This complaint is from a literature source.The following literature cite has been reviewed: ahmed ss, bawale r, jain s, samsani s.Metal ion levels comparison: metal-on-metal hip resurfacing vs total hip arthroplasty in patients requiring revision surgery.J orthop.2018 sep 28;15(4):1013-1016.Doi: 10.1016/j.Jor.2018.09.002.Pmid: 30319224; pmcid: pmc6180337.Objective and methods: the purpose of this study was to compare the reasons for revision of 104 patients who received either a mom tha (54) or mom hra (50) between 2009 and 2014.All thas were a depuy pinnacle/corail metal on metal hip.The resurfacing group received either a depuy asr or a construct manufactured by a competitor.To be included, all the patients were revised to treat symptomatic mom disease including pain, elevated blood metal ions, pseudotumor, metallosis, and evidence of armd.The meal level of serum cobalt was 24 ppb and 28.23 ppb in the tha and hra respectively.The meal serum levels of chromium were 13.24 ppb and 19.67 ppb in the tha and hra respectively.All 104 constructs were revised.As there is insufficient information to determine how many depuy asr hras were revised, the quantity will be captured as 1.The depuy pinnacle cup will be excluded as it is reasonable to attribute the results to known complications of metal-on-metal articulating surfaces and stem/head trunnion micromotion.Lot, model and catalog number are not available, but the suspected depuy device possibly associated with reported adverse events: depuy asr including a cup and femoral component.Pinnacle metal liner, unk metal femoral head, and corail femoral stem.Adverse event(s) and provided interventions associated with depuy devices: 54 revisions of the pinnacle liner, unk femoral head, and corail stem to treat pain, pseudotumor, armd, metallosis, and elevated blood metal ions.Unknown number of depuy asr revisions to treat pain, pseudotumor, armd, metallosis, and elevated blood metal ions.
