Metal-on-metal total hip arthroplasty with large heads may prevent early dislocation. The effect of the diameter of metal-on-metal bearings on systemic exposure to cobalt and chromium. Survivorship and Retrieval Analysis of Sikomet Metal-on-Metal Total Hip Replacements at a Mean of Seven Years. Metal-on-Metal Hip Resurfacing Arthroplasty M2 a Magnum: Large Metal Articulation Design RationaleĪrthroprosthetic cobaltism: neurological and cardiac manifestations in two patients with metal-on-metal arthroplasty: a case report. Comparison of Whole-Blood Metal Ion Levels Among Four Types of Large-Head, MoM THA Implants Pseudotumors in association with well-functioning metal-on-metal hip prostheses: a case-control study using three-dimensional computed tomography and magnetic resonance imaging. Sensitivity and specificity of blood cobalt and chromium metal ions for predicting failure of metal-on-metal hip replacement Metal-on-metal bearings total hip arthroplasty: the cobalt and chromium ions release concern How do serum cobalt and chromium levels change after metal-on-metal hip resurfacing? Blood and urine metal ion levels in young and active patients after Birmingham hip resurfacing arthroplasty: four-year results of a prospective longitudinal study. The effect of the diameter of metal-on-metal bearings on systemic exposure to cobalt and chromium Release of hexavalent chromium from corrosion of stainless steel and cobalt-chromium alloys highest safe level: 17 µg/L for chromium in blood and 20 µg/L for chromium in urine Levels rather than levels in plasma, serum, or red blood cells alone) note potential variation in the levels of chromium in plasma compared with those in serum (hence need to assess whole-blood normal chromium: mean serum chromium level of 0.28 µg/L (range, 0.06 to 0.93 µg/L) measurement, risk factors, and step-wise approach to treatment.
