Manufacturer Narrative

(b)(4).This follow-up report is being submitted to relay additional information.Multiple mdr reports were filed for this event, please see associated reports: 0001825034-2022-02706-1 and 0001825034-2022-02705-1.H6: component codes: mechanical (g04) - head.Visual examination of the provided pictures identified for the bio-mod offset was verified to complaint information.No noticeable damage can be seen.Review of the device history record(s) identified no deviations or anomalies during manufacturing related to the reported event.Medical records/radiographs were provided and reviewed by a health care professional.Review of the available records identified the following assessment of imaging: a right shoulder arthroplasty is present.There is marked superior position of the humeral implant in relation to the glenoid implant consistent with a severe rotator cuff tear.Lucency along the glenoid implant fixation is consistent with implant loosening.There is no evidence of humeral implant loosening.The glenoid appears loose as noted, radiolucency is present.There is malalignment with superior position of the humeral implant in relation to the glenoid.Bone quality is osteopenic.The loosening and rotator cuff tear with migration would lead to revision to a reverse type system.A definitive root cause cannot be determined.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.
