Bone Microarchitectural Database Constitution From HR-pQCT Device in Clinical Situation Potentially Associated With Bone Loss (DMPOs)
Bone Microarchitectural Database Constitution From High Resolution Peripheral Quantitative Computed Tomography (HR-pQCT) Device in Clinical Situation Potentially Associated With Bone Loss
Bone fracture occurrence is associated with an increasing of morbidity and mortality. Some factors of fracture occurrence have been highlighted. For example, some diseases or therapy are known to increased risk of bone fracture only in some patients. Accordingly, it is important for clinicians to identify patients at risk for bone fracture. Right now, various tools are available for the clinicians:
- clinical exam,
- bone mineral density assessed by Dual Energy X-ray Absorptiometry (DEXA),
- an algorithm based on interrogation, clinical exam and bone mineral density. However, prediction of bone fracture risk needs to be improved since only 50% of bone fractures can be predicted. DEXA provides information for fracture risk estimation, but it is unable to distinguish cortical part to trabecular part. It also fails to quantify the microstructural properties that influence bone strength. Bone microarchitecture, including the cortical compartment can now be assessed in vivo by the HR-pQCT. This technique allows access to several parameters: on the one hand the volumetric bone mineral density for the whole area measured as well as cortical and trabecular regions, and on the other hand, the thickness and cortical porosity and the number of trabecular, their orientation and distribution.
Thus, the HR-pQCT allows realizing a virtual bone biopsy and provides information on cortical and trabecular bone microarchitecture. This is the only noninvasive way to assess cortical and trabecular bone microarchitecture.

Experimental: Patient group
Measure bone quality and quantity with HR-pQCT, pQCT and DEXA of patient group Patient group is patient with one of the following pathology : Osteoporosis, Bone Fragility, articular inflammatory disease or Endocrine diseases

Xtreme CT® device is a high resolution peripheral quantitative computed tomography (HR-pQCT) used to measure bone density and quantify the bone architecture to 3D at the extremities of the human body. For the study, the device will be used to assess bone density and microarchitecture at the forearm and shin for a systemic effect. In rheumatoid arthritis, bone density and microarchitecture will also be measured at the metacarpophalangeal.
The Lunar Dual Energy X-ray Absorptiometry (DEXA) is a third generation multi-captor DEXA device that allow short duration measurements.
It measures Bone Mineral Density (BMD) at the spine and the femoral neck
Peripheral Quantitative Computed Tomography (pQCT) will be performed and measure bone and muscle parameters.

Experimental: control group
Measure bone quality and quantity with HR-pQCT, pQCT and DEXA of control group.
Patient group is patient with episode of acute back pain or radicular pain

Bone density
Time Frame: day 1

Bone density is a composite outcome measured with three devices HR-pQCT, pQCT and DEXA. Parameters measured with HR-pQCT are : Total volumetric mineral density (mg/ccm HA), Trabecular volumetric mineral density (mg/ccm HA) and Cortical volumetric mineral density (mg/ccm HA). Parameters measured with pQCT are: total bone mineral content (mg), total bone surface (mm2), total bone density (mg/mm3), cortical and trabecular density (mg/mm3), and the bone resistance index (g2/mm). Parameter measured by DEXA is Bone Mineral Density (BMD, g/cm2) |
