Cut off values of bone mineral density defining postmenopausal women with bone fractures
Article Abstract:
A bone mineral density (BMD) boundary value of 0.310 grams per square centimeter (g/cm2) may prove useful in predicting the risk for non-spinal bone injury in post-menopausal women. BMD measures the concentration of bone mass at a specific site and is used to assess bone strength. Researchers compared BMD values at two separate arm locations of 398 post-menopausal women with no bone injury history and 354 post-menopausal women with a history of at least two bone injuries. The women with no history of bone injury had significantly higher BMD measurements at both locations and also weighed significantly more than the women with no history of bone injury. Women with a history of bone injury tended to have BMD values below 0.310 g/cm2. BMD measurements made on the arm at a point closest to the wrist had the greatest correlation with bone injury risk.

Clinical evolution of sacral stress fractures: influence of additional pelvic fractures
Article Abstract:
Patients with sacral fractures may have symptoms significantly longer if they have additional pelvic fractures. The sacrum is the triangular bone just below the lumbar vertebrae of the spine. Among 14 osteoporosis patients between 48 and 80 years old with a sacral fracture, six had additional pelvic fractures. Patients with additional pelvic fractures experienced symptoms for an average of 30 weeks, compared with an average of three weeks for patients without additional pelvic fractures. Lower back pain was the most common symptom of a sacral fracture. The most common symptom of additional pelvic fractures was groin pain. Most of the patients had other types of fractures that occurred before or after the sacral fracture. Osteoporosis is decreased bone mineral density. Patients with osteoporosis have a higher risk of certain types of fractures.

How do bisphosphonates prevent fractures?
Article Abstract:
Even though several theories have been proposed to explain the observed protective action of bisphosphonates in reducing fracture risk, the exact biological mechanism is as yet unclear. Evidence suggests that these medications may, at some level, reverse the bone damage done by osteoporosis. Bisphosphonates may strengthen the existing internal bone structure or interfere with the bone loss process. These medications may also act in reducing the porous nature of the outer bone structure or improve bone mineral content.
