Event Description
|
It was reported a patient underwent shoulder revision approximately eight years post-implantation due to pain, dysfunction, aseptic loosening, elevated metal ion levels, and adverse local tissue reaction.During the revision, the glenosphere and baseplate were found to be loose.Extensive wear on trunnion was noted, which is suspected to be the source of the metallosis and metal ion elevation.All components were revised.
