Osteoporosis treatment options fall into two basic buckets: the things we do every day, and the medicines that change how our bone rebuilds itself. Both matter and neither one does the whole job alone.
As a hip and knee replacement surgeon, I’m usually not the doctor writing the prescription for osteoporosis treatment medications. Your primary care physician, rheumatologist, or endocrinologist typically manage those, but I am often the first person who sees what thin bone costs.
What Are the Main Osteoporosis Treatment Options?
There are five osteoporosis treatment options that meaningfully lower your fracture risk:
- Calcium and vitamin D to supply the raw material.
- Weight-bearing and balance exercise to load bone and steady you.
- Fall prevention at home, since most fractures start with a fall.
- Bone-preserving (antiresorptive) medication to slow bone breakdown.
- Bone-building (anabolic) medication to add new bone.
Almost nobody uses just one. Mild bone loss with no fractures may need only the first three. A broken hip and a T-score of minus 3.0 often includes all five.
How Are Osteoporosis Treatment Options Chosen?
Your doctor weighs how much bone you have lost, whether you have already fractured, your kidney function, your dental health, and your other conditions. Sex and age matter too, since some drugs are approved only for women.
Preference counts too. A daily pill, a twice-yearly shot, and a yearly infusion all work; the best one is the one you will stay on. AAOS OrthoInfo keeps a plain-language rundown of each drug class.
Why Does a Hip and Knee Surgeon Talk About Osteoporosis?
Because I meet the fracture before anyone meets the diagnosis. After more than twenty years and 700 or more joint replacements a year, I have lost count of the patients who arrive with a broken hip and a bone density scan nobody ever ordered.
Thin bone also changes the operation. It influenes how I fix an implant, whether I use cement, and how carefully I handle the femur so it does not crack.
Here is what I tell my patients across Franklin, Nashville, and Columbia: a broken wrist at 62 is not bad luck. It is a warning shot. Get the scan, and read up on how osteoporosis leads to fractures.
When Does Osteoporosis Need Medication?
Medication is recommended after a hip or spine fracture from a standing-height fall, when a DXA scan shows a T-score of minus 2.5 or lower, or when a T-score between minus 1.0 and minus 2.5 pairs with a high fracture-risk score.
Below that line, diet and exercise are reasonable first steps. Above it, they are not enough alone.
What Does a T-Score Actually Mean?
A T-score compares your bone density with that of a healthy young adult. Minus 1.0 and higher is normal. Minus 1.0 to minus 2.5 is osteopenia, meaning bone loss that has not yet reached the osteoporosis threshold. Minus 2.5 and lower is osteoporosis.
The scan is painless, takes about ten minutes, and uses less radiation than a chest X-ray.
How Does a FRAX Score Change the Decision?
FRAX is a free online calculator that estimates your ten-year risk of breaking a bone. It folds in age, sex, weight, smoking, alcohol, steroid use, prior fractures, and hip bone density.
Most guidelines suggest treating when FRAX predicts a ten-year risk above 20 percent for a major fracture or above 3 percent for a hip fracture, a threshold echoed by the Bone Health and Osteoporosis Foundation. That is how a patient with borderline numbers ends up on medication anyway.
Which Osteoporosis Medicines Are Usually Tried First?
Bisphosphonates are the usual first choice. They have the longest track record, the widest safety data, and cheap generic versions.
Bisphosphonates: The Usual Starting Point
These medicines slow the cells that break bone down: alendronate (a weekly pill), risedronate (weekly or monthly), ibandronate (a monthly pill or quarterly infusion), and zoledronic acid (a yearly infusion).
The pills are absorbed poorly, so the instructions matter. Take one with a full glass of plain water, first thing in the morning, on an empty stomach, and stay upright without eating for 30 to 60 minutes.
Heartburn is the usual complaint. Two rare problems get attention: osteonecrosis of the jaw (jawbone that will not heal, usually after a dental extraction) and atypical femur fracture (a crack in the thighbone that starts as a dull thigh or groin ache). Both become more likely the longer you stay on treatment.
If pills upset your stomach, the infusion forms work just as well.
Denosumab: A Different Way to Slow Bone Loss
Denosumab is an antibody injected under the skin every six months. It blocks a signal that tells bone-eating cells to form, and it is often used when kidney function rules out a bisphosphonate.
The evidence is strong. In a trial of 7,868 postmenopausal women, denosumab lowered new spine fractures by 68 percent and hip fractures by 40 percent over three years.
One warning I repeat every time: do not simply stop denosumab. Bone loss rebounds quickly, and spine fractures can follow. Your doctor should transition you to another medicine rather than letting the injections lapse.
Which Osteoporosis Treatment Options Build New Bone?
Three osteoporosis treatment options add bone rather than just protecting what is left: teriparatide, abaloparatide, and romosozumab. They are reserved for people with very low bone density, prior fractures, or bone loss caused by steroids.
Teriparatide and Abaloparatide
Both are daily self-injections limited to about two years of use. In an 18-month trial, abaloparatide cut new spine fractures by 86 percent and other fractures by 43 percent.
When the course ends, the gains fade unless you follow with a bone-preserving medicine. That handoff is part of the plan.
Romosozumab
Romosozumab is a monthly injection given for 12 months only, usually after a fragility fracture in someone with severe bone loss. It builds bone and slows breakdown.
It is avoided after a recent heart attack or stroke. As with the others, a bisphosphonate or denosumab follows to hold the gains.
What About Hormone-Based Treatments?
Raloxifene acts like estrogen on bone without the same effect on breast and uterine tissue. It lowers spine fracture risk, but it can cause hot flashes and raises the chance of blood clots.
Estrogen was once standard. Because of the clot, stroke, and cancer risks found in the Women’s Health Initiative, hormone therapy is now reserved for women who cannot take other drugs or who need it for menopause symptoms anyway. Calcitonin nasal spray is the weakest of the group and is rarely a first choice.
Which Osteoporosis Treatment Options Do Not Require a Prescription?
Nutrition, exercise, and fall-proofing your house belong in every plan, medication or not.
How Much Calcium and Vitamin D Do You Need?
Adults over 50 are generally advised to get about 1,200 mg of calcium a day and 800 to 1,000 international units of vitamin D. Food first: dairy, canned salmon or sardines with the bones, tofu, kale, and fortified cereals.
Pills are a different question. As I covered in my review of calcium and vitamin D supplements for fractures, they do little for healthy adults but still matter when you have osteoporosis or a measured deficiency. If you do supplement, split the dose; roughly 600 mg at a time absorbs better. The NIH is a solid neutral reference to consider on this topic.
Which Exercise Is Safe for Weak Bones?
Weight-bearing and resistance work two or three times a week, plus daily balance training. Brisk walking, stair climbing, elastic bands, light weights, and tai chi all qualify.
If you already have osteoporosis, skip deep forward bending and hard twisting of the spine, and get cleared by your physician or a physical therapist first. High-impact activity can break a fragile bone rather than strengthen it.
How Do You Prevent the Fall That Breaks the Bone?
Clear the throw rugs and cords. Put grab bars in the shower. Light the hallway to the bathroom. Get your vision checked, and ask your pharmacist which medications cause dizziness. Plain, unglamorous, effective.
How Long Do You Stay on Osteoporosis Medication?
It depends on the drug, because osteoporosis treatment options are not all open-ended. Most women take an oral bisphosphonate for about five years; after that, patients who are doing well may be offered a drug holiday, because the medicine lingers in bone and keeps working for a while.
Denosumab is different. It is continued or deliberately handed off, never simply stopped. Bone-building drugs run one to two years and are always followed by something that protects the gains. Bone density is usually rechecked one to two years after starting treatment.
What Should Middle Tennessee Patients Do Next?
If you have broken a bone from a minor fall, lost height, or are past 65 without ever having a bone density scan, ask for one, then talk through your osteoporosis treatment options with the physician who ordered it. If you are already facing hip replacement or knee replacement, bone quality is part of that conversation too.
My office is at the Bone and Joint Institute of Tennessee, 3000 Edward Curd Lane, Franklin, TN 37067. Call (615) 791-2630 or request a consultation online. We see patients from Franklin, Nashville, Brentwood, Columbia, and across Middle Tennessee.
