Study summary

Recent advances in personalized 3D modeling make it possible to consider personalized hand modeling based on cone-beam CT. The goal is to develop a personalized 3D modeling tool for use in routine clinical practice that reduces both the radiation dose to which patients are currently exposed during CT scans and the time required to process CT data (segmentation). the main, objective of the study is to compare the quality of 3D hand modeling based on cone-beam CT with the gold standard of computed tomography.

This prospective, single-center, interventional study will include 6 healthy volunteers.

Yes

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • no clinical symptoms suggestive of a wrist ligament injury (e.g., pain, instability)
  • no to undergoing a CBCT scan (e.g., pregnancy, history of to radiation).
  • Enrolled in or eligible for a French social security plan.
  • Signing of an form indicating that the subject understands the purpose and procedures required by the study and agrees to participate in the study and comply with the requirements and restrictions inherent to this study

Exclusion criteria

Exclusion Criteria:

  • Pregnant women and breastfeeding mothers
  • Persons deprived of their liberty by a judicial or administrative decision; persons undergoing involuntary psychiatric treatment; persons admitted to a health or social care facility for purposes other than research
  • Adults subject to a legal protection measure (judicial protection, guardianship, or conservatorship) or who are unable to give consent
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jun 2026; primary completion for Oct 2026, 4 months later.

Of 17 interventional studies with no phase under Wrist Injuries, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 58. This study's planned 4 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 8, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
