For Switzerland, approximately 82,000 new fragility fractures were estimated for 2019 — on average about one every six to seven minutes. With an ageing population, this number is expected to rise further; projections suggest close to 113,000 fractures by 2034. These are modelled estimates: Switzerland does not yet have a comprehensive national fragility fracture registry.
An osteoporotic vertebral fracture is not merely an isolated injury. It is a warning sign: the acute fracture must be assessed and treated, while the risk of further fractures should be systematically evaluated and reduced.
Why a vertebral fracture is a warning sign
The vertebral bodies of the thoracic and lumbar spine bear a substantial proportion of body weight and contain a high proportion of trabecular bone — the fine internal structure that can be particularly impaired by osteoporosis. This makes vertebral fractures among the most common osteoporotic fractures.
They often arise without a significant injury — while lifting a shopping bag, bending forward, or seemingly from nowhere. Not every vertebral fracture causes immediate pain; some become apparent later through height loss or a gradually developing kyphosis.
A widely cited study illustrates the subsequent fracture risk: in an analysis of postmenopausal women with osteoporosis, nearly one in five sustained a further radiologically confirmed vertebral fracture within a year of an incident vertebral fracture.[3] The exact magnitude of individual risk varies, and not every subsequent fracture causes symptoms. The key message: a first fracture is an important warning sign and should prompt thorough assessment and treatment.
Two tasks after a vertebral fracture
- Treat the acute fracture.
- Reduce the risk of further fractures.
Both belong together. A technically successful treatment of a single vertebra does not address the underlying skeletal disease.
The second task includes assessment of individual fracture risk, bone densitometry, investigation of potential secondary causes, and risk-adapted medical therapy. Equally important are adequate calcium and vitamin D intake with supplementation where needed, physical activity, strength and balance training, and fall prevention. This is typically coordinated with the GP, rheumatology, endocrinology, or specialist osteoporosis services.
A fracture is not a static event
Particularly important — and underemphasised in many standard texts — is the dynamic nature of these fractures: some vertebral bodies continue to collapse over days and weeks, or become progressively unstable. An initially stable situation can change and influence the treatment strategy.
Persistent or worsening symptoms therefore warrant reassessment. In particular, increasing pain, declining mobility, new height loss, or a change in posture should prompt re-evaluation of the imaging findings.
When to seek prompt medical review: Weakness, new-onset numbness, or bladder or bowel dysfunction may indicate spinal cord or nerve involvement — this is an emergency (call 144 or go to the nearest emergency department).
How treatment of the fracture is determined
Whether a vertebral fracture is managed conservatively or surgically does not depend on a single number but on a comprehensive assessment: fracture type, progression, symptoms, mobility, bone quality, and general health.
Two structured tools provide guidance: the OF Classification — which grades the fracture morphology and extent of vertebral body damage on imaging — and the supplementary OF Score, which incorporates clinical factors. Both help to structure the decision transparently, but do not replace individual clinical judgement.
The specific treatment options — from conservative management to minimally invasive cement augmentation to instrumented stabilisation — are described in detail on the Vertebral Fracture page.
My approach
Osteoporotic vertebral fractures are one of my clinical and scientific areas of focus. In a retrospective ten-year analysis at a Swiss university hospital, my team and I evaluated 8,307 acute vertebral fractures of various aetiologies with respect to epidemiology, treatment patterns, and complications.[6] This scientific experience informs my clinical practice: a careful assessment of the findings, a transparent recommendation, and — where appropriate — explicitly also a recommendation against intervention.
Questions about your situation?
If a vertebral fracture has been identified or you are unsure whether your osteoporosis is adequately treated, a thorough assessment provides clarity.
