"literature article entitled, ¿the relationship between the presence of metallosis and massive infection in metal-on-metal hip replacements¿ by james r.Donaldson, et al, published by hip international (2010), vol.20, no.02, pp.242-247, was reviewed.The authors present a small series of a previously unreported complication, which appears specific to metal-on-metal bearing surface arthroplasties: three cases of infection in the presence of local metal debris and histological features of aseptic lymphocytic vasculitis associated lesions (alval).Each case is associated with significant soft tissue loss and bone destruction to such an extent that pelvic discontinuity has occurred.Two of the cases presented were implanted with competitor products and are not included in this complaint.Case 2, with an asr-xl system and corail stem is captured in this complaint." (b)(6) male with asl-xr implant and corail stem.Implanted may 2006.Excision arthroplasty for mrsa infection, worsening pain, and suspected loosening of acetabular component.Intraoperative confirmation of pseudotumor, heterotopic ossification, soft tissue necrosis, acetabular osteolysis with pelvic discontinuity and cup loosening, black metal stained periarticular fluid, pelvic and femoral osteolysis.Patient was not revised as of this writing because his inflammatory and infection markers were still too elevated.Excision performed in june 2008 with positive histological identification of mrsa in the joint.
