1.1 This guide describes a laboratory method using a weight-loss technique for evaluating the wear properties of materials or devices, or both, which are being considered for use as bearing surfaces of human-hip-joint replacement prostheses. The hip prostheses are evaluated in a device intended to simulate the tribological conditions encountered in the human hip joint, for example, use of a fluid such as bovine serum, or equivalent pseudosynovial fluid shown to simulate similar wear mechanisms and debris generation as found in vivo<\/span> , and test frequencies of 1 Hz or less.<\/p>\n

1.2 Since the hip simulator method permits the use of actual implant designs, materials, and physiological load\/motion combinations, it can represent a more physiological simulation than basic wear-screening tests, such as pin-on-disk (see Practice F 732 ) or ring-on-disk (see ISO 6474).<\/p>\n

1.3 It is the intent of this guide to rank the combination of implant designs and materials with regard to material wear-rates, under simulated physiological conditions. It must be recognized, however, that there are many possible variations in the in vivo<\/span> conditions, a single laboratory simulation with a fixed set of parameters may not be universally representative.<\/p>\n

1.4 The reference materials for the comparative evaluation of candidate materials, new devices, or components, or a combination thereof, shall be the wear rate of extruded or compression-molded, ultra-high molecular weight (UHMW) polyethylene (see Specification F 648 ) bearing against standard counter faces [stainless steel (see Specification F 138 ); cobalt-chromium-molybdenum alloy (see Specification F 75 ); thermomechanically processed cobalt chrome (see Specification F 799 ); alumina ceramic (see Specification F 603 )], having typical prosthetic quality, surface finish, and geometry similar to those with established clinical history. These reference materials will be tested under the same wear conditions as the candidate materials.<\/p>\n
