Abstract
In thirty-six dissected hips from cadavera, six types of fixation of the prosthetic acetabular component to the acetabular tissue were devised, utilizing combinations of a variety of technical procedures: decorticating the cartilage, intruding the cup, reaming the bone, and perforating the residual bone tissue with anchoring holes (for cement). Mechanical tests showed that the greatest stability was achieved when the prosthetic cup was completely intruded, when all articular cartilage was removed and the socket was reamed, and when anchoring holes for cement were devised.
