Osteoporosis Care for Seniors

A T-score is the result from a DXA (dual-energy X-ray absorptiometry) bone density scan. It compares your bone mineral density (BMD) to that of a healthy 30-year-old of the same sex — the age when bone density peaks. A T-score of 0 means your bone density equals a healthy young adult. Each unit below 0 represents one standard deviation less bone density. The WHO classification: Normal is ≥ −1.0; Osteopenia (low bone mass) is −1.0 to −2.5; Osteoporosis is ≤ −2.5; Severe osteoporosis is ≤ −2.5 with a fragility fracture. FRAX score (available at shef.ac.uk/FRAX) is equally important: it calculates your 10-year probability of a major osteoporotic fracture or hip fracture based on T-score plus clinical risk factors (age, smoking, BMI, steroid use, prior fracture, rheumatoid arthritis, parent with hip fracture). Treatment decisions are based on both T-score and FRAX — a borderline T-score with multiple clinical risk factors may still warrant medication.

The US Preventive Services Task Force (USPSTF) 2018 recommendations: Screen all women aged 65+. Screen postmenopausal women under 65 whose 10-year osteoporotic fracture risk (FRAX score) is ≥ that of a 65-year-old white woman with no additional risk factors (~9.3% 10-year risk). The NOF and AACE also recommend screening men aged 70+, and men 50–69 with clinical risk factors. High-risk groups warranting earlier screening: anyone with a fragility fracture (fracture from standing height or less), long-term steroid use (≥ 5mg prednisone daily for ≥ 3 months), hypogonadism (low estrogen or testosterone), rheumatoid arthritis, malabsorption disorders (celiac disease, Crohn's, gastric bypass), or medications known to reduce BMD (aromatase inhibitors, androgen deprivation therapy, long-term PPIs).

Seniors who are lactose intolerant or avoid dairy can meet calcium needs from: Calcium-fortified non-dairy milk (almond, soy, oat milk — typically 300–350mg per cup, comparable to cow's milk); Canned sardines or salmon with bones (3oz sardines = 325mg calcium); Calcium-set tofu (firm tofu made with calcium sulfate, ½ cup = 250–430mg); Dark leafy greens — collard greens (1 cup cooked = 268mg), bok choy (1 cup cooked = 158mg), kale (1 cup cooked = 94mg) — note: spinach has high oxalate content that blocks calcium absorption; Calcium-fortified orange juice (1 cup = 300–350mg); Almonds (1oz = 76mg); Chia seeds (1oz = 179mg). Note: the recommended total daily intake is 1,200mg for adults 70+, but avoid supplements > 500mg per dose at a time (split doses for better absorption) and avoid supplements if total daily calcium from diet + supplements exceeds 2,000mg (no additional fracture benefit, potential cardiovascular risk).

The ACC/AHA, NOF, and ASBMR consensus is: for oral bisphosphonates (alendronate, risedronate) and zoledronic acid IV, treat for 5 years (oral) or 3 years (IV zoledronic acid), then reassess. A 'drug holiday' of 1–3 years may be appropriate for low-to-moderate risk patients — bisphosphonates are stored in bone and continue working after stopping. High-risk patients (T-score ≤ −2.5 at hip or spine, prior fragility fracture) should continue for up to 10 years oral or 6 years IV. Key safety issue for extended use: atypical femoral fractures (AFF) are stress fractures of the femoral shaft — rare but increased with > 5 years of oral bisphosphonate use. Osteonecrosis of the jaw (ONJ) is another rare risk increased with dental procedures. Important: dental work should ideally be completed before starting bisphosphonates; inform any dentist or oral surgeon of your bisphosphonate use.

Yes, hip fractures in seniors almost universally require hospitalization followed by skilled nursing facility (SNF) care or intensive inpatient rehab. The surgery (hip hemiarthroplasty or total hip replacement) is typically performed within 24–48 hours of admission — delay beyond 48 hours significantly increases mortality. Post-surgery skilled nursing provides: IV antibiotics, wound care, deep vein thrombosis prevention (anticoagulation, compression), pain management, physical therapy to restore ambulation (goal: walking with an assistive device within 24–48 hours of surgery), and occupational therapy for ADL retraining. Medicare Part A covers SNF care after a 3-night qualifying hospital stay (usually easily met with hip fracture). The 1-year mortality after hip fracture is 20–30% in seniors — aggressive rehabilitation and fall prevention after recovery are critical. Most seniors do not return to their prior level of function without intensive PT.

Yes. While osteoporosis is 4x more common in women (and postmenopausal estrogen loss is the primary driver), 2 million American men have osteoporosis and another 12 million have osteopenia. One in four men over 50 will have an osteoporosis-related fracture in their lifetime. Male osteoporosis causes include: age-related bone loss after 70, low testosterone (hypogonadism), long-term steroid use, alcohol use, smoking, calcium/Vitamin D deficiency, and underlying conditions (COPD, IBD, rheumatoid arthritis, celiac). Men should be screened starting at age 70, or earlier if risk factors are present. Bisphosphonates (alendronate and zoledronic acid) are FDA-approved for men with osteoporosis. Denosumab and teriparatide are also approved for men. Testosterone therapy in men with hypogonadism improves BMD but is not a primary osteoporosis treatment.

A fragility fracture is a broken bone caused by forces that would not normally break a healthy bone — specifically, a fall from standing height or less, or even a sneeze or minor twisting motion. The most common fragility fracture sites in seniors: vertebral (spine) fractures — often painless and discovered incidentally on imaging; wrist (Colles fracture) — often from catching a fall; hip fracture — the most life-threatening, with 20–30% 1-year mortality; and proximal humerus (shoulder). A single fragility fracture is a major red flag — it doubles the risk of a future fracture, and subsequent fractures further increase fracture risk exponentially. A vertebral fracture at age 65 carries a 10-year hip fracture risk of approximately 20%. A prior fragility fracture automatically qualifies a patient for osteoporosis medication regardless of T-score. Unfortunately, osteoporosis is severely undertreated — only 20–25% of seniors who sustain a fragility fracture ever receive osteoporosis workup or treatment.
