Introduction:
Osteoporosis is the most common skeletal disorder and is considered a risk of fracture. Most medication used for the treatment of osteoporosis are antiresorptive; however strontium therapy in postmenopausal women has shown a double effect on resorption and bone formation.
Objective:
To evaluate the effect of strontium on bone mineral density (BMD) and circulating biochemical markers of bone turnover in postmenopausal women who had a decreased BMD.
Material And Methods:
A prospective study was carried out in 23 postmenopausal women who had decreased BMD, who received daily strontium orally by night during 12 months. Evaluation of BMD at lumbar spine and hip as well as biochemical markers in blood for bone turnover before and during therapy.
Results:
BMD at the spine (0.755 +/- 0.104 to 0.792 +/- 0.094, p < 0.05) and hip (0.833 +/- 0.096 to 0.856 +/- 0.100, p < 0.05) increased significantly after 12 months of treatment. Bone turnover markers showed a decrement of osteocalcin, by contrast the specific alkaline phosphatase increased after 6 months of therapy; however C-terminal telopeptide of type 1 collagen was not modified.
Conclusions:
Strontium ranelate increased significantly BMD at the spine and at the hip in postmenopausal women and simultaneously improved bone turnover estimated by circulating bone markers.

01:29Bone Disorders
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...

Calcium and Phosphorus
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...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
