As a result of research conducted in the Metal Forming Institute in Poznan, SBT-03 simulator for friction and wear testing of human intervertebral disc endoprostheses was modernized. The structure of the device allows reflecting of the range of mobility and loads present in the natural spine. Moreover, the device allows recording and measurement of such parameters as axial compression force, moment of friction, temperature in the friction loop and number of operation cycles. This enables an evaluation of the intensity of wear processes of different designs of structures of a lumbar spine intervertebral disc endoprostheses depending on the type of materials used and production method.
