Amplify’d from www.medicalnewstoday.com Flexible yet rigid like a human bone, and immediately capable of bearing loads: A new kind of implant, made of titanium foam, resembles the inside of a bone in terms of its structural configuration. Not only does this make it less stiff than conventional massive implants. It also promotes ingrowth into surrounding [...]

Researchers in the Netherlands examined the bone mineral density in patients who were recently diagnosed with rheumatoid arthritis after 1 year of treatment with DMARDS, anti-TNF or corticosteroids. The results were part of the BeSt study which compared four different treatments in patients with rheumatoid arthritis. Three hundred and forty two patients were evaluated and [...]

A talar dome lesion is a crater-like defect in the cartilage of the talus (ankle bone) which also affects underlying bone to various degrees. Trauma, such as repeated ankle sprains, is the most common cause, but certain medications, such as oral steroids, and metabolic or genetic causes may also play a role. Ankle sprains cause [...]

A team of researchers at the National Institute of Health have located bone generating stem cells in the end of the shin bone and the spine in mice. The researchers also identified genetic triggers and factors which control the growth of the stem cells. Researchers have know that bone marrow stem cells can develop into [...]

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 [...]

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 [...]

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 [...]

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 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 [...]

In a recent study evaluating alcohol intake and bone mineral density, researchers found that moderate alcohol intake in older men and postmenopausal women is associated with greater bone mineral density. The study data was obtained from the Framingham Study and included 1182 men, 1289 postmenopausal women and 248 premenopausal women. Bone mineral density measurements were [...]

3D CAT scans help doctors better visualize broken bones in the foot. In the image to the left, multiple fracture fragments of the heel bone are better visualized in the 3D scan than in an X-ray.

Bone grafts have multiple uses in foot and ankle surgery. Surgeons may use them for repairing complex fractures, filling in voids or defects in the bone or assisting in bone fusion surgery. Bone grafts are used to provide structural stability and to stimulate bone healing. In a recently published study in the Journal of Foot [...]

The image above is an X-ray of the foot with the anatomy of the bones defined. The tibia (leg bone), talus (ankle bone), calcaneus (heel bone), navicular, cuneiform (tarsal bones), 1st and 5th metatarsals (long bones in the foot) and the phalanx or phalanges (toe bones).

A study from the University of Athens in Greece determined that adherence to a Mediterranean-style diet has a significant impact on bone mass and skeletal health in women. Features of the Mediterranean diet include high consumption of fish and olive oil, low intakes of red meat, an abundance of plant foods and olive oil, low [...]

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 [...]
