic and static testing on a wide range of materials and components.
Head and foot flange assembly for simple and durable installation, taking into consideration the necessary degrees of freedom for the test. The fixture simulates the fatigue loading of a hip stem during a gait cycle. A minimum of six hip endoprosthesis stems must withstand 5 million load cycles with a maximum load of N and a minimum load 726-6 N.
Use of the appropriate embedding device enables the mechanical conditions specified in the standard, such as the orientation of the hip joint prosthesis to the test load or the embedding height, together with the angle of load application, to be defined with accuracy.
