As the age of an individual advances, the bones start becoming weak and porous. This is known as porous bones or osteoporosis. This is an unavoidable situation in the life of any human being. Such bones can break even with any minor injury. Usually, the regions affected are the wrist, the back and the hip. “Prevention is better than cure”. It is better to prevent a fracture than to treat it. Prediction of a fracture in the future is possible by looking at certain risk factors in relation to any individual as well as examination by a machine. The said investigation is known as “Bone densitometry”.
Currently, the best method of assessing osteoporosis is measurement of Bone Mineral Density (BMD) using the bone densitometer. This is a safe, useful, reliable and affordable tool without the risk of the radiation hazard. Prediction of the future fracture risk is excellent. The bone densitometry has got diagnostic as well as prognostic important.
By knowing bone density, one can decide whether to start the treatment to prevent and/or postpone the onset of osteoporosis with different medicines. Once the treatment is started, follow up study of bone density will indicate how long to continue the treatment and when to stop medication. Hence, follow up densitometry is essential and helpful , especially when the patient is on (Hormone Replacement Therapy (HRT). Once the bone densitometry is performed, the report indicates whether the person has normal, sub–normal or abnormal bone density.
Accordingly, different medicines including Calcium, Vitamin D and other specific bone strengthening medicines are started by the doctors. Postmenopausal osteoporosis is managed by giving HRT.
