Brief Summary:

A novel methodology was recently developed and validated by the applicants to compute bone strength at the distal radius and tibia using second-generation HR-pQCT reconstructions. The methodology is expected to improve significantly the assessment of bone fracture risk in idiopathic and secondary osteoporosis, but no reference data and no reproducibility data are available.

The objective of the study is the determination of the sex- and age-specific distributions of accurate distal radius and tibia strength assessed by HR-pQCT in the Swiss population.

Osteoporosis Diagnoses Disease Fracture Bone Strength

Detailed Description:

Objective: De novo determination of sex- and age-specific reference intervals for vBMD, bone architecture, and bone strength assessed by 3D HR-pQCT with a resolution of 61 µm (Xtreme CT II, Scanco Medical, Brütisellen, Switzerland) in the Swiss population.

Design: Population-based, age- and sex-stratified, cross-sectional study in a single centre.

Study Size: For the main part, 480 valid data sets will be needed for two age reference intervals for both women and men. The number of double/triple stack scans will be between 1 and 3 depending on graded motion artefacts.

Among the 120 participants of each reference interval, 21 will be needed to assess reproducibility. For these volunteers, the number of double/triple stack scans will be equal to 3.

Project Assessments, Procedures: participant demographics and physical activity will be obtained and the validated Swiss FRAX questionnaire will be filled to determine the epidemiology-based 10-year fracture risk. Grip strength will be measured. A DXA measurement at the hip will be done according to the standard protocol of the Universitätspoliklinik für Osteoporose. For participants at elevated vertebral fracture risk, lateral and antero-posterior DXA of the spine will be added for vertebral fracture assessment (VFA) and spine areal bone mineral density (aBMD). The HR-pQCT examination per se consists then of up to 3 repeated double stack scans at the distal radius and triple stack scans at the distal tibia.

  • Implant or a fracture at the DXA and HR-pQCT measurement sites
  • Inability to keep the extremities still for the few minutes of an HR-pQCT examination (e.g. Parkinson disease or spastic syndrome)
  • History of low trauma fracture
  • Known pregnancy or lactating women
  • History of hysterectomy and/or ovariectomy
  • Known metabolic bone disorders, such as osteogenesis imperfecta, Paget's disease or sclerosteosis (osteopenia or idiopathic osteoporosis are not exclusion criteria)
