[Mechanical properties of bonding between cancellous bone and polymethylmetacrylate. IV. Tensile fatigue strength (author's transl)].

In joint replacement the fixation of implants to bone is loaded dynamically. The fatique strength of the bonding of PMMA to cancellous bone was determined for cyclic tensile loading. It was found to be 35% of the static tensile strength and greater than 0.6 Nmm-2 within a 95%-safety-range.
