Deformation of Acetabular Shells

Test method for evaluating the magnitude of deflection of an acetabular cup when loaded across the open face. A test frame can be used to apply a constant load to opposite edges of the cup while a coordinate measuring machine simultaneously measures the cup deflection compared to the unloaded state. The degree of cup deflection may affect the tribological properties of the THR system, particularly for hard-on-hard bearings.
