[Secondary stability of cemented and non-cemented acetabular implants ex-vivo under dynamic load].

Objective: To measure the bone-prosthetic implant interface micromovement during the application of physiological load by using a material testing system (MTS).

Methods: The cadaveric hip specimens were used to simulate a single leg stance and the joint in the neutral position. Micromovement was recorded via a 3-dimensional transducer in the acetabula of postmortem specimens, which had been preserved in formalin.
