AMY’S STORY – I DIDN’T KNOW I HAD OSTEOPOROSIS
Banner

On the surface Amy thought she has no signs of osteoporosis. She had friends who had suffered broken bones due to a disease called osteoporosis which causes bones to become weak and eventually break. It made her worry. What if that could happen to her too? A friend down the road had moved to a nursing home after a broken hip, and she didn’t want that to suffer the same fate.

So the next time she visited her family doctor she asked about getting tested to see if she was at risk too.

The first step was to look at Amy’s health and medical history which provided clues to her bone health:1

ITEM FTF_tick-wh CASE HISTORY
Older than 50? Yes, Amy is 71 years old – osteoporosis occurs more commonly in postmenopausal women aged over 50 and men aged over 70.
Broken a bone after age 50?   No, she has no history of previous fractures.
Underweight or overweight? Yes, Amy is slightly overweight. Her BMI is 27 kg/m2, which puts her at risk of osteoporosis.
Getting shorter?   No, she has not noticed any lost height. Her doctor measured her height so that it could be compared against in the future.
Parental history?   No, neither of Amy’s parents had osteoporosis or broken bones.
Disorders linked to osteoporosis Yes, Amy has type 2 diabetes mellitus and rheumatoid arthritis.
Medications linked to osteoporosis   None, she doesn’t take any current medications.
Too much alcohol intake or smoker?   No, Amy drinks a glass of wine with dinner a few nights a week and has never smoked.

 

Amy’s responses indicated that she had risk factors for osteoporosis, which puts her at risk of fractures. Her doctor sent her for a bone scan, called a DEXA, to assess her bone mineral density.

What is a DEXA scan?2

DEXA stands for dual-energy X-ray absorptiometry. It is a fast, non-invasive bone scan that measures the density of your bones in the spine and hip. The DEXA scan helps Amy’s doctor to decide if action is needed to improve her bone health. The scan result is called a T-score that compares your bone density with the normal values for healthy young adults. This score will determine if you have normal bones, low bone density or osteoporosis. Amy’s T-score is −2.6 at the femoral neck.

Based on her T-score, Amy’s doctor has diagnosed osteoporosis.

 

How likely is Amy to suffer a broken bone due to osteoporosis?2

Amy’s doctor enters Amy’s T-score and information from her medical history in an online tool, called FRAX (fracture risk assessment tool) which calculates her risk of suffering a broken bone due to osteoporosis. The results say she has almost a 1/10 (8.5%) chance of a major osteoporotic fracture and about a 1/20 (4.5%) chance of a hip fracture in the next 10 years.

Doctor explains her risk of future fracture and recommends starting osteoporosis treatment. Together they will make a bone health plan to protect her from broken bones.
