Neuropsychiatric symptoms following metal-on-metal implant failure with cobalt and chromium toxicity
BACKGROUND There were at least 31,171 metal-on-metal (MoM) hip implants in the UK between 2003 and 2011. Some of these were subject to failure and widescale recalls and revisions followed. METHOD This is a presentation of ten cases (mean age 60 years) where we evaluated neuropsychiatric morbidity following metal-on-metal hip implant failure and revision. Implants were ASR total hip replacemen...
متن کاملSensitivity and specificity of blood cobalt and chromium metal ions for predicting failure of metal-on-metal hip replacement.
Blood metal ions have been widely used to investigate metal-on-metal hip replacements, but their ability to discriminate between well-functioning and failed hips is not known. The Medicines and Healthcare products Regulatory Agency (MHRA) has suggested a cut-off level of 7 parts per billion (ppb). We performed a pair-matched, case-control study to investigate the sensitivity and specificity of ...
متن کاملCobalt and chromium measurement in patients with metal hip prostheses.
Approximately 1 million metal-on-metal (MoM) hip prostheses have been implanted worldwide to alleviate pain, restore hip function, and improve overall quality of life. These implants contain femoral and acetabular bearing surfaces that are typically composed predominantly of cobalt (Co) and chromium (Cr). Although the majority of MoM hip replacements have been successful, multiple recent report...
متن کاملChromium and cobalt ion concentrations in blood and serum following various types of metal-on-metal hip arthroplasties
BACKGROUND AND PURPOSE Widely different metal ion concentrations in blood and serum have been reported with metal-on-metal (MoM) implants. We reviewed the literature on blood and serum ion concentrations of chromium (Cr) and cobalt (Co) following various MoM hip arthroplasties. METHODS Studies were searched for in the Medline database, Embase, and the Cochrane Database of Systematic Reviews. ...
متن کاملChromium and cobalt ion release following the Durom high carbon content, forged metal-on-metal surface replacement of the hip.
We evaluated the concentrations of chromium and cobalt ions in blood after metal-on-metal surface replacement arthroplasty using a wrought-forged, high carbon content chromium-cobalt alloy implant in 64 patients. At one year, mean whole blood ion levels were 1.61 microg/L (0.4 to 5.5) for chromium and 0.67 microg/L (0.23 to 2.09) for cobalt. The pre-operative ion levels, component size, female ...
