A new study of these patients as adults has found that the benefits have lasted, reveals research from the Sahlgrenska Academy and Sahlgrenska University Hospital presented this week at the International Society of Orthopaedic Surgery and Traumatology (SICOT) annual international conference in Gothenburg.
Spondylolisthesis (forward displacement of a vertebra) in the lumbar spine occurs in 6% of the population and does not usually cause any problems. However, it can lead to back pain and/or sciatica, and in some cases the displacement is more pronounced, known as high-grade spondylolisthesis. The latest study is a long-term follow-up of around 40 patients with high-grade spondylolisthesis who underwent surgery as children to fuse the vertebrae together in order to prevent further movement and the risk of the symptoms worsening. From 1972 to 1985, patients’ vertebrae were fused in situ with no attempt made to correct their position, due to the risk of nerve damage.
“There was debate about how patients might be affected by the back being bent forward as a result of the fusion operation,” says Karin Frennered, PhD (Medicine), a researcher at the Department of Orthopaedics at the Sahlgrenska Academy and consultant at Sahlgrenska University Hospital. “This back position produces an unnatural gait, which could lead to problems in the longer term.”
At the seven-year follow-up, however, patients reported low levels of pain and good function, and the same happened in the new follow-up study after almost 30 years.
“What’s interesting – and remarkable – about the new study is that patients also describe low levels of pain, good function and high quality of life as adults despite the position of the back,” says Frennered.
The researchers will now continue to examine the patients’ posture, gait and X-rays in a bid to produce further scientific evidence for safe surgical techniques that can lead to better treatment strategies for these patients.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
