Spinal stenosis involves a narrowing of a passage in the spine through which nerves pass, and it can result in a debilitating pain in the lower back, hips and legs. The surgical solution involves enlarging the opening to relieve the pressure on the nerves, in an operation called a laminectomy, one of the most common operations performed in the U.S.
The study results come from the Spine Patient Outcomes Research Trial sponsored by the National Institutes of Health that involved about 654 patients at 13 treatment centers across the country. Rush was the only medical center in Illinois involved in the study.
The study followed 654 surgical candidate patients with a history of at least 12 weeks of symptoms and spinal stenosis, of whom 398 ultimately received decompressive surgery. After two years, 63 percent of those who had surgery said they had a major improvement in their condition, compared with 29 percent among those who got nonsurgical treatment.
In terms of self-reported pain and function, both groups improved over the two-year period, though the final scores for patient who had surgery were in the 60-point range, while scores for those who stuck with nonsurgical treatments, such as physical therapy, were in the low 40s.
The study separated patients who stuck with their random assignment to surgery or nonsurgery options. The randomized patients’ results were very similar to those who selected one course or the other.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
