The literature article entitled, "histopathological characterization of corrosion product associated adverse local tissue reaction in hip implants: a study of 285 cases" written by benjamin f.Ricciardi, allina a.Nocon, seth a.Jerabek, gabrielle wilner, elianna kaplowitz, steven r.Goldring, p.Edward purdue and giorgio perino published by bmc clinical pathology ricciardi et al.Bmc clinical pathology (2016) 16:3 doi 10.1186/s12907-016-0025-9 was reviewed.The article's purpose: "the purpose of this study was to describe the histological patterns observed in the periprosthetic tissue of failed tha in three different implant classes due to altr and their association with clinical features of implant failure." depuy products utilized: asr resurfacing, asr xl, pinnacle ultramet, mom bearing srom - all retrieved as failures due to altr - all bearing surfaces mom.Adverse events: soft tissue necrosis, metallic and black particles (debris contributed to wear and corrosion), device corrosion, osteolysis (contributed to foreign body debris), hypersensitivity (noted by increased macrophages, lymphocytes, eosinophils), elevated blood ion levels ranging 0-169 co and 0-64 cr.As the article does not specify which product platforms are associated with specific adverse events, platforms are grouped and captured as 1 impacted product for each product type.The article does not provided adequate information to determine accurate quantities.
