Manufacturer Narrative

The complaint product was not returned for analysis.The condition of humeral liner disassociation was not confirmed.The frequency of occurrence ranking is very low; therefore, this does not appear to be a design issue.The company is not aware of receiving any other complaint reports involving another part from these manufacturing lots of (b)(4) (adapter tray), (b)(4) (liner) and (b)(4) (glenosphere) pieces that have been in the field since 2014.A review of the device history record for the adapter tray and humeral liner showed that the named devices were accepted with conformance to the device requirements.Therefore, this does not appear to be manufacturing-related.The revision reported was likely the result of incomplete seating of the liner during implantation, forceful contact between the liner and glenoid bone (scapular notching), or extreme wear of the liner, which led to the liner detaching from the humeral adapter tray.However, these cannot be confirmed because the devices were not available for evaluation and adequate information was not provided.There is no patient medical information provided; therefore, it is not possible to assess the patient risk/clinical factors.In a review of the labeling and ifu 700-096-060 rev.M, device specific risks include: fracture, migration, loosening, subluxation, or dislocation of the prosthesis or any of its components, any of which may require a second surgical intervention or revision.It is also noted that excessive wear of the implant components secondary to impingement of components or damage of articular surfaces can cause early implant failure.Also, it is a known complication that a patient's age, weight, activity level, and/or trauma would cause the surgeon to expect early failure of the system.This device is used for treatment not diagnosis.No new information provided about the patient or event, asked not provided.
