Osteogenesis Imperfecta Fracture Risk and Bisphosphonate Response

Calculates fracture risk in osteogenesis imperfecta using Sillence classification type, annual fracture rate, DXA Z-score, and pamidronate/zoledronic acid treatment response monitoring.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates fracture risk in osteogenesis imperfecta using Sillence classification type, annual fracture rate, DXA Z-score, and pamidronate/zoledronic acid treatment response monitoring

Each component has a specific meaning:

  • Sillence classification type — The sillence classification type recorded for the scenario being assessed.
  • Annual fracture rate — The annual fracture rate recorded for the scenario being assessed.
  • DXA Z-score — The dxa z-score recorded for the scenario being assessed.
  • Pamidronate/zoledronic acid treatment response monitoring — The pamidronate/zoledronic acid treatment response monitoring recorded for the scenario being assessed.

Note: Interpret the oi fracture risk result against the thresholds and context described above.

How to Use

Enter the Sillence classification type, annual fracture rate, DXA Z-score, pamidronate/zoledronic acid treatment response monitoring for the scenario you are assessing. Calculates fracture risk in osteogenesis imperfecta using Sillence classification type, annual fracture rate, DXA Z-score, and pamidronate/zoledronic acid treatment response monitoring. Use the oi fracture risk result to inform your calculation.
