What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study uses two special scanners (HR-pQCT and pQCT) to take detailed pictures of bone and muscle in 1,000 people with conditions that raise the risk of bone loss, like osteoporosis, arthritis, or kidney disease. The goal is to see if these scanners can spot tiny changes in bone structure that current methods miss, which could help doctors better predict and prevent fractures. Participants will have their bones scanned and compared to a healthy control group.

Inclusion Criteria: For the patients: Women or men treated at the Saint-Etienne University Hospital and presenting an osteoporotic risk with one of the following associated pathologies: * Osteoporosis defined by: History of a documented brittle bone fracture * Bone fragility: Patient with indication for bone densitometry but no history of fracture * Inflammatory joint disease: * Rheumatoid arthritis * Spondyloarthritis * Chronic kidney disease * Endocrinopathies: * Primary hyperparathyroidism * Constitutional thinness * Anorexia nervosa * Obesity (BMI \>30) * Sarcopenia * Neuropathies - Parkinson's disease For the controls: Acute episode of spinal or radiculalgia (less than one month old) with corticosteroid treatment of less than 1 month Signature of written consent Exclusion Criteria: * No sign written consent For the controls: * Medications inducing bone loss: * anti-aromasin or GnRH agonist for at least 6 months, * corticosteroids (dose ≥ 5 mg/d for 6 months) * anti-epileptic drugs: carbamazepine, phenobarbital, phenytoin, primidone, valproic acid for at least 6 months) * History of fracture due to bone fragility * Taking bone-targeting medication (biphosphonate, teriparatide, strontium ranelate)
