Risk profile

What OCTON knew before the scan
Risk
64
high
Tier
high
Wrist fracture from low-impact fall on Tuesday. Otherwise independent. Coffee-machine difficulty for 6 months (early MoCA 24/30, executive subscale drop).
Contributing factors
  • Fragility fracture at distal radius (low-impact)+26
  • Hip DXA T-score −2.8 (osteoporosis)+18
  • Age 71 + post-menopausal+10
  • MoCA 24/30 (mild cognitive concern)+6
  • Sub-cortical WM hyperintensities (Fazekas 2)+4
Narrative

Frances has an obvious bone problem and a quieter brain problem. The fragility fracture is a sentinel event — Z-score-validated. The cognitive softness + Fazekas 2 SVD raises mixed dementia risk; early lifestyle + vascular-risk modification can slow progression by ~40%.

How to actually realise the gain

These are the specific levers OCTON puts on your plan — each one comes with the expected impact below.

drug
Zoledronic acid 5 mg IV annual × 3-5 yrs
Halves re-fracture risk
drug
Calcium 1200 mg + Vit D 1000-2000 IU/day
Bone mineralisation + falls reduction (vit D)
scan
DXA every 2 yrs + MoCA annual + falls assessment
Tracks therapy response + cognition
diet
Mediterranean + 1.2 g/kg protein + dairy
Sarcopenia + bone + brain support
exercise
Resistance 2×/wk + balance training (Tai Chi)
Builds bone density + halves fall risk
lifestyle
Home OT visit + remove rugs/lighting/grab bars
Eliminates avoidable fall triggers

Lumbar L1-L4 T-score −2.4. Total hip T-score −2.8 (femoral neck −2.9). FRAX 10-year major osteoporotic fracture probability 24%, hip fracture 9.4%. Osteoporosis confirmed by WHO criteria.

Findings
  • Hip T-score −2.8 (osteoporosis) · Total hip
  • Femoral neck T-score −2.9 · Right femoral neck
  • L1-L4 T-score −2.4 (osteopenia border-osteoporosis) · Lumbar spine
  • FRAX major fracture risk 24% · Whole-skeleton
Differential diagnosis
  • Primary post-menopausal osteoporosis80%
  • Secondary causes (vit D deficiency, hyperparathyroidism)15%
  • Steroid-induced bone loss (no exposure documented)5%
Recommended actions
  • ▸Start zoledronic acid 5 mg IV annual × 3 yrs (FLEX trial) OR oral alendronate 70 mg weekly
  • ▸Calcium 1000-1200 mg/day, vitamin D 800–2000 IU/day
  • ▸Vitamin D 25(OH) + PTH + calcium + TSH + 24-hr urinary calcium to rule out secondary causes
  • ▸Falls-prevention programme; home OT assessment
Caveats
  • Repeat DXA at 2 years on therapy; T-score improvement is gradual.
  • Cervical SVD findings deserve separate cognition workup — see memory clinic referral.

What changed

The early-detection win

Frances came in for an ED-aftercare visit for her wrist fracture. The cubicle picked up the second story her primary problem was hiding: the same vascular risk that drives osteoporosis can drive vascular dementia. One sentinel event, two referral pathways activated. Three years later: zero new fractures, MoCA stable at 25/30, BP optimised, vitamin D 48 ng/mL. The 'wrist fracture' visit added 6 quality-adjusted life-years.
