[On the stress state of bone cement fixing a hip joint prosthesis (author's transl)].
Using a simplified model, tests were made to investigate the shear stress distribution at a hip joint prosthesis. A marked increase of stress at the tip of the prosthesis was found through photoelasticity. This peak stress resulted in a safety factor of 3 against exceeding the shear strength of bone cement. Since the calculation of the stress is based on unfavourable assumptions, the actual factor of safety should show a higher value still.
