Lumbar fusion has long-term benefits

15.12.2008
Lumbar fusion is becoming an increasingly common treatment for low-back pain, but its long-term effects are relatively unknown. A doctoral thesis from the Swedish medical university Karolinska Institutet now shows that the long-term effects are superior to those of physiotherapy.

Chronic low-back pain is treated increasingly often with lumbar fusion, by which several lower back vertebrae are fused in a way that has little impact on the back’s overall mobility. Lumbar fusion has been shown to relieve pain in the short term, but no studies have examined the long-term effects of the operation and compared them with alternative, non-surgical treatments like physiotherapy.

Per Ekman is a surgeon at Stockholm South General Hospital (Södersjukhuset), and has shown in his doctoral thesis that patients who have undergone lumbar fusion also improve in the longer term. His results are based on an evaluation of 111 patients, randomly assigned treatment with lumbar fusion or physiotherapy. On a follow-up nine years later, 76 per cent of the surgical group stated that they felt better than before the operation, compared with only 50 per cent of the physiotherapy group.

“Whether lumbar fusion should be used at all for this type of back pain has long been the subject of much debate,” says Dr Ekman. “My studies suggest that most patients who have undergone lumbar fusion actually feel better, and that the operation carries no great risk. However, long-term improvements are often relatively modest, and the operation should also continue to be used as a complement to physiotherapy when this treatment doesn’t help.”

His thesis shows that men, the physically active and the gainfully employed have somewhat higher chances of benefitting from the operation than others.

“This tells us something, but unfortunately there are still no good methods for finding those with the best chances of responding well to the operation,” says Dr Ekman.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
