MRI may predict adverse tissue reaction in metal-on-metal hip replacement patients

19.03.2013
Magnetic Resonance Imaging (MRI) can detect a failing, or potentially failing, metal-on-metal hip implant (MoM) early on, according to a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Early detection can result in timely revision surgery, decreasing the risk for further tissue damage and pain.

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.

A Nation in Motion
More than one in four Americans have bone or joint health problems, making them the greatest cause of lost work days in the U.S. When orthopaedic surgeons restore mobility and reduce pain, they help people get back to work and to independent, productive lives. Orthopaedic surgeons provide a great value, in both human and economic terms; and access to high-quality orthopaedic care keeps this "Nation in Motion."

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
