JBJS 'Watch' cites head-neck troubles with modular hip implants

Call for further research to better understand and prevent potentially catastrophic complications


2015-08-27
(Press-News.org) Needham, MA.-JBJS Case Connector, an online case report journal published by The Journal of Bone and Joint Surgery, has issued a "Watch" regarding relatively rare but potentially catastrophic complications from failure of modular head-neck prostheses commonly used in hip-replacement surgery. The arthroplasty community currently feels that the advantages gained from modularity in hip implants outweigh the risks, but this Watch raises that risk-benefit question again. The decision to issue the Watch was prompted by a case report by Swann et al. in the August 26, 2015 JBJS Case Connector and a report by Arvinte et al. in the April 22, 2015 JBJS Case Connector. Those two reports described three patients who experienced a complete head-neck dissociation seven to fourteen years after hip replacements that used modular components. The Watch also includes relevant findings from elsewhere in the recent orthopaedic literature to help surgeons better understand and minimize the risks.

In the August 26, 2015 edition of JBJS Case Connector, Swann et al. described two patients who experienced sudden head-neck dissociation seven years after hip-replacement surgery. In the April 22, 2015 JBJS Case Connector, Arvinte et al. reported on a patient who presented with a similar problem fourteen years after receiving a modular hip replacement.

The head-neck failures described in this Watch represent a unique opportunity for orthopaedists and industry to work together to conduct multicenter retrieval studies to better understand, and prevent, these rare but serious outcomes.

"The publication of 'Watches' helps fulfill our mission to serve the orthopaedic community," commented Marc Swiontkowski, MD, Editor-in-Chief of JBJS and co-editor of JBJS Case Connector. "The 'Watch' designation may encourage the orthopaedic community to either demonstrate that these are isolated, unrelated cases or sharpen the focus further by rigorously evaluating the intervention and/or reporting related cases."

Common 'heart attack' blood test may predict future hypertension

2015-08-27
Analysis of blood samples from more than 5,000 people suggests that a more sensitive version of a blood test long used to verify heart muscle damage from heart attacks could also identify people on their way to developing hypertension well before the so-called silent killer shows up on a blood pressure machine. Results of the federally funded study, led by Johns Hopkins investigators, found that people with subtle elevations in cardiac troponin T -- at levels well below the ranges detectable on the standard version of this "heart attack" test -- were more likely to be ...

Clinical trials of dogs with cancer could lead to better treatments for humans

2015-08-26
Dogs get cancer, too. And they have even fewer treatment options than their human owners do. But an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, offers a glimmer of hope. It explores how clinical trials on man's best friend could be a win-win for both dogs and people. Judith Lavelle, an intern at C&EN, notes that only a small percentage of potential human cancer drugs get approved by the U.S. Food and Drug Administration. Many of them fail when tested in people in clinical trials. A major reason for this late ...

This week from AGU: Mars' ice, Earth's mantle & 5 new research papers

GeoSpace Terraced craters: Windows into Mars' icy past Just beneath Mars' dirt surface, or regolith, researchers found an enormous slab of water ice, measuring 40 meters (130 feet) thick, and covering an area equivalent to that of California and Texas combined, according to a new study published today in Geophysical Research Letters. Eos.org What lies deep in the mantle below? For decades, scientists have probed Earth's remote mantle by analyzing how seismic waves of distant earthquakes pass through it. But we are still challenged by the technique's limitations. New ...

Researchers reveal how a common mutation causes neurodegenerative disease

2015-08-26
WORCESTER, MA -- Researchers have determined how the most common gene mutation in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) disrupts normal cell function, providing insight likely to advance efforts to develop targeted therapies for these brain diseases. Scientists from the University of Massachusetts Medical School (UMMS) and St. Jude Children's Research Hospital led the research, which appeared in the science journal Nature. Investigators reported evidence that mutation of C9ORF72 interferes with the movement of RNAs and proteins into and ...

New survey on Americans' views on papal encyclical on climate change

2015-08-26
A new national survey conducted by The Associated Press-NORC Center for Public Affairs Research and researchers at Yale University found that fewer than 1 in 3 Americans, and 40 percent of Catholics, are aware of Pope Francis's efforts to publicize global warming as a priority issue for the Catholic Church. While there is relatively low awareness of the papal encyclical, a majority of Americans say it is appropriate for the pope to take a public position on the issue of global warming. This is true even though very few Americans consider global warming as an issue of religion, ...

ORNL chemical sampling interface features simplicity, speed

Paralysis: Primates recover better than rodents

2015-08-26
Monkeys and humans exhibit greater motor recovery than rats after similar spinal cord injury, according to a study conducted in Grégoire Courtine's lab at EPFL. The study results have been published in Science Translational Medicine. Spontaneous improvement occurs during the first six months after a spinal cord injury, allowing a hemiplegic patient to recover partial motor control. The researchers are using this observation to improve clinical trials and patient therapies. The neuronal mechanisms underlying this extensive recovery in primates are nearly absent in ...

New 'mutation-tracking' blood test could predict breast cancer relapse months in advance

2015-08-26
Scientists have developed a blood test for breast cancer able to identify which patients will suffer a relapse after treatment, months before tumours are visible on hospital scans. The test can uncover small numbers of residual cancer cells that have resisted therapy by detecting cancer DNA in the bloodstream. Researchers at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust were able to track key mutations that cancer accumulates as it develops and spreads, without the need for invasive biopsy procedures. They hope that by deciphering ...

DNA sequencing used to identify thousands of fish eggs

2015-08-26
Using DNA sequencing, researchers have accurately painted a clear picture of fish spawning activities in a marine protected area (MPA) and have created a baseline for continuing studies on the effects of climate variability on fish populations. A group of Scripps Institution of Oceanography at UC San Diego researchers led by Ron Burton and Alice Harada collected 260 samples off the Ellen Browning Scripps Memorial Pier over a two-year period and used DNA barcoding to accurately identify over 13,000 fish eggs. This study was also a collaborative effort between the Scripps ...

Self-control saps memory, study says

2015-08-26
DURHAM, N.C. -- You're driving on a busy road and you intend to switch lanes when you suddenly realize that there's a car in your blind spot. You have to put a stop to your lane change -- and quickly. A new study by Duke University researchers suggests that this type of scenario makes a person less likely to remember what halted the action -- for example, the make and model of the car in the blind spot. People and non-human primates excel at "response inhibition." Our sophisticated brains allow us to cancel an action even when it's something engrained, like driving ...
