The Tribology of the Total Hip Replacement

  • M. Ungethüm
Conference paper


In view of the stresses arising in a hip replacement, a material for a sliding surface bearing used in such an implant should have the following mechanical properties: High wear resistance under conditions of sliding friction in order to ensure a sufficiently long life. Low coefficient of friction to minimize the motive forces required; Sufficiently high compressive strength to avoid cold flow and pitting; A modulus of elasticity which is substantially as low as that of bones so that shocks can be effectively absorbed and low stresses are involved in a transmission of socket deformations.
