Evaluation of a New Tool for Measuring Hindfoot Alignment Under Load and in 3D.
France125 participantsStarted 2018-02-13
Plain-language summary
The automated TALAS measurement tool, working with the Cone Beam 3D scanner under load, provides a reproducible measurement of the Foot Ankle Offset (FAO). It is possible to determine an average value and the standard deviation of FAO in the relevant population. And to differentiate significantly the populations with a neutral alignment, varus or valgus.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patient selected for a preoperative assessment in foot or ankle surgery, or patient seen in follow-up consultation for which a Cone Beam under load is prescribed
* Patient having been informed of this study and having given their consent
* Patient over 18 years old
* Unprotected adult
Exclusion Criteria:
* Patient with a contraindication to the Cone Beam under load
* Patient refusing to participate in this study
* Non-plantigrade foot under load (impossibility of simultaneously resting M1, M5 and Calcaneus on the ground)
* Patient who has already participated in the 3D HAM study (patients who would have participated in the study during the preoperative consultation for which another Cone Beam would be prescribed during the follow-up consultation. These patients would not be able to participate again in this study).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
