Background:
Osteoporosis-related fractures represent a major health problem. Although spine and hip bone densitometry is the gold standard to assess bone density, this test is not always accesible. The purpose of this study was to describe two options to assess the risk of fracture due to osteoporosis in post-menopausal women assigned to a primary care unit where bone densitometry is not available.
Methods:
A cross-sectional study was conducted in 332 post-menopausal women without diagnosis or treatment for osteoporosis, attending regularly to a primary care unit. A heel bone peripheral densitometry, physical exam and medical history were performed. The assessment of fracture risk was carried out using the FRAX™ method.
Results:
Mean age was 60 ± 8.7 years and body mass index was 28.68 ± 4.24. According to the heel bone peripheral densitometry, 19 (5.7 %) women had osteoporosis (T-score less than or equal to -2.5), 171 (51.8 %) had osteopenia (T-score between -2.5 and less than or equal to -1) and 141 (42.5 %) had normal bone mineral density. According to the FRAX method, 13 (3.9 %) had an increased risk of osteoporotic fracture in a 10-year period and 40 (12 %) of hip fracture.
Conclusions:
There was low concordance in the 10-year risk for major osteoporotic fracture and hip fracture assessed with both the FRAX™ and the peripheral bone densitometry methods.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
01:27Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
