Several orthopedic surgeons recently analyzed and quantified the most frequently cited papers in lumbar spine surgery and to measure their impact on the entire lumbar spine literature. The results of their effort demonstrate the trends that are occurring specific to this subspecialty in healthcare.

When a wearable low-intensity therapeutic ultrasound device was recently tested on humans, at least 75% of the study subjects who used the device demonstrated a minimum 20% increase in daily activity after receiving 6 weeks of ultrasound therapy daily.

Findings from a study presented recently at the European Congress of Endocrinology suggest that lack of physical activity may not be a cause of obesity, but rather a result of poor motor skills associated with the condition.

Researchers at the Hospital for Special Surgery (HSS) in New York City, per a news release from HSS, recently received a $20,000 grant from the American Orthopedic Foot and Ankle Society to compare total ankle replacement (ankle arthroplasty) and ankle fusion (ankle arthrodesis) surgeries as treatments for ankle arthritis.
Per a news release from Medscape, results from a 20-patient controlled study presented recently at the International Stroke Conference 2015 suggest that vagal nerve stimulation (VNS) could be a safe and feasible aid to rehabilitation in stroke patients.

Researchers at Michigan Technological University report that they hope to use a newly acquired 3D bioprinter to create synthesized nerve tissue. This goal hinges, however, on the successful creation of a “bioink” or printable tissue. The material could help regenerate damaged nerves for patients affected by spinal cord injuries.

A study published in the journal Acta Neuropathologica suggests that head injuries that repeatedly occur during contact sports activities or military service may accelerate the aging process by increasing the build-up of beta amyloid in the brain, leading to an increased likelihood of developing dementia.

Christopher N. Sciamanna, MD, MPH, and colleagues at Penn State College of Medicine have received a $14 million grant from the Patient-Centered Outcomes Research Institute to perform a 3-year study about the effectiveness of an exercise program for seniors who have had a fall-related fracture, per a news release from Penn State Milton S. Hershey Medical Center.

Axons in spinal injuries located before the branch point are likely to regenerate in nearly 90% of cases, according to findings from researchers at the University of California, San Diego. The findings, established using optical live imaging equipment, demonstrate that location of injury is a major component in determining the extent of axon regeneration.

Researchers at the University of Missouri have developed boronicaine, a new compound that, they suggest, offers longer-lasting painkilling effects than, and could be a promising alternative to, such anesthetics as lidocaine to numb pain in targeted areas, according to a release from the University of Missouri (MU) School of Medicine.
Study first author Trent M. Guess, PhD, found that even small changes in the menisci can hinder their ability to perform critical knee functions.
Once viewed as a non-vital part of anatomy, the importance of menisci in knee-joint health has been emphasized by a new study that suggests even small changes in the menisci can hinder their ability to perform critical functions.

Trials to test the use of 3D-printed bones implanted in human bodies are expected to be completed by early summer, while "successful" animal trials reportedly were competed this week. The accomplishment calls attention to the rapid advance of fabricated tissue and underscores China's position as a manufacturer of such materials.

Despite being otherwise healthy, adults age 60 years and older demonstrate high prevalence of both inflammatory and structural abnormalities in an ultrasound-based investigation of the association between inflammation and knee function.

Researchers from Kessler Foundation, West Orange, NJ, have found a link between the inability to recognize emotions expressed by facial features and the white matter damage that occurs after traumatic brain injury (TBI).

Johns Hopkins researchers have developed a software program that works seamlessly with currently available procedures to assist a surgeon's determination of which vertebra is which.
An expanded indication for onabotulinum toxin A (Botox) recently received FDA approval to treat adults with upper limb spasticity. The new approval follows the FDA's nod in 2010 to treat spasticity in the flexor muscles of the elbow, wrist, and fingers in adults, which often occurs after stroke, TBI, or the progression of MS.
Long used as a pain reliever by patents affected by arthritis, acetaminophen was recently tested for its effectiveness in management of spinal pain and osteoarthritis of the hip or knee. Researchers found that the drug underperformed, and even suggested physical treatment as a mainstay solution.

Therapists who treat stroke cases may want to be alert to the psychological state of that patient population, with a recent study showing stroke patients are up to twice as likely to commit suicide as the rest of the population. Risk is especially high within the first 2 years of a stroke, according to the study published in the journal Neurology.
