SAN FRANCISCO – The benefits of exercise in minimizing pain and improving mobility for individuals living with osteoarthritis has been well documented.

SAN FRANCISCO —There is growing evidence that supports an association between atypical fractures of the femur– a rare break of the thigh bone, typically without trauma – and the use of bisphosphonates, drugs proven to enhance bone density and reduce fracture incidence caused by osteoporosis.

A new study has demonstrated that a procedure wherein healthy cartilage is transplanted to fix an area of damaged cartilage (osteoarticular cartilage transplantation or OATS procedure) is superior to the standard of care for repairing cartilage defects. It is thought that fixing such lesions may ultimately help to prevent the onset of osteoarthritis, and get athletic individuals back to sporting activities reliably. The study by Hospital for Special Surgery researchers was reported at the annual meeting of the American Academy of Orthopaedic Surgeons, Feb. 7-11.

In low- and middle-income countries, mild cognitive impairment—an intermediate state between normal signs of cognitive aging, such as becoming increasingly forgetful, and dementia, which may or may not progress—is consistently associated with higher disability and with neuropsychiatric symptoms but not with most socio-demographic factors, according to a large study published in this week's PLoS Medicine.

SAN FRANCISCO – Previous studies have found that human behavior during a recession is remarkably different than that during a bullish economy. For example, people tend to spend more time focused on working and less time engaging in leisure and recreation activities, resulting in fewer motor vehicle and other accidents.

According to a 10-year study at a Level 1 regional trauma center, presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), economic trends do impact orthopedic trauma volume.

SAN FRANCISCO – Wrist fractures, also called distal radius fractures (DRF), are among the most common osteoporosis-related fractures occurring on average 15 years earlier than hip fractures. As vitamin D deficiency has recently been linked with muscle weakness, increased fall risks, and bone fractures, investigators sought to determine the prevalence of vitamin D deficiency among post menopausal women with DRF.

(PHILADELPHIA) – Researchers at the Rothman Institute at Jefferson examined data on patients being treated for lumbar stenosis and the degenerative spine condition spondylolisthesis and found that patients who received epidural steroid injections (ESI) had a higher rate of crossover to surgery and fared worse in physical health and bodily pain versus those who did not receive ESI, dispelling their pre-study hypothesis.

How can insurers justify spending hundreds of thousands of dollars per patient per year on "orphan drugs" – extremely expensive medications for rare conditions that are mostly chronic and life-threatening -- when this money could provide greater overall health benefit if spread out among many other patients? Those spending decisions reflect the "rule of rescue," the value that our society places on saving lives in immediate danger at any expense.

SAN FRANCISCO -- Poor emotional health and morbid obesity are associated with less functional gain following total knee replacement (TKR) surgery. In the new study, "Can Telephone Support During Post-TKR Rehabilitation Improve Post-op Function: A Randomized Controlled Trial," presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), approximately 180 patients were categorized by gender, body mass index (BMI) and emotional health.

The collapse of the Soviet Union in 1992 brought an influx of Soviet mathematicians to U.S. institutions, and those scholars' differing areas of specialization have changed the way math is studied and taught in this country, according to new research by University of Notre Dame Economist Kirk Doran and a colleague from Harvard.

Medical researchers at the University of Alberta reviewed the medical records of more than 100 patients who had a liver scarring condition and discovered those who were losing muscle were more apt to die while waiting for a liver transplant. These cirrhosis patients were placed at a lower spot on the transplant list because they had a higher functioning liver and were seemingly less sick than others with the same condition, based on scoring systems physicians commonly use today.

Los Angeles, CA (February 6, 2012) While researchers have long set to determine if there is a tie between race and teenage pregnancy, according to a new study, equating black teenagers with the problem of teenage pregnancy is a misrepresentation of today's real­ity. This new study is detailed in the article, "Black Teenage Pregnancy: A Dynamic Social Problem," published in SAGE Open.

DURHAM, N.H. – Americans' knowledge of facts about the polar regions of the globe has increased since 2006, but this increase in knowledge has not translated into more concern about changing polar environments, according to new research from the Carsey Institute at the University of New Hampshire.

New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that 77 percent of trauma patients had deficient or insufficient levels of vitamin D.

Researchers have linked a lack of vitamin D with muscle weakness, bone fractures, and the inability of bones to fully heal. In a new study, investigators sought to determine the prevalence of vitamin D deficiency among orthopaedic trauma patients.

New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) highlights the benefits of total knee replacement (TKR) in elderly patients with osteoarthritis, including a lower probability of heart failure and mortality.
