Bone Case Study

1. A bone mineral density (BMD) test measures the amount of mineral concentration in a
specific region of the bones in order to determine a persons bone strength or density and
their risk for fractures.

2. The physician uses the BMD test in conjunction with a patient's history to
determine the patient's risk of Osteoporosis. Osteoporosis is a disease that is
characterized by thinning, weak bones. Bone loss is actually a normal event in the human
body. We loose bone when cells (osteoclasts) release stored salts (calcium, phosphorous,
magnesium) from the bone into the blood stream when dietary intake is not providing
adequate amounts. Typically (at least until age 30) we have other cells (osteoblasts) that
come in and repair, repair and build lost bone. Osteoporosis occurs when the osteoclasts
are working faster than the osteoblasts. Eventually the osteoblasts fall further and
further behind leaving thin and brittle bones.

3. Results for the BMD test are given as T-scores and Z-scores. The T-score compares
the results with a healthy young adult of the same gender and the Z- score compares it
with an individual of the same age and gender. A positive or normal result of the BMD
would be 1 standard deviation ( 1/-1) of the T-score mean. A result of 2.5 or greater
