Event Description

This complaint is from a literature source.The following literature cite has been reviewed: campbell p, park sh, ebramzadeh e.Semi-quantitative histology confirms that the macrophage is the predominant cell type in metal-on-metal hip tissues.J orthop res.2022 feb;40(2):387-395.Doi: 10.1002/jor.25040.Epub 2021 apr 6.Pmid: 33749015; pmcid: pmc9292819.Objective and methods: numerous studies have examined the histology of metal-on-metal hip tissues for evidence of a dose response to metal wear but have often reported inconclusive or contradictory findings.The aim of the present study was to address these discrepancies using multiple histological scoring methods to characterize the tissue features of one large group of revised metal-on-metal total hips.Periprosthetic tissues from 165 asr xl metal-on-metal hip revisions (dor 2011 to 2017) were examined for features of aseptic lymphocytic vasculitis associated lesions (alval) as rated using two scoring systems as well as rankings for macrophage and lymphocyte numbers, intracellular wear debris and necrosis.This complaint will capture the generalized results of the pathological and histological studies of the explanted products and tissue samples as well as two patient specific results.Lot, model and catalog number are not available, but the suspected depuy device possibly associated with reported adverse events: depuy asr xl including a cup, femoral component femoral sleeve, and unk depuy femoral stem adverse event(s) and provided interventions associated with depuy devices: generalized results: all 165 patients were revised to treat alval, soft tissue necrosis, metal wear, elevated blood metal ions, and corrosion at the stem/head trunnion junction.The following were additional findings during the revisions: 86 pain, 62 elevated blood metal ions, 24 unspecified loosening, 19 metallosis, 14 pseudotumor (hypersensitivity), 6 osteolysis, 4 infection, 2 allergic reaction, tissue pathology results: 23 samples with identified tissue necrosis.
