Equipment Failure Analysis
Impingement of the glenoid with bone at the edge of the humeral component and edge deformation secondary to eccentric forces of the humeral head on the glenoid rim are highly associated with glenoid loosening. Analysis of retrieved glenoid components, along with patient, design, and surgical factors, provide important information on the causes of component failure.
