Diagnosis of Osteoporosis with Bone Mineral Density Measurement
Technologists often diagnose osteoporosis by measuring a patient's bone mineral density (BMD).
Bone mineral density measures the amount of calcium in regions of the bones.
Most methods for measuring BMD (also called bone densitometry) are fast, non-invasive, painless and available on an outpatient basis.
Bone densitometry can also be used to estimate a patient's risk of fracture.
BMD methods involve taking dual energy x rays (DEXA) or CT scans (Osteo CT or QCT) of bones in the spinal column, wrist, arm or leg. These methods compare the numerical density of the bone (calculated from the image), with empirical (historical) data bases of bone density to determine whether a patient has osteoporosis, and often, to what degree.

BMD & measurement
From National Osteoporosis Foundation
www.nof.org/aboutosteoporosis/detectingosteoporosis/diagnosing
www.nof.org/node/42
Your BMD is compared to two norms, "young normal" and "age-matched." Young normal, known as your T-score, compares your BMD to optimal or peak density of a 30-year old healthy adult and determines your fracture risk, which increases as BMD falls below young-normal levels.
Age-matched, known as your Z-score, compares your BMD to what is expected in someone your age and body size.
Among older adults, however, low BMD is common, so comparison with age-matched norms can be misleading.
The difference between your BMD and that of a healthy young adult is referred to as a standard deviation (SD).
As outlined in the World Health Organization's diagnostic categories, individuals whose T-score is within one standard deviation of the "norm" are considered to have normal bone density.
Scores below the "norm" are indicated in negative numbers.
For example, a score from -1 to -2.5 SD below the norm indicates low bone mass, or osteopenia, and a score of more than -2.5 SD below the norm is considered a diagnosis of osteoporosis. For most BMD tests, -1 SD equals a 10-12 percent decrease in bone density.

Several methods are available to measure bone density, but currently the most widely used technique is dual energy xray absorptiometry (DEXA).
This is the method used to determine efficacy in the recent large clinical trials, and to characterize fracture risk in large epidemiological studies.

Guidelines for osteoporosis in CD...
6.1 GENERAL MEASURES
The risk should be explained and general
advice given about exercise (particularly weight
bearing), smoking, alcohol excess, and adequate
dietary calcium. A total daily calcium
intake of 1500 mg should be ensured—a pint of
skimmed milk provides 700 mg. If dietary calcium
is inadequate 500–1000 mg supplemental
calcium should be given (e.g., one or two Calcichew
(Shire, UK) tablets daily). In coeliac
disease the importance of adhering strictly to a
gluten-free diet should be stressed. Vitamin D
de.ciency should be sought and treated if
found. Clinicians usually rely on serum calcium,
phosphate and alkaline phosphatase
measurements. Osteomalacia may still exist
even if these tests are normal. When these tests
are normal and osteomalacia is still suspected
serum 25-hydroxy vitamin D is usually
measured. However, this is expensive and the
cheaper parathormone assay should be considered.
A low normal calcium and an elevated
parathormone indicates secondary hyperparathyroidism
and treatment with calcium (800
mg daily) together with vitamin D (400–800
units daily) should be given.

DECISION POINTS IN THE MANAGEMENT OF ADULT COELIAC DISEASE IN PRIMARY CARE.
Bone mineral density should be measured using dual energy X-ray absorptiometry (DEXA) at the time of diagnosis. The test should then be repeated:
•at the menopause for women
•at the age of 55 for men
•at any age should a fragility fracture occur …

• DEXA at menopause for women, at 55 years for men, at any age following
fragility fracture.
• Advise regular physical activity (A), reduce smoking and alcohol consumption (B).
• Calcium supplement - if poor dietary intake (A).
• Vitamin D supplements - if housebound (A).
• HRT and biphosphonates - if osteoporotic (A).

(e) Bone Abnormalities: Many individuals have osteopenia. It is usual practice to consider bone densitometry scanning on presentation which may be repeated after one to two years of dietary therapy if the initial value is low.
Osteoprosis in post-menopausal women may warrant hormone replacement therapy and the use of bisphosphonates in some individuals.
Calcium supplementation to achieve an intake of 1500mg a day may be considered.

Orwoll E, Ettinger M, Weiss S, et al: Alendronate for the treatment of osteoporosis in men. N Engl J Med 2000; 343:604-610
Alendronate significantly increases bone mineral density (BMD) and helps prevent height loss and vertebral fractures in osteoporotic men.
A trial designed to test the efficacy of alendronate was conducted on osteoporotic men (n = 241; mean age, 63 years).
Study data indicate men who receive 10 mg/day alendronate have a mean increase in BMD at the lumbar spine (7.1 ± 0.3), at the femoral neck (2.5% ± 0.4%), and total body (2.0% ± 0.2%) compared to baseline (P<.001, for all).
Men who receive placebo experience an increase in BMD at the lumbar spine (1.8% ± 0.5%); yet no significant increase is apparent in the femoral neck or total body (P<.001 in relation to baseline BMD).
BMD gains are greater, and vertebral fractures are decreased in the alendronate-treated group.
Men in the alendronate group have a decrease in height of 0.6 mm compared to a 2.4 mm decrease in the placebo group.
The information for this trial was derived from a multicenter, multinational, placebo-controlled, double-blind study...

I wouldn't use these..... they are Bisphosphonates.
Research done at Imperial College showed that these kind of drugs cause tiny fractures throughout the bones
- my mother-in-law ended up with them in her spine and ribs after a few years of being prescribed alendronic acid.
Vitamin K2 is supposed to help keep the bones strong. Found this article.
