The EndoLab^® hip joint simulator performs 2x3 simultaneous tests (plus 2 soak controls). The specimens are oriented in an anatomically correct position, the resulting hip joint force is applied via the cup. Consequently, the direction of the force vector is constant relative to the cup and moves relative to the head. All three in-vivo angular displacements are simulated: Flexion/extension, abduction/adduction and internal/external rotation. Please watch our short video on YouTube to see the simulator moving. The specimens are assembled under laminar flow conditions and sealed by capsulated single test chambers to exclude contamination. The temperature of the test fluid as well as the fluid level are controlled throughout testing. The wear of the components is determined gravimetrically. Following customer request an analysis of the wear debris according to ISO 17853 can be conducted.
