Orthopaedic joint prostheses. Guide to laboratory evaluation of change of form of bearing surfaces of hip joint prostheses | Status: Current

1 Scope This Technical Report gives guidance on the methods available for the measurement of change of form (wear, creep, plastic deformation, etc.) of the bearing surfaces of hip joint prostheses when tested in hip joint simulators. It highlights the strengths and weaknesses of the methods in an attempt to unify experimental technique and to increase the accuracy, precision and comparability of "wear test" data.

NOTE Attention is drawn to ISO/TR 9325 regarding hip joint simulators.
