A constant load of 756&nbsp;N (\u00b1 50&nbsp;N) is applied. According to Wirth et al. the translation, resulting in rim loading during abduction\/adduction is oriented at a 45\u00b0 angle from the long axis of the glenoid component. The amount of translation required to generate rim loading during abduction\/adduction depends on the radial mismatch between the glenoid component and the humeral component and will be adjusted individually. The wear test is conducted for 5 million cycles. The wear is determined gravimetically. &nbsp;<\/p>\n\n\n\n<p><em><sup><sub>[1] Michael A. Wirth, MD, Conrad Klotz, BS, MBa, Daren L.
