Manufacturer Narrative

This follow-up report is being submitted to relay additional information.Visual examination of the provided pictures identified the explanted glenosphere and baseplate, both showing signs of wear and damage from extensive use.Device history record was reviewed and no discrepancies were found.It is alleged that the patient was a very active patient and the glenoid component was placed quite superiorly on the glenoid face with superior inclination, rather than inferiorly with inferior inclination.The effects of this were twofold.The superior position increased the risk of scapula notching, which would have explained the wear observed on the polyethelene where the poly had butted against the lateral border of the scapula.The superior inclination created a sheer force at the glenoid/implant interface rather than a compressive force, which would have predisposed the implant to micro-motion and compromised secondary fixation.Root cause was unable to be determined as the necessary information to adequately investigate the reported event was not provided.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
