Osteoporosis After a Fracture

Q: I broke a bone from a fall that shouldn't have broken it. Does that mean I have osteoporosis?

Not necessarily, but it is exactly the kind of event (called a fragility fracture) that guidelines like the UK's NOGG 2024 recommend acting on. A fracture from a fall from standing height or less, or from a minor bump, is a recognised trigger for a fracture risk assessment. Only a bone density (DEXA) scan and your doctor's assessment can tell you whether osteoporosis or low bone density is involved.

Q: How soon after a fracture should I get a bone density scan?

There is no single universal timeframe, but the NOGG 2024 guideline is clear that risk of a further fracture is highest in the period immediately after the first one, and recommends repeating a fracture risk assessment after any new fracture, regardless of when it occurs. In practice this means it's worth raising with your GP or surgical team as soon as you are able, rather than waiting.

A broken bone from a fall or a minor bump is often the first sign worth acting on — not just healing from.

Doctors call it a fragility fracture: a break caused by a fall from standing height or less, or a bump that shouldn’t really break a healthy bone. A wrist, hip, shoulder or spine fracture from something minor like that is not just an injury to heal from — it is one of the clearest signals there is that it may be worth checking the strength of the bone underneath it.

This page is not about frightening anyone. Most people who break a bone this way are never told this is worth following up on, and that gap is exactly what a fracture liaison approach, used in many health systems, exists to close. This page covers what getting checked involves, what the evidence says about calcium, vitamin D and exercise, and how to reduce the chance of a second fall in the first place.

Why a first fracture matters so much

The UK's National Osteoporosis Guideline Group (NOGG) puts it plainly in its 2024 clinical guideline: the risk of a further fracture is at its highest in the period immediately after the first one, and it recommends repeating a fracture risk assessment after any new fracture, regardless of when it occurs. It also recommends starting treatment promptly where it's needed, precisely because that early window matters so much, and that people have access to a coordinated, multidisciplinary Fracture Liaison Service where one exists. If your hospital or clinic has one, it's worth asking to be referred rather than assuming someone will raise it with you.

Getting checked: what a bone density scan involves

The Royal Osteoporosis Society notes that people over 40 who have broken a bone easily may be referred for a fracture risk assessment, and in Australia, healthdirect lists a fragility fracture, along with age (over 50 for women, over 60 for men), family history of fracture, smoking, low vitamin D or calcium, low body weight, recurrent falls and reduced mobility, as reasons a doctor might request one.

The scan itself, a DEXA or DXA scan (dual energy x-ray absorptiometry), is a low-dose x-ray. You lie on a padded table for around 20 minutes while a scanning arm passes over your body; it doesn't hurt. The result is a T-score, compared against a young healthy adult's bone density:

−1 or above: normal bone density
Between −1 and −2.5: lower than normal (osteopenia)
−2.5 or below: osteoporosis

A risk-assessment tool such as FRAX is often used alongside the scan to estimate your individual 10-year fracture risk, combining the scan result with things like age, weight, and fracture and family history.

Calcium and vitamin D: food first

The Bone Health & Osteoporosis Foundation's guidance is to aim for the recommended daily amount of calcium from food first, and supplement only to make up any shortfall:

Calcium: 1,000mg/day for women 50 and under and men 70 and under; 1,200mg/day for women over 50 and men over 70
Vitamin D: 400–800 IU/day under 50; 800–1,000 IU/day for 50 and over

Individual needs vary, and this page deliberately doesn't recommend specific supplement products or doses: a simple blood test can check whether your vitamin D level is actually low before you start anything, and your GP can advise what's right for you.

Exercise: what helps, and what to be careful with after a fracture

Mayo Clinic's guidance on exercising with osteoporosis highlights a few categories that genuinely help bone and fall-risk over time:

Strength training: free weights, resistance bands, or your own bodyweight
Weight-bearing aerobic activity: walking, dancing, low-impact aerobics, stair climbing, gardening
Balance and stability work: standing on one leg, tai chi — genuinely useful for reducing fall risk, not just bone strength
Gentle flexibility work after warming up

The same guidance is specific about what to be cautious with, especially with lower bone density: high-impact movements like jumping, running or jogging, and bending forward or twisting sharply at the waist (toe touches, sit-ups, some golf swings and yoga poses), because these movements are linked to a higher risk of spinal fracture in weakened bone.

If you're still in the early weeks after a fracture, none of this overrides what your own surgical or physiotherapy team has told you — check with them before starting or changing anything.

Fall-proofing your home

The single most effective way to prevent a second fracture is to prevent the next fall. The US CDC's STEADI home safety checklist groups common hazards by room:

Stairs: broken or uneven steps, loose or torn stair carpet, loose or missing handrails (ideally on both sides)
Floors: clutter such as papers, shoes and books; throw rugs without a non-slip backing
Kitchen: frequently-used items stored on high shelves; unstable step stools
Bedroom: hard-to-reach bedside lighting; a dark path between bed and bathroom
Bathroom: slippery tub or shower floors; missing grab bars near the tub, shower or toilet

Worth mentioning to your GP?

Tick anything that applies to you. These are among the factors used in fracture-risk tools like FRAX — this is not a diagnosis or a risk score, just a prompt for a conversation.

Broke a bone from a fall from standing height or less, or a minor bump Woman over 50, or man over 60 Parent had a hip fracture Long-term steroid (corticosteroid) medication Smoker, or more than moderate alcohol intake More than one fall in the past year Low body weight, or a condition such as rheumatoid arthritis

Tick anything that applies — nothing is saved or sent anywhere, it's just to help you see the pattern before you see your doctor.

Frequently asked questions

Not necessarily, but it is exactly the kind of event (a fragility fracture) that guidelines like NOGG 2024 recommend acting on. A fracture from a fall from standing height or less, or a minor bump, is a recognised trigger for a fracture risk assessment. Only a bone density (DEXA) scan and your doctor's assessment can tell you whether osteoporosis or low bone density is actually involved.

Do I need calcium and vitamin D supplements after a fracture?

Not automatically. The Bone Health & Osteoporosis Foundation recommends getting calcium from food first and only supplementing to cover any shortfall, with adults generally needing 1,000–1,200mg of calcium and 400–1,000 IU of vitamin D daily depending on age and sex. Ask your doctor whether a blood test to check your vitamin D level is appropriate before starting any supplement.
