[ Frequently Asked Questions ](#blog-faqs) 13. [ References ](#references-heading) Three centimeters of documented height loss may signal an unrecognized vertebral fracture—even without back pain. In this case, a routine prescription refill becomes an opportunity to detect skeletal fragility before a disabling fracture occurs. [\[1\]](#cite-1 "Reference [1]") A 68-year-old woman takes omeprazole 20 mg daily for GERD, smokes 15 cigarettes daily, and has a BMI of 19 kg/m². Two weeks after falling onto her right hip, she reports resolved bruising, no current pain, and feeling shorter; examination reveals no focal tenderness. Osteoporosis Risk: Separate Evidence From Assumption ---------------------------------------------------- Her established risk factors include older age, postmenopausal status, smoking, and low body weight. Estrogen deficiency shifts remodeling toward osteoclastic resorption, progressively compromising bone strength. [\[2\]](#cite-2 "Reference [2]") Long-term PPI exposure warrants medication review, but it is not equivalent to proven drug-induced osteoporosis. Observational fracture associations do not establish causality; impaired calcium absorption remains a proposed mechanism rather than a demonstrated explanation in this patient. Review the GERD indication and use the lowest effective dose rather than reflexively stopping necessary therapy. [\[3\]](#cite-3 "Reference [3]") ### Height loss changes the assessment She already qualifies for DXA by age. Her measured 3-cm interval height loss additionally exceeds BHOF's prospective height-loss threshold for vertebral imaging; obtain DXA-based vertebral fracture assessment or lateral thoracic/lumbar radiographs. [\[2\]](#cite-2 "Reference [2]") > Clinical Pearl: Absence of spinal tenderness does not exclude vertebral fracture. Height loss is a diagnostic clue—not simply another osteoporosis risk factor. [\[1\]](#cite-1 "Reference [1]") Investigations: Confirm Fragility and Exclude Mimics ---------------------------------------------------- ### Secondary causes deserve a deliberate search Consider these alternatives or contributors before labeling all low BMD as postmenopausal osteoporosis: - Vitamin D deficiency and osteomalacia. - Hyperparathyroidism, thyroid hormone excess, and CKD-related bone disease. - Malabsorption, including celiac disease. - Plasma-cell disease when anemia, renal dysfunction, or other clinical features suggest it. [\[4\]](#cite-4 "Reference [4]") An initial evaluation includes CBC, albumin-adjusted calcium, creatinine/eGFR, phosphate, magnesium, alkaline phosphatase/liver chemistry, 25-hydroxyvitamin D, and PTH. BHOF also includes 24-hour urinary calcium and creatinine; add TSH, celiac serology, or monoclonal-protein studies according to clinical findings. These tests identify contributors but cannot categorically exclude every secondary cause. [\[1\]](#cite-1 "Reference [1]") ### Interpret the DXA without averaging sites SiteT-score and interpretationFemoral neck−2.6: osteoporosisLumbar spine−2.3: low bone mass The femoral-neck result establishes densitometric osteoporosis; the less abnormal spine does not downgrade the diagnosis. Degenerative changes can artifactually elevate lumbar BMD in older adults, so review scan quality. [\[5\]](#cite-5 "Reference [5]") Treatment is indicated without requiring FRAX to cross another threshold. In US practice, FRAX thresholds of ≥3% hip or ≥20% major osteoporotic fracture probability chiefly guide treatment when T-scores are in the osteopenic range. [\[4\]](#cite-4 "Reference [4]") Alendronate: Match Treatment to Gastrointestinal Risk ----------------------------------------------------- Alendronate is an appropriate first-line option when oral treatment is feasible. It binds bone mineral and suppresses osteoclast-mediated resorption; it is not an anabolic drug. [\[4\]](#cite-4 "Reference [4]") Controlled GERD alone is not an absolute contraindication. Avoid oral therapy with esophageal-emptying disorders or inability to remain upright, correct hypocalcemia, and assess renal function; alendronate is generally unsuitable below creatinine clearance 35 mL/min. Significant esophageal symptoms may favor IV zoledronate if renal function permits. [\[6\]](#cite-6 "Reference [6]") ### Four administration instructions worth checking by teach-back For the standard tablet: 1. Take it immediately after rising, following an overnight fast. 2. Swallow whole with a full glass of plain water—not coffee, juice, or mineral water. 3. Wait at least 30 minutes before food, beverages, supplements, or other oral medicines. 4. Remain upright for at least 30 minutes and until after the first food of the day. [\[6\]](#cite-6 "Reference [6]") New dysphagia, painful swallowing, or worsening heartburn warrants stopping the tablet and clinical assessment. Recheck adherence and tolerability early, and generally repeat DXA after 1–2 years. [\[4\]](#cite-4 "Reference [4]") Five Years Later: Thigh Pain Is a Warning ----------------------------------------- New unexplained mid-thigh aching during prolonged bisphosphonate treatment requires prompt evaluation for **atypical femoral fracture**. Obtain full-length femoral radiographs; persistent suspicion despite negative films warrants MRI, and a confirmed fracture requires contralateral imaging. [\[7\]](#cite-7 "Reference [7]") If confirmed, discontinue alendronate, restrict weight-bearing, and arrange orthopedic and osteoporosis-specialist assessment. Independently, five years of oral therapy should trigger fracture-risk reassessment—not an automatic drug holiday. [\[7\]](#cite-7 "Reference [7]") ### Discuss jaw risk without discouraging treatment ONJ is rare at osteoporosis doses and substantially more frequent with high-dose oncology regimens. Estimates vary; NOGG reports approximately 10–100 cases per 100,000 person-years of bisphosphonate exposure. [\[7\]](#cite-7 "Reference [7]") Encourage oral hygiene, routine dental care, and reporting nonhealing sores or jaw symptoms. Arrange timely treatment of severe dental disease when feasible; necessary dental procedures are not automatically prohibited, and stopping therapy has not been shown to reduce procedural ONJ risk. [\[7\]](#cite-7 "Reference [7]") Clinical Application: Prescribe Fall Prevention ----------------------------------------------- A useful plan extends beyond “be careful”: - Refer for progressive balance, functional, and resistance exercise. - Assess home hazards, lighting, bathroom supports, and footwear. - Review sedating medications, orthostatic symptoms, vision, and gait. [\[8\]](#cite-8 "Reference [8]") Support smoking cessation, adequate nutrition, approximately 1,200 mg/day total calcium, and vitamin D sufficiency. Nutritional supplementation supports osteoporosis care but should not replace evidence-based exercise for fall prevention. [\[1\]](#cite-1 "Reference [1]") Key Points for Board Exams -------------------------- - Use the lowest valid diagnostic-site T-score; do not average sites. [\[5\]](#cite-5 "Reference [5]") - PPI-associated fracture risk does not prove causation. [\[3\]](#cite-3 "Reference [3]") - New thigh pain on bisphosphonates requires imaging. [\[7\]](#cite-7 "Reference [7]") The central lesson is to connect fracture detection, secondary-cause assessment, medication suitability, and fall prevention. A prescription refill should not end before the height-loss finding has a follow-up plan. Frequently Asked Questions ---------------------------- ### Does controlled GERD rule out oral alendronate? No. Assess esophageal disease, symptoms, and ability to follow dosing precautions; controlled reflux alone is not an absolute contraindication. [\[6\]](#cite-6 "Reference [6]") ### Should alendronate automatically stop after five years? No. Reassess fractures, BMD, and overall risk; a monitored holiday is appropriate only for selected patients. [\[7\]](#cite-7 "Reference [7]") ### Could the spine T-score underestimate her osteoporosis? Yes. Degenerative changes may falsely elevate lumbar BMD; the valid femoral-neck T-score of −2.6 already establishes osteoporosis.
