Event Description
|
It was reported that during a check-up appointment, the patient reported increasing pain for a long time of the groin area and left buttock, on a follow-up x-ray of the left hip joint (after implantation of the 2007 recap) showed features of bone atrophy in the area of the hip endoprosthesis, probably due to alval.The patient probably developed alval (aseptic lymphocyte-dominant vasculitis-associated lesion) caused by the toxic effects of elevated serum levels of heavy metal ions (cobalt, chromium, nickel) that are products of friction of the metal surfaces of the endoprosthesis.There is no additional information available at the time of this report.
