The adult human skeleton undergoes constant remodeling, with new bone forming at sites that have been broken down by a precise process called resorption. During remodeling, skeletal stem cells are recruited to resorption sites and directed to differentiate into bone-forming cells. Osteoporosis, a condition characterized by weak and fragile bones, develops when there is an imbalance in the remodeling process and more bone is lost than replaced. Now, new research published by Cell Press in the...

A daily dose of whole body vibration may help reduce the usual bone density loss that occurs with age, Medical College of Georgia researchers report. Twelve weeks of daily, 30-minute sessions in 18-month old male mice "“ which equate to 55- to 65-year-old humans "“ appear to forestall the expected annual loss that can result in fractures, disability and death. Dr. Karl H. Wenger, biomedical engineer in the MCG Schools of Graduate Studies and Medicine, reported the findings with...

FlexBone seen as potential replacement for current bone transplantations With a failure rate as high as 50 percent, bone tissue grafts pose a significant obstacle to orthopedic surgeons attempting to repair complex fractures or large areas of bone loss, such as those often caused by trauma and cancer. Current synthetic substitutes rarely possess the bone-like properties needed for successful grafting and are often difficult for surgeons to manipulate in the operating room. In response to...

(Ivanhoe Newswire) --  A new study shows that women with high T-scores don't need screening every two years, but at least every ten years. "If a woman's bone density at age 67 is very good, then she doesn't need to be re-screened in two years or three years, because we're not likely to see much change," Margaret L. Gourlay, MD, MPH of the University of North Carolina at Chapel Hill School of Medicine and author of this study was quoted as saying. "Our study found it would take about 16...

EAST HANOVER, N.J., Oct. 16 /PRNewswire/ -- Novartis announced today that new six-year data reinforce the long-term efficacy and safety profile of once-yearly Reclast® (zoledronic acid) injection in postmenopausal women with osteoporosis.(1) The study of more than 1,200 women was presented this weekend at the annual meeting of the American Society for Bone and Mineral Research (ASBMR) in Toronto, ON, Canada. The study showed that Reclast maintained bone mass in...

(Ivanhoe Newswire) --A new virtual bone biopsy may be a key tool to identify future bone problems for men with prostate cancer. Prostate cancer is the second most common cancer in men worldwide. The most commonly known treatment for this disease is androgen deprivation therapy or ADT. ADT suppresses or blocks the production or action of male sex hormones. But the same thing that has been used to treat cancer for years is actually associated with the decay of cortical and trabecular bone....

(Ivanhoe Newswire) "“ A simple ultrasound can speed up the healing of fractures. The use of low-intensity pulsed ultrasound (LIPUS) in patients with tibial fractures, which weren't healing as quickly as usual, resulted in 34% greater bone mineral density (BMD) in the fracture area after 16 weeks than use of a sham device. The researchers tested LIPUS in 51 patients and 50 controls. "These findings demonstrate significantly greater progress toward bone healing after LIPUS treatment...

PITTSBURGH Oct. 11 /PRNewswire/ -- October 20 is World Osteoporosis Day. Most people know that osteoporosis is a condition that affects many older women. Though osteoporosis isn't as common in men -- because most men have naturally larger and stronger bones -- they can get it, too. Here are some tips to help women and men keep their bones strong: Eat right. A diet with enough calcium and vitamin D helps keep bones strong. According to the National Osteoporosis Foundation, adults over...

Ultrasound can speed the healing of fractures. A randomized controlled trial reported in the open access journal BMC Musculoskeletal Disorders has found that the use of low-intensity pulsed ultrasound (LIPUS) in patients with tibial fractures which showed inadequate progress toward healing resulted in 34% greater bone mineral density (BMD) in the fracture area after 16 weeks than use of a sham device. Jon E. Block, Ph.D. worked with a team of researchers from University Hospital Marburg and...

Foot surgeons urge patients not to ignore foot pain CHICAGO, Oct. 5 /PRNewswire/ -- Unexplained foot fractures may be the first sign of osteoporosis, a bone thinning disease which affects over 28 million Americans and accounts for 1.5 million bone fractures a year. According to the American College of Foot and Ankle Surgeons, osteoporosis is frequently referred to as the "silent crippler" since it often progresses without any symptoms or isn't diagnosed until a person experiences pain...
