Abstract

Experimental analysis of stress and strain on epoxy models of the human pelvis carried out by Sulzer Bros. Ltd. of Winterthur, Switzerland, in collaboration with the Orthopaedic Department of the University of Zürich, began three ago and has now shown that the subchondral bone within the acetabulum transmits a major part of the bearing load in the form of membrane stresses from the hip joint to the rim and then onto the cortical shell of the ilium and that the cancellous material within the pelvic bone is stressed to a much lower level in the natural physiological condition. The experimentally determined stresses could be extrapolated to show that in an individual of 60 kg weight, the membrane stresses in the subchondral bone attain values of ca. 98 kp/cm² whereas the peak normal compression stress within the cancellous material only reaches approx. 13 kp/cm².
