Researchers reviewed the MRI images of 70 patients who ultimately underwent revision surgery for a failed MoM implant. The images were assessed for the presence of tissue damage, swelling and other characteristics.
The study found that an MRI is highly sensitive and specific to identifying tissue damage in MoM total hip replacement (THR) patients. Early identification of at-risk patients can result in timely revision surgery, when necessary, decreasing pain and future damage to surrounding hip tissue.
Also today at the 2013 AAOS Annual meeting, the educational session "Optimizing Management of Patients with Metal-on-metal Hips," featured seven orthopaedic experts discussing the identification and treatment of MoM hip failure.
In December 2012, the Academy issued an Information Statement on Metal-on-metal Hip Arthroplasty (replacement) recommending a "low threshold" for commencing the evaluation of a patient with an MoM hip replacement, as "early recognition and diagnosis will facilitate the initiation of appropriate treatment prior to significant adverse biological reactions." The statement also provides a detailed overview of various diagnostic and treatment methods to limit patient discomfort, and outlines when to quickly initiate treatment, and if necessary revision.Read more about AAOS: http://www.aaos.org

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
