ANALYZING EXPERIMENTAL SYSTEM FOR HIP PROSTHESIS EXPOSED TO VIBRATION
This paper contains the description of a test system for a hip prosthetic through vibration analysis. Long-term success of the THR and TKR is affected by a high rate of erosion of the prosthesis, several years after surgery. One reason for this is the changing transfer of the load, which often cause bone erosion at the interface between the femur and artificial joint. Optimizing implant design and its mechanical behaviour can reduce this effect. Also testing the vibration frequency of the different parts of the bone and prosthesis it could be determined the frequency of unwanted vibration source.Key words: Hip prosthesis, vibration, accelerometer, THR, cement.
