Osteoporosis Treatment to Prevent Fractures: How to Protect Your Bones

Osteoporosis Treatment to Prevent Fractures: How to Protect Your Bones The main purpose of osteoporosis treatment is not simply to improve a bone-density score. It is to prevent fractures.

Hip fractures, spinal fractures and other fragility fractures can affect mobility, independence and quality of life. Fortunately, effective osteoporosis treatment can substantially reduce the risk of these fractures. For people at high fracture risk, prevention usually involves several measures working together:

• Osteoporosis medication
• Adequate calcium and vitamin D
• Weight-bearing and muscle-strengthening exercise
• Balance training and fall prevention
• Treatment of medical conditions contributing to bone loss
• Prompt treatment after a first fragility fracture

The correct strategy depends on how likely a person is to fracture and whether a fracture has already occurred. For a broader explanation of diagnosis and available therapies, see our main guide to Osteoporosis Treatment.

How Does Osteoporosis Treatment Prevent Fractures?

Osteoporosis weakens the internal structure of bone, making it more likely to break under forces that healthy bone would normally tolerate.

How Much Can Osteoporosis Treatment Reduce Fractures?

The amount of protection varies between medicines and patient groups. According to the International Osteoporosis Foundation, approved osteoporosis medicines can reduce fracture risk substantially, with some treatments reducing:

• Vertebral fracture risk by approximately 30% to 70%
• Hip fracture risk by up to around 40%
• Non-vertebral fracture risk by approximately 15% to 20%

The First Step: Find Out How High Your Fracture Risk Is

Not everyone with low bone density has the same likelihood of breaking a bone. Doctors may consider:

• Bone mineral density from a DXA scan
• Previous fragility fractures
• Age
• Family history of hip fracture
• Long-term steroid treatment
• Smoking
• Alcohol use
• Body weight
• Falls history
• Other conditions that weaken bone

A fracture-risk tool such as FRAX may also be used to estimate future fracture probability. Patients can then broadly be classified as having:

• Lower fracture risk
• High fracture risk
• Very high fracture risk

Why a Previous Fracture Changes Everything

A fragility fracture is one of the strongest indicators that another fracture may occur. A fragility fracture is typically caused by relatively low trauma, such as a fall from standing height. Common sites include:

• Hip
• Spine
• Wrist
• Upper arm

After one fracture, the risk of another fracture is particularly high during the period soon afterward. This is sometimes described as imminent fracture risk. Current osteoporosis guidance therefore recommends starting appropriate treatment promptly after a fragility fracture rather than waiting years for another event. The first fracture should ideally be the point at which prevention of the second fracture begins.

1. Bisphosphonates to Prevent Osteoporosis Fractures

Bisphosphonates are among the most widely used treatments for people at high fracture risk. They reduce bone breakdown and help maintain bone strength. Common options include:

• Alendronate
• Risedronate
• Zoledronic acid
• Ibandronate in selected situations

Current osteoporosis guidelines commonly recommend oral alendronate or risedronate, or intravenous zoledronate, as first-line treatments for many people at increased fracture risk.

Which Fractures Can Bisphosphonates Prevent?

Alendronate, risedronate and zoledronic acid have evidence for reducing:

• Vertebral fractures
• Non-vertebral fractures
• Hip fractures in appropriate high-risk populations

Why Missing or Stopping Denosumab Can Increase Fracture Risk

The effects of denosumab wear off relatively quickly if injections are not continued on schedule. If treatment is stopped without appropriate follow-on therapy:

• Bone turnover can increase rapidly
• Bone density can fall
• Vertebral fracture risk can increase
• Multiple vertebral fractures can occasionally occur

2. Bone-Building Treatment for Very High Fracture Risk

Some patients are at such high risk that simply slowing further bone loss may not be the preferred first strategy. This group may include people with:

• Multiple vertebral fractures
• A recent vertebral fracture
• Very low bone density
• A fracture despite osteoporosis treatment
• Several major fracture-risk factors occurring together

3. Romosozumab

Romosozumab works by both:

• Increasing bone formation
• Reducing bone breakdown

It can reduce vertebral, hip and non-vertebral fractures in appropriately selected postmenopausal women at very high fracture risk. It is generally used for approximately 12 months before transitioning to an antiresorptive treatment. Romosozumab is not suitable for every patient. Cardiovascular history needs to be considered, particularly previous heart attack or stroke.

4. Calcium: Necessary but Not Enough Alone

Calcium is essential for normal bone structure. People with osteoporosis should have adequate calcium intake, preferably from food when possible. Sources can include:

• Milk
• Yoghurt
• Cheese
• Calcium-fortified products
• Other calcium-rich foods appropriate to the person's diet

Supplements may be needed when dietary intake is insufficient. However: Calcium alone is not adequate fracture-prevention treatment for someone at high risk of osteoporotic fractures. It should support evidence-based osteoporosis therapy rather than replace it.

5. Vitamin D

Vitamin D helps the body absorb calcium and supports normal bone mineralisation. Vitamin D deficiency should be corrected, particularly before or during osteoporosis treatment. Supplementation may be needed in people who:

• Have documented deficiency
• Have limited sunlight exposure
• Are housebound
• Have poor dietary intake
• Have conditions causing malabsorption

6. Exercise to Prevent Osteoporosis Fractures

Exercise protects against fractures in two ways. First, mechanical loading supports bone health. Second, stronger muscles and better balance reduce the chance of falling. Current osteoporosis guidance recommends combining:

• Weight-bearing exercise
• Muscle-strengthening exercise
• Balance training when fall risk is present

Possible activities include:

• Walking
• Stair climbing
• Resistance-band exercises
• Weight training
• Balance exercises

Can Exercise Cause a Fracture if Osteoporosis Is Severe?

Potentially, if unsuitable exercises are performed with very fragile bones. This does not mean people with osteoporosis should avoid exercise. Instead, exercise should be selected appropriately. People with vertebral fractures may need to avoid or modify activities involving:

• Forceful repeated forward spinal bending
• Sudden twisting under load
• High-impact activity if fracture risk is very high

7. Preventing Falls

Many osteoporosis fractures occur after a fall. Fall prevention is therefore a genuine osteoporosis treatment—not simply a general safety recommendation. Doctors may review:

• Balance
• Leg strength
• Vision
• Blood pressure
• Footwear
• Mobility
• Medicines that cause dizziness or sedation

Reducing Falls at Home

Useful changes may include:

• Removing loose rugs
• Improving lighting
• Keeping stairs and walkways clear
• Installing handrails where necessary
• Using non-slip surfaces
• Keeping frequently used items within easy reach

8. Maintain Muscle Strength

Loss of muscle mass and strength with age can increase fracture risk even when bone density does not change. Strong muscles help a person:

• Maintain balance
• Recover after stumbling
• Walk more confidently
• Remain physically independent

9. Stop Smoking and Avoid Excess Alcohol

Smoking is associated with poorer bone health and increased fracture risk. Heavy alcohol use can also:

• Weaken bone
• Interfere with nutrition
• Increase falls

10. Treat the Cause of Secondary Osteoporosis

Medication may not work as well as expected if another untreated condition continues weakening bone. Possible secondary causes include:

• Vitamin D deficiency
• Hyperthyroidism
• Hyperparathyroidism
• Coeliac disease or malabsorption
• Low sex hormone levels
• Long-term glucocorticoid treatment
• Certain cancer treatments
• Some chronic inflammatory diseases

What Is Secondary Fracture Prevention?

Secondary fracture prevention means preventing another fracture after someone has already broken a bone because of osteoporosis. This is one of the highest-priority situations in osteoporosis care. The treatment plan may include:

• Bone-density and fracture-risk assessment
• Prompt osteoporosis medication
• Investigation for secondary causes
• Calcium and vitamin D assessment
• Falls assessment
• Exercise and rehabilitation
• Long-term monitoring

What Is a Fracture Liaison Service?

A Fracture Liaison Service (FLS) is a coordinated programme designed to identify people who have suffered a fragility fracture and make sure the underlying osteoporosis is investigated and treated. The aim is simple: Do not repair the first broken bone and then miss the opportunity to prevent the next one.

An FLS may coordinate:

• Fracture-risk assessment
• DXA scanning
• Blood tests
• Osteoporosis medication
• Falls assessment
• Follow-up

A Practical Fracture-Prevention Plan

Common Mistakes That Can Increase Fracture Risk

• Assuming calcium alone is enough to treat high-risk osteoporosis
• Ignoring a wrist or spinal fragility fracture because it was not a hip fracture
• Waiting for another fracture before starting treatment
• Stopping denosumab without follow-on therapy
• Stopping osteoporosis medicine because bone density has improved
• Ignoring balance and falls
• Performing unsuitable high-risk exercises with severe spinal osteoporosis
• Failing to investigate secondary causes of repeated fractures

The Bottom Line

The main goal of osteoporosis treatment is to prevent fractures—not simply to increase bone density. People at high fracture risk generally benefit from osteoporosis medication. Bisphosphonates such as alendronate, risedronate and zoledronic acid are widely used first-line options, while denosumab is another effective antiresorptive treatment when appropriate.

People at very high fracture risk, especially those with recent or multiple vertebral fractures, may benefit from specialist assessment and an anabolic-first approach using medicines such as teriparatide, abaloparatide or romosozumab. These treatments are usually followed by antiresorptive therapy to preserve the bone gains.

After a fragility fracture, treatment should begin promptly because the likelihood of another fracture is particularly high soon after the first one. Medication works best as part of a broader strategy that also includes adequate calcium and vitamin D, appropriate weight-bearing and strengthening exercise, fall prevention, treatment of secondary causes and regular follow-up.

Most importantly: The best fracture-prevention plan strengthens the bone, reduces the chance of falling and acts quickly after the first fracture—because preventing the next fracture is one of the most important goals of osteoporosis care.
