Bone densitometry measures bone density (osteoporosis study).

What is osteoporosis.
Osteoporosis is a disease that causes the thinning down and the weakness of bones. Usually, the bone tissue renews itself by a process where the old tissue is eliminated and replaced by new tissue. In osteoporosis, the old tissue is not replaced by enough new tissue which leads to a loss of bone mass or bone density which can lead to bone fractures after a sprain or a fall. These bone fractures are called a fracture of fragility.

What osteoporosis is not.
Osteoporosis in not necessarily the result of ageing. We often refer to osteoporosis as the “silent thief” because most people ignore that the quality of their bones is deteriorating until they have their first fracture. Unfortunately, after the first fracture, the risk of having another is considerably higher.

Types of fracture

The fractures from osteoporosis can happen in any bone, but the most frequent sites are in the spine, the hip (for example after a fall), and the wrist (for example while extending the arm to absorb a fall).

The vertebral fractures can remain unnoticed until a loss in height or a curved spine occurs. Theses changes happen because the bones of the spine (vertebra) get crushed and shrink gradually. This type of fracture is not always painful. Only one third of all spine fractures are brought to the attention of a doctor.

Prevention is important because it reduces the risk of osteoporosis to a minimum. This includes understanding who is at risk for osteoporosis and establish a treatment quickly to prevent the disease. If the person already has osteoporosis, the early screening is essential to prevent fractures.

The risk factors for osteoporosis include:
• Age : 65 years of age and over
• White or Asian race
• Thin persons
• Early menopause
• Smoking
• Alcohol consumption
