Factors affecting the mechanical stability of the cemented acetabular component in total hip replacement
RG Volz and RJ Wilson
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.
