INFLUENCE OF INADEQUATE CEMENTING TECHNIQ UES ON MECHANICAL LOADING OF BONE-CEMENT

Good, painfree and durable function of an endoprosthesis is highly dep endent on its anchorage in the bony bed. Apart from the problem of mec hanical loading of the prosthesis and the change in the strains in the cortical bone, stresses on the bone cement as a force-transmitting el ement, are of considerable importance. Inadequate cementing technique and resulting faulty cementing is a common cause of loosening of the e ndoprosthesis. The present article investigates the influence of inade quate cementing technique on the stress and strain conditions of bone cement, in particular at the distal end of the prosthesis.
