Event Description

It was further reported that during the procedure, it was noted that a fungal infection was present.However, the surgeon noted that this was not a contributing reason for the revision procedure.

Manufacturer Narrative

(b)(4).Proposed g-code: mechanical (g04) - stem.The reported event is confirmed for incorrect placement/orientation per the original surgeon's confirmation and the mmi review.The reported event is not confirmed for infection.Radiographs were provided and identified the following: a reversetype right shoulder arthroplasty is present.The implant alignment and glenosphere position appear abnormal, especially on the oblique/lateral view, with suspected antero/inferior angulation of the glenosphere.The position and alignment would be best evaluated by ct or mri.Implant fit is maintained, however, there is malalignment as noted with apparent malposition of the glenosphere.Bone quality is mildly osteopenic.No signs of loosening, wear, radiolucency, or any other contributing factor that would cause issues with any of the components on the x-ray.No other concerns anatomically or with the implants that could contribute to the patient¿s pain and limited range of motion.Device history record was reviewed and no discrepancies relevant to the reported event were found.The root cause of the reported issue is attributed to use error, surgeon mispositioning implants.Infection: the root cause of the reported event was determined to be unrelated to the implanted zimmer biomet devices; therefore, a review of the device history records will not be performed.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.
