The risk of early complications is high after monoblock acetabular metal-on-metal (MoM) THA revisions. However, there is a paucity of evidence regarding clinical complications after isolated head-liner exchange of modular MoM THA.

Adverse reactions to metal debris after total hip arthroplasty are an increasing concern. Metal debris is released from the metal-on-metal articulation itself as well as from the head-neck taper. Ther...
Electrocatalytic water splitting into H2 and O2 is a key technology for carbon-neutral energy. Here, we report a modular materials design leading to noble metal-free composite electrocatalysts, which ...
The purpose of this study was to compare the all-polyethylene tibial component with the modular metal-backed component in primary total knee arthroplasty. A retrospective review of 1064 patients recor...
Prior to being largely abandoned due to unacceptably high failure rates and the adverse physiologic reactions to metal ions, metal-on-metal (MoM) total hip arthroplasty (THA) and hip resurfacing (HR) ...
A single-center study of 144 THAs revised specifically for periprosthetic joint infection (PJI) observed that trabecular metal (TM) acetabular components had a reduced risk of rerevision for subsequen...
This is a multi-center, randomized study to compare blood and urine cobalt, chromium, and titanium ion levels of a metal-on-metal articular bearing coupled with two different head sizes to...
The aim of this study is to demonstrate the non-inferiority of the ceramic-on-metal articulation using large diameter bearings (38mm to 60mm) compared to the metal on metal articulation us...
Slightly elevated blood metal levels have been found in adults undergoing hip and knee replacement. It is unknown whether pediatric patients with metal implant(plates/screws/rods) have ele...
A clinical Evaluation to determine metal ion release from 4th generation metal-on-metal hip articulating surfaces in cementless total hip arthroplasty.
This is a pilot study to compare systemic concentrations of cobalt and chromium in patients that have previously undergone total hip arthroplasties with ceramic on metal and metal on metal...
Neutral or negatively charged ligands bonded to metal cations or neutral atoms. The number of ligand atoms to which the metal center is directly bonded is the metal cation's coordination number, and this number is always greater than the regular valence or oxidation number of the metal. A coordination complex can be negative, neutral, or positively charged.
Proteases which use a metal, normally ZINC, in the catalytic mechanism. This group of enzymes is inactivated by metal CHELATORS.
Supramolecular networks that consist of ordered arrangements of organic electron donor linkers (usually ditopic or polytopic organic carboxylates) and metal cations. They can have an extremely high surface area and adjustable pore size that allows for the insertion of other molecules capable of various functions such as catalysis, capture of carbon dioxide, and drug delivery.
The technique of washing tissue specimens with a concentrated solution of a heavy metal salt and letting it dry. The specimen will be covered with a very thin layer of the metal salt, being excluded in areas where an adsorbed macromolecule is present. The macromolecules allow electrons from the beam of an electron microscope to pass much more readily than the heavy metal; thus, a reversed or negative image of the molecule is created.
A family of soluble metal binding proteins that are involved in the intracellular transport of specific metal ions and their transfer to the appropriate metalloprotein precursor.
