- Design
- Retrospective national claims cohort
- Population
- 467,721 US women aged 50 and over with an incident clinical fracture
- Primary outcome
- Subsequent fracture at least 90 days after the index fracture
- Effect
- 24-month refracture 19.4% (spine 27.8%, pelvis 24.2%); treatment started in 17.5%
A US claims cohort identified 467,721 women aged 50 and over with a new clinical fracture between 2012 and 2021, median age 76.
Within 24 months, 19.4% had another fracture. Risk was highest after a vertebral fracture (27.8%) and a pelvic fracture (24.2%), and rose with age and with a prior osteoporosis diagnosis. Yet only 17.5% started osteoporosis treatment within two years, and most who did so started within six months.
The first fracture is the clearest warning of the next, and the window is short. Much of this care falls to physicians who see the patient on a medical ward or in clinic after the orthopaedic episode, not the fracture surgeon.
In India, where vitamin D deficiency is common and bone density scanning is not always accessible, a fragility fracture in an older woman can itself justify starting assessment and treatment.
- Treat any low-trauma fracture after 50 as a diagnosis of osteoporosis until proven otherwise
- Start or arrange osteoporosis assessment before discharge, not at a later review
- Check calcium, vitamin D, renal function and dental status before starting a bisphosphonate
- Prioritise vertebral and pelvic fractures, which carried the highest short-term risk
- Assess falls risk and medicines that cause falls at the same time
Why it matters
The commonest missed opportunity in fracture care is the treatment that never starts after the first one.
Don't overread it
Claims data may miss treatment paid for outside insurance, so the true treatment rate may be slightly higher.
The statistics, in plain English
These are observed rates from routine data, not a trial. The 19.4% two-year refracture risk is a weighted cumulative incidence across nearly half a million women, so it is a reasonable picture of routine practice in the US.
