Osteoporosis – History and Physical
While minimum screening involves getting a bone mineral density (BMD) scan and calculating a FRAX score to determine risk of fracture, a better risk evaluation can be performed by a focused/complete history and physical.
Minimum evaluation of fracture risk
History:
- History of falls or concerned about falling
- Dietary calcium estimation:
- Number of dairy servings x 300 mg + 300 mg in general diet (unless restrictive diet like vegan, keto, etc.)
- Loss of height:
- 1.5 inches or 3.8 cm suggestive of vertebral fracture –> get spine radiograph to confirm
- Weight (especially <51 kg or 112 lbs)
- Medications (particularly glucocorticoids, antiepileptics, heparin)
- Family history of osteoporosis or parent with hip fracture
Physical exam:
- Oral examination (evaluating need for invasive dental work: fractured teeth, periodontal disease, inflammation, extractions or implants needed)
- If invasive dental work needed, await clearance to start antiresorptive/anabolic osteoporosis therapy from treating dentist/surgeon OR at least 3 months from completion of dental work.
- Fall assessment:
- Gait evaluation (abnormal suggest fall risk)
- Sit to stand (difficulty suggests fall risk)
Comprehensive evaluation of fracture risk
History:
Women:
- Weight upon graduation from high school
- Age at menarche and menopause
All:
- Prior fractures in adulthood
- Kidney stones (may suggest hypercalciuria)
- History of falls or concerned about falling
- Exercise (cardiovascular and strength)
- Nutrition/diet with emphasis on calcium intake
- Low weight (<51 kg or 112 lbs) or significant weight loss (>10% fluctuation)
- Loss of height (1.5 inches or 3.8 cm suggestive of vertebral fracture)*
- Medications (particularly glucocorticoids, antiepileptics, heparin)
- Family history of osteoporosis
- Comorbidities:
- chronic inflammatory states, malabsorptive disorders, chronic major organ dysfunction (liver, kidney, heart, lungs),GERD/esophagitis/dysphagia, diabetes, thyroid dysfunction, parathyroid dysfunction, hypogonadal states
- Smoking
- Alcohol use
Physical
- Weight and BMI
- Oral examination (evaluating need for invasive dental work: fractured teeth, periodontal disease, inflammation, extractions or implants needed)
- If invasive dental work needed, await clearance to start antiresorptive/anabolic osteoporosis therapy from treating dentist/surgeon OR at least 3 months from completion of dental work.
- Spine tenderness (suggestive of vertebral fractures)*
- Fall assessment:
- Gait evaluation (abnormal suggest fall risk)
- Sit to stand (difficulty suggests fall risk)
- Rib-pelvis distance (less than 2 finger widths suggestive of vertebral fracture) or wall-occiput distance (>0cm suggestive of vertebral fracture)*
*If present, raises concern for vertebral fracture. Obtain spine radiograph to confirm.
