Endoprosthetics
Endoprosthetics
A wide range of mechanical tests on endoprostheses can be performed with servo-pneumatically and servo-electrically operated universal testing machines from DYNA-MESS. DYNA-MESS has developed user-friendly special test rigs to fulfill special norms and standards for fatigue and wear tests.
We are DYNA-MESS. Test Systems.
Hip
ISO 7206-4
“Surgical implants – Tension torsion testing of artificial hip joints ISO 7206 Partial and total hip replacements – Part 4: Fatigue testing of prosthetic stems”
ISO 7206-6
“Surgical implants – Partial and total hip replacement – Part 6: Determination of the toughness properties of the caput and collum of the femoral stem”
ISO 7206-8
“Surgical implants – Partial and total hip replacement – Part 8: Loading capacity of prosthetic stems with torsional stress”
ISO 7206-10
“Surgical implants – Partial and total hip replacements – Part 10: Determination of resistance to static loading of modular prosthetic heads”
ISO 7206-12
“Surgical implants – Partial and total hip joint replacement – Part 12: Deformation testing of acetabular cups”
ISO 14242-1
“Surgical implants – Wear behaviour of total hip replacements – Part 1: Load and motion parameters for wear testing machines and associated test conditions”
Tests on hip endoprostheses are performed both as fatigue tests on the stems and as combined compression/torsion tests with ball cups. DYNA-MESS offers the DYNA-EndoWear machine especially for testing hip implants.
The DYNA-MESS testing software ensures compliance with the load values and – in the case of multi-axial loads – the correct temporal relationship between the individual loads.
Knee
ISO 14879-1
“Surgical implants – Total knee endoprostheses – Part 1: Determination of the loading behaviour of tibial pads for knee joint replacement”
ISO 14243-1
“Surgical implants – Wear behaviour of total knee endoprostheses – Part 1: Load and motion parameters for load-controlled wear testing machines and associated test conditions”
ISO 14243-3
“Surgical implants – Wear behaviour of total knee endoprostheses – Part 3: Load and displacement parameters for displacement-controlled wear testing machines and corresponding environmental conditions for testing”
DYNA-MESS has developed the DYNA-EndoK testing machine especially for testing knee implants in accordance with the ASTM 1223 / ASTM F2722 / ASTM 2723 / ASTM F2724 / ASTM F2777 standards.
Spine
ASTM F 1717-96
Endurance test on spinal fixators. Testing of a fully assembled spinal implant via two UHMWPE vertebral replacement bodies
ASTM F 1798-97
Testing of subcomponents of a spinal implant (fixation screws,…)
ASTM F 2077-01
Testing of intervertebral bodies
Dental
Testing of dental implants
DYNA-MESS offers a perfectly customised machine for testing dental implants in accordance with ISO 14801.
Accessories
Accessories for standardised testing
For standardised tests, both appropriate clamping devices and adapters for load application are available, which allow the prosthesis mounted at an angle to be loaded without transverse forces. In addition, corresponding basins with media preparation and various accessory holders are available to enable further tests (tensile tests, bending tests, etc.).
Bone cement
For the dynamic testing of bone cement, standardised test specimens are tested in bending tests.
Additionally, cemented implants (e.g. the stem of a hip joint in the os femoris) are dynamically loaded in order to investigate the bond between the implant and the bone.
