Learning Objectives Upon completion of this program participants will be able to: 1. Discuss the clinical impact of fractures and the current care gap in osteoporosis. 2. Evaluate a patient s individualized risk of osteoporotic fracture utilizing a practical risk assessment tool. 3. Treat osteoporosis based on the 2010 Osteoporosis Canada guideline. 4. Analyze controversies surrounding osteoporosis therapy.
Definition of Osteoporosis Normal Bone Osteoporotic Bone WHO Definition 1 Osteoporosis is a systemic skeletal disease characterized by low bone density and microarchitectural deterioration of bone tissue with a consequent increase in bone fragility. NIH Definition 2 Osteoporosis is defined as a skeletal disorder characterized by compromised bone strength predisposing a person to an increased risk of fracture. Bone strength reflects the integration of 2 main features: bone density and bone quality. 1. Genant HK et al. Osteoporos Int 1999;10:259-64. 2.

Osteoporotic Fracture = Fragility Fracture He tried a little hip-hop. One hop and he broke a hip.
Fragility Fracture: Definition A fracture occurring spontaneously or following minor trauma such as a fall from standing height or less 1,2 Excluding craniofacial, hand, ankle and foot fractures 1.

2010 Canadian Osteoporosis Guidelines
Who Should Be Screened for Osteoporosis Women (and men) over the age of 50 Any individual with a history of fragility fracture A detailed history and physical exam can help identify individuals at high risk of fractures Papaioannou A, et al CMAJ 2010. *Fracture image courtesy of Dr Robert Josse
Major Risk Factors for Osteoporosis Age 65 years Vertebral compression fracture Fragility fracture after age 40 Family history of osteoporotic fracture (especially maternal hip fracture) Brown JP, Josse RG. CMAJ 2002;167(10 suppl):s1-s34.
Three Steps for Quick Screening in Office 1. ASK Since the last visit... "Have you broken any bones? "Have you fallen? "Have you had prolonged and unusual back pain? "Have you received oral or intravenous steroids (cortisone)?" 2. LOOK - Is there kyphosis? - Ability to perform the Get up and Go Test 3. MEASURE The patient s height Rib to pelvis distance Occiput-to-wall distance EMR reminder tools may help to prompt screening 4 1. Siminoski K et al. Osteoporos Int. 2006;17:290-6. 2.

Screening for Osteoporosis: When to do a BMD 1 Aged 65 years Aged 50-64 years Aged <50 years Everyone One or more risk factors for fracture: o Fragility fracture after age 40 o Parental hip fracture o Vertebral fracture or osteopenia identified on radiography o Medication with high risk of bone loss (i.e. steroids) o Smoking, alcohol ( 3/d) o Disorders associated with osteoporosis (i.e. RA) o Low weight or major weight loss 2 causes of osteoporosis (i.e. malabsorption) Prior fragility fracture Medication with high risk of bone loss Clinical Note: If you are ordering unrelated imaging (e.g. chest x-ray) for your patient, consider adding rule out vertebral fracture on the order 2. 1.

What biochemical tests should be ordered in the assessment of osteoporosis?
Secondary Causes of Osteoporosis
Assessment for Osteoporosis: Recommended Biochemical Tests Calcium, corrected for albumin CBC Creatinine Alkaline phosphatase Thyroid-stimulating hormone Serum protein electrophoresis (for patients with vertebral fractures) 25(OH)D* In clinical practice, these tests help rule out secondary causes of osteoporosis. *Should be measured after 3-4 months of adequate supplementation and should not be repeated if an optimal level (at least 75 nmol/l) is achieved. CBC = complete blood count; 25(OH)D = 25-hydroxyvitamin D Papaioannou A et al. CMAJ 2010; 182:1829-30.

2010 Clinical Practice Guidelines for the Diagnosis and Management of Osteoporosis in Canada Key points: Management of osteoporosis should be guided by an assessment of the patient s absolute risk of osteoporosis-related fractures Fragility fracture increases the risk of further fractures and should be considered in the assessment Lifestyle modifications and pharmacologic therapy should be individualized to enhance adherence to the treatment plan Papaioannou A et al. CMAJ 2010; 182:1829-30.
