Osteoporosis and Fragility Fracture

—

In one line

·Bones become thin and full of tiny holes inside, so they break from small bumps or falls that would never hurt a healthy person.

—

Normal physiology

·Bone is living tissue that rebuilds itself every day. Osteoclasts (digger cells) carve out old bone, and osteoblasts (builder cells) fill the space back in with fresh, strong bone. This balance keeps bones thick, dense, and able to hold your weight without cracking.

—

What goes wrong

·The digger cells speed up or the builder cells slow down, so more bone gets carved out than gets filled back in. Over years, the bone becomes thin and full of holes inside like a sponge losing its struts, even though it looks normal on the outside and you feel fine.

Hallmark signs

·Silent bone loss with no pain or warning
·Fracture from a minor fall or bump (fragility fracture)
·Loss of height over time (getting shorter)
·Sudden sharp back pain (especially mid or lower back)
·Stooped or hunched posture (kyphosis)
·Bone pain or tenderness in the spine, hips, or ribs
·Fracture that happens with little or no injury
·Risk factors present: being postmenopausal, low body weight, smoking, heavy alcohol use, long-term steroid use, or family history of osteoporosis or fractures

Red flags · escalate now

·Fracture from a fall from standing height or less (suggests severe bone fragility and very high risk for more fractures)
·Sudden severe back pain after bending, lifting, or coughing (may be a vertebral compression fracture—needs imaging right away)
·Loss of more than 1.5 inches in height or new stooped posture (suggests multiple spine fractures have already happened)
·Hip fracture (very high risk for disability and death, especially in older adults—about 20% of hip fracture patients die within one year)
·Multiple fractures or fractures in unusual places like the ribs or pelvis (may signal severe osteoporosis or a secondary cause like cancer, hyperparathyroidism, or multiple myeloma)

Treatment

·Calcium 1000–1200 mg daily (from diet + supplement if needed) and vitamin D 800–1000 IU daily
·Weight-bearing and resistance exercise (walking, jogging, dancing, lifting weights) most days
·Bisphosphonates (alendronate, risedronate, or zoledronic acid) for T-score ≤ -2.5, prior fragility fracture, or high FRAX score
·Fall prevention — home safety check (remove rugs, add grab bars, improve lighting), vision correction, balance training, and review medications that cause dizziness (sedatives, blood-pressure pills)
·Denosumab (Prolia) 60 mg subcutaneous every 6 months, if bisphosphonates fail, cause side effects, or cannot be used (severe kidney disease)
·Teriparatide (Forteo) or abaloparatide daily injection, or romosozumab (Evenity) monthly injection, for very high risk (T-score ≤ -3.5, multiple fractures, or fracture on another osteoporosis drug)
·Treat secondary causes — taper or switch off glucocorticoids if possible; replace testosterone in men with levels < 300 ng/dL; correct hyperthyroidism, hyperparathyroidism, or malabsorption

NCLEX trap

·Always get an X-ray or other scan of the spine or hip first to find the break, then treat both the fracture and the weak bones together. Pain alone does not tell you if a bone snapped or how serious it is.
·Screen any patient with risk factors — menopause, long-term prednisone (a steroid pill), past fractures, low body weight, smoking, heavy alcohol, or low testosterone in men — even if they look young or healthy. Osteoporosis does not wait for old age.
·Bisphosphonates (such as alendronate or risedronate) work best over 5 to 10 years of steady use, then the doctor may pause treatment (called a 'drug holiday') to see if the bone stays strong. Stopping early leaves the bone weak and ready to break again.
·If a patient with osteoporosis falls and has hip or back pain afterward, always get imaging right away. Sometimes the first X-ray looks normal but a repeat X-ray a few days later or an MRI will show the hidden break.
·Use a DEXA scan to measure bone density; start bisphosphonates only if the T-score is minus 2.5 or lower (that is osteoporosis) or if a fragility fracture already happened. Calcium and vitamin D alone do not stop bone from crumbling once osteoporosis sets in.
·Treat hip fractures in osteoporosis as urgent and get patients to rehab fast, because being stuck in bed after a fracture causes pneumonia, blood clots, pressure sores, and death. Surgery should happen within 24 to 48 hours if the patient is stable enough.
