Foot Fracture an Early Sign of Osteoporosis?

Amplify’d from www.foothealthfacts.org 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. Osteoporosis is frequently referred to as the “silent crippler” since it often progresses without any symptoms or isn’t diagnosed until a person experiences [...]

Prior Fractures May Raise Older Women’s Odds for Osteoporosis

Amplify’d from www.nlm.nih.gov Older women who suffered bone fractures earlier in life may be at higher risk for osteoporosis today, a new study suggests. When these women develop osteoporosis, their loss in health-related quality of life becomes similar to that experienced by people with arthritis, lung disease, diabetes, and other chronic diseases, said the international [...]

Vitamin A Analogue Medications Not Linked to Fractures

High doses of vitamin A have been linked to broken bones, but a new study has found that medications with a similar structure do not increase fracture risk. Social Bookmarking OptionsBlinklistBloglinesBlogmarksDiggdel.icio.usFacebookFurlMa.gnoliaNewsVineRedditStumbleUponTechnorati

Bone Building Drugs Found Safe and Effective

A new study published in the New England Journal of Medicine finds two bisphosphonates, Fosamax and Reclast, safe and effective for the treatment of osteoporosis. Some studies have prompted concern about the increased risk of a rare fracture near the hip with the use of these bone building drugs. A secondary analysis of data from [...]

Vitamin D and Calcium Reduce Fracture Risk

A new study finds that Vitamin D with calcium supplementation significantly reduces fracture risk, but Vitamin D supplementation alone does not offer much protection. Researchers from Queen’s Medical Center is Nottingham, England evaluated seven randomized, controlled trials with using Vitamin D with calcium or using Vitamin D alone to prevent fracture risk.

Drugs for Bone Loss May Reduce Breast Cancer Risk

Findings from two studies presented at the annual San Antonio Breast Cancer Symposium showed an association between osteoporosis drugs and cancer risk. Data from the Women’s Health Initiative was used to retrospectively evaluate postmenopausal women for close to 8 years. Of the 151,592 women in the study, 2,216 were taking oral bisphosphonates (drugs to prevent [...]

High Impact Sports Improve Bone Density in Older Athletes

A new study from the University of Pittsburgh found that high impact sports increase bone mineral density in older athletes. Although it is well known that weight bearing exercise and impact activities increase bone mineral density and help prevent osteoporosis, little research has been done on older athletes. This study evaluated 560 athletes competing in [...]

Heel Ultrasound May Help Prevent Osteoporotic Fractures

A DEXA scan, dual-energy X-ray absorbitometry scan, is used to identify low bone mineral density. Identifying individuals with low bone mineral density helps to determine future fracture risk. The calcaneus is the heel bone and a calcaneal ultrasound is a technique used to estimate bone mineral density. It is not as accurate as a DEXA [...]

Competitive Cyclists at Risk of Osteoporosis

Bone is composed of minerals, protein and living cells. Calcium and phosphate form an extremely hard crystal-like structure called hydroxyapatite. The protein collagen forms an intricate network of strong fibrous bands to which the crystals attach. The combined properties of the hydroxyapatite and the collagen create the amazing strength of bone. Osteoblasts and osteoclasts are [...]

Impact Exercise Decreases Risk of Fracture & Osteoporosis

Physical activity is the most important factor for the development and maintenance of healthy bones. A study in the July/August issue of Sports Health found weight bearing activities to be effective at increasing bone mineral density and preventing fractures and diseases, such as osteoporosis. It has been know for years that weight bearing activities increase [...]

Space Study Finds Absence of Gravity Stimulates Bone Breakdown

A new study in The Federation of American Societies for Experimental Biology journal found that lack of resistance (gravity) stimulates the activity of the cells which breakdown bone, called osteoclasts. Although it is well known that bones need resistance to stay strong and that higher impact weight bearing exercises help to prevent osteoporosis, this study [...]

Bone Remodeling

Bone does not exist in a static state. Bone is constantly remodeling itself which means that it is breaking down and building back up again. Osteoclasts are the cells which break down bone (called bone resorption), while osteoblasts build bone back up (called ossification). This process allows for bone to restructure and reshape itself and [...]

Key Factor Controlling Bone Breakdown Discovered

One might think that bone is simply a static structure in the body, but on a microscopic level, bone is constantly being broken down and built back up again. Cells called osteoblasts build up bone and cells called osteoclasts break down bone. In diseases such as osteoporosis, bone breakdown by osteoclasts (bone resorption) outpaces build [...]

Diuretics and Fracture Risk in Women

A study in the current issue of the Archives of Internal Medicine evaluated data from the Women’s Health Initiative (1992-1998) for an association between loop diuretics and fracture rate, falls and bone mineral density. The study included 133,855 women (3411 users and 130, 444 nonusers of loop diuretics) who were followed for a mean of [...]
