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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
