UCSF analysis shows newer surgery for neck pain may be better

12.04.2011
A new surgery for cervical disc disease in the neck may restore range of motion and reduce repeat surgeries in some younger patients, according to a team of neurosurgeons from the University of California, San Francisco (UCSF) and several other medical centers that analyzed three large, randomized clinical trials comparing two different surgeries.

More than 200,000 Americans undergo surgery every year to alleviate pain and muscle weakness from the debilitating condition caused by herniated discs in the neck. For some, the team found, arthroplasty may work better.

The results do not suggest that the older surgery is ineffective or unsafe, but that arthroplasty is a viable option for some.

"For people younger than 50 who have cervical disc disease, arthroplasty is a good option," said Praveen Mummaneni, MD, of the Department of Neurosurgery at UCSF.

Mumaneni and his colleagues are presenting their analysis today at the 79th Annual Scientific Meeting of the American Association of Neurological Surgeons in Denver.

Why Fewer Is Better

Neck surgery is not cheap and requires a patient to be placed under general anesthesia and a surgical team to perform the operation in a sterile room. They are typically reserved for patients who have failed to respond to other measures such as physical therapy or drugs, such as steroids.

For decades, the standard of care in this country was a procedure called anterior cervical discectomy and fusion. In this surgery, a surgeon cuts through the front of the neck, accessing the spine and removing the herniated disc, then replacing it with a piece of bone and a plate in the neck. That creates a solid union – or fusion – between two or more vertebrae to strengthen the spine.

Arthroplasty also begins with a surgery to remove the herniated disc. But instead of fusing the spine, the surgeon replaces the missing disc with an artificial one made of steel, plastic or titanium. The idea is that the artificial disc will provide more spine mobility after surgery and less stress on adjacent discs.

While arthroplasty has become more widely used in the United States since the U.S. Food & Drug Administration approved several models of artificial discs in the last few years, it is still performed less often than in Europe, where the procedure has been available for more than a decade.

Here in the United States, the older, surgical fusion technique remains more common – in part because not all insurance companies pay for the newer procedure, as is the case in California.

Both techniques have occasional failures. In the fusion surgery, the bone may not heal, requiring further fusion surgery months or years later. In the arthroplasty surgery, the artificial disk may loosen or not fit well and may need to be replaced.

"Surprising" Results

The new analysis looked at three randomized clinical trials that enrolled 1,213 patients with cervical disc disease at medical centers across the United States – including UCSF.

In the trials, 621 patients received an artificial cervical disc and 592 patients were treated with spinal fusion. The analysis looked at outcomes two years after surgery.

The results were surprising, Mummaneni said: "While the two-year surgical results for both techniques were excellent, the rate of repeat surgery is lower for arthroplasty than for fusion at the two-year timepoint."

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
