Dynamic Test Methods for Running Shoes. On the one hand, dynamic loading on the hip endoprosthesis stem while walking with an iao that is already loosening is simulated in order to check the stem life expectancy. On the other hand, alternating loading is applied to the neck region of the prosthesis, which is clinically well-anchored.
ZwickRoell software allows you to run user-friendly progressive load tests Locati tests.
These tests can be implemented under physiological environmental conditions for example, temperature-conditioned saline solution with the use of the ZwickRoell temperature conditioning vessel. This enables you to perform a corrosion test to ASTM Fwhich tests a modular junction’s resistance to crevice corrosion and fretting corrosion under dynamic 7206–6. Determination of endurance properties of stemmed femoral components.
Testing of Hip Implants
A minimum of six hip endoprosthesis stems must withstand 5 million load cycles with a maximum load of N and a minimum load of N. Determination of endurance properties of head and neck region of stemmed femoral components. A minimum of six hip endoprosthesis stems must withstand 10 million load cycles at a load of 5. Endurance performance of stemmed femoral components with application of torsion. Artificial hip joints must withstand both compressive loads and torsion loads.
To determine the optimum materials and alloys, these are tested with a special testing machine. The artificial hip joint here made of metal is rotated on a support unit torsion loading and compression loading is applied at the same time.
Testing of Hip-Joint Endoprotheses – ASTM F, ISO
Testing of Hip Implants. The hip joint consists of the femur and the pelvis.
Diseases can make it necessary to replace parts of or the entire hip joint with an implant. Fatigue Tests on hip endoprotheses Torsion tests on artificial ball joints Testing of the anchoring of a hip endoprosthesis.
Use of the appropriate embedding device is the mechanical conditions specified in the standard, such as the orientation of 72066-6 hip joint prosthesis to the test load or the embedding height, together with the angle of load application, to be defined with accuracy.

Determination of endurance properties of stemmed femoral components A minimum of six hip endoprosthesis stems must withstand 5 million load cycles with a maximum load of N and a minimum load of N.
A precision-manufactured embedding device is used to embed the stem, ensuring exact orientation of the implant to the test loads. Head and foot flange assembly for simple and durable installation, taking into consideration the necessary degrees of freedom for the test.
Torsion Tests on Artificial Ball Joints Artificial hip joints must withstand both compressive loads and torsion loads. To determine the optimum materials and alloys, these are tested with a special testing machine, consisting of a kN ZwickRoell materials testing machine plus a Nm torsion drive. Testing of the Anchoring of a Hip Endoprosthesis Hip endoprostheses can be anchored in the femur with or without the use of bone cement.
In addition to fatigue tests on the prosthesis itself, the strength of the fastening in the bone must also be tested. For this, an endoprosthesis is anchored in natural or artificial bone, the load axis is adjusted by means of a clamping fixture and the entire test device is clamped in an AllroundLine Z testing machine.
During the cyclic loading, loads can be measured, together with any micro-movements between prosthesis and bone.
Customized implants — ZwickRoell delivers innovate testing technology to Karl Landsteiner University of Health Sciences Technology always greatly impacts medicine. This is due to demographic changes and the associated socioeconomic challenges to the health care system.
BS ISO 7206-6:2013
Innovations through customization in medical technology are necessary to maintain the current high standard. Musculoskeletal diseases such as osteoporosis or osteoarthritis are among the top five diseases in old age.
HC series servo-hydraulic testing machines Servo-hydraulic testing machines in the HC series are suitable for fatigue tests from 10 to 25 kN. LTM Electro-Dynamic Testing Machine Electro-dynamic testing machines are used to determine material and component fatigue strength in the areas of fatigue life and fatigue limit.
