Heart failure after conventional metal-on-metal hip replacements
Background and purpose - It is unclear whether metal particles and ions produced by mechanical wear and corrosion of hip prostheses with metal-on-metal (MoM) bearings have systemic adverse effects on health. We compared the risk of heart failure in patients with conventional MoM total hip arthroplasty (THA) and in those with metal-on-polyethylene (MoP) THA. Patients and methods - We conducted a...
متن کاملPerfusion MRI in hips with metal-on-metal and metal-on-polyethylene total hip arthroplasty: A pilot study.
OBJECTIVES Hips with metal-on-metal total hip arthroplasty (MoM THA) have a high rate of adverse local tissue reactions (ALTR), often associated with hypersensitivity reactions. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) measures tissue perfusion with the parameter Ktrans (volume transfer constant of contrast agent). Our purpose was 1) to evaluate the feasibility of DCE-MRI ...
متن کاملCeramic Surface Engineered Metal-on-Metal Hips system for Total Hip Arthroplasty and Resurfacing Hip Arthroplasty
components for the reconstruction of the acetabulum and metal femoral head components for conventional THA and RHA. The ACCIS®metal components are made of a chrome-cobalt-molybdenum alloy, but are different from other metal-on-metal prostheses. The surfaces of the metal components are engineered with the ceramic Titanium-Niobium-Nitride (TiNbN) in order to minimize metal particulate wear, to pr...
متن کاملCorrelation Between the Detailed Visual Inspection of Retrieved Metal-on- Metal Hips and Their Volumetric Wear
Introduction Metal-on-metal (MOM) total hip arthroplasty using large diameter femoral heads offer clinical advantages however the failure rates of these hips is unacceptably high. Retrieved hips have a wide range of wear rates of their bearing and taper surfaces and there is no agreement regarding the cause of failure. Detailed visual inspection is the first step in the forensic examination of ...
متن کاملThe Interchangeability of Plasma and Whole Blood Metal Ion Measurement in the Monitoring of Metal on Metal Hips
One hundred and twenty six paired samples of plasma and whole blood were measured with inductively coupled plasma mass spectrometry technique for metal ions analysis to determine a relationship between them. There was a significant difference between the mean plasma and whole blood concentrations of both cobalt (Co) and chromium (Cr) (p < 0.0001 for both Co and Cr). The mean ratio between plasm...
