Anti-inflammatory drugs following hip replacement surgery could harm rather than help

12.09.2006
The use of anti-inflammatory drugs following hip replacement surgery could do more harm than good, according to a new study co-coordinated by The George Institute for International Health in association with orthopedic centres throughout Australian and New Zealand.

The results of the study designed to determine the long-term benefits and risks of anti-inflammatory drugs in patients undergoing hip replacement surgery were published today in the British Medical Journal. The study specifically measured the effects of a short post-operative course of anti-inflammatories on the development of 'ectopic' bone formation related pain and disability, six to twelve months after surgery.

"Ectopic bone is abnormal bone that can form in the soft tissues around the operated hip. This occurs in more than one third of all patients in the months after hip replacement surgery," explained, Dr Marlene Fransen Head, Musculoskeletal Program at The George Institute and Principal Investigator of this study. Many surgeons prescribe anti-inflammatory drugs in the immediate post-operative period to avoid this outcome, or simply as part of a pain management strategy. While the researchers found the use of post-operative ibuprofen, a common anti-inflammatory drug, did indeed greatly reduce the risk of ectopic bone formation, patients reported no greater reductions in hip pain or physical disability six to twelve months after surgery, compared with those not taking the drug. However, they also found evidence suggesting there may be an increased risk of major bleeding events in those taking the drug,

"For this reason, our study shows that recommending a routine course of an anti-inflammatory drug following hip replacement surgery, is not justified."

Chronic osteoarthritis of the hip is common among Australians aged 60 years or older and total hip replacement surgery is a well-established and highly effective treatment. Whilst joint replacement surgery greatly reduces chronic hip pain and improves physical function in most, residual symptoms are common. Over 900 patients from 20 orthopedic surgery centres across Australia and New Zealand participated in this study, half of whom were allocated to receive ibuprofen, a common anti-inflammatory drug, for 14 days commencing immediately after surgery.

"These results provide further evidence that guidelines for routine clinical care in surgery must be based on clinically important outcomes. Without such evidence, the widespread use of routine anti-inflammatory-based treatment after major orthopaedic surgery may well result in harm rather than benefit," Dr Fransen added.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
