ASTM F 2028 : 2008 : R2012 : EDT 1

1.1These test methods measure how much a prosthetic glenoid component rocks or pivots following cyclic displacement of the humeral head to opposing glenoid rims (for example, superior-inferior or anterior-posterior). Performance is judged by the tensile displacement opposite each loaded rim after dynamic rocking.

1.2The same setup can be used to test the locking mechanism of modular glenoid components, for example, for disassociation.

1.3These test methods cover shoulder replacement designs with monolithic or modular glenoid components for cemented fixation.

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
