Manufacturer Narrative

This follow-up report is being submitted to relay additional information.Reported event was confirmed by review of x-rays and medical records.Physical therapy notes imply that patient was aggressive with therapy and repeatedly reminded to follow post-op protocols.X-ray report findings include: generalized regions of lucency noted in the greater and lesser tubercles as well as likely in the glenoid.This is not sharply demarcated/periprosthetic but appears generalized in this region.May suggest stress shielding/bone resorption and can contribute to pain.Questionable joint bodies/synovitis.Also there is suspected calcific tendinitis, another cause of pain.Finally, widened ac joint can also be related to distal clavicle osteolysis which can be related to prior trauma and may be a source of pain if not chronic.Device history record (dhr) was reviewed and no discrepancies were found.Review of the complaint history determined that no further action(s) is/are required.Investigation results concluded that the reported event was due to patient non-compliance with post-operative physical therapy plan.A summary of the investigation has been sent to the complainant.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.
