3D scanner could revolutionize foot alignment diagnosis
NCT ID NCT04134962
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study evaluates a new automated tool called TALAS that uses 3D scans taken while standing to measure hindfoot alignment. Researchers aim to see if it can reliably classify foot alignment as neutral, varus, or valgus. The study involves adults already scheduled for foot or ankle surgery or follow-up. If proven accurate, this tool could help doctors better diagnose and plan treatments for foot and ankle problems.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 3D imaging with Cone Beam under load and TALAS algorithm
- What this could lead to
- If successful, this tool could provide a more reliable and automated way to measure hindfoot alignment, potentially improving surgical planning and outcomes for foot and ankle conditions.
- What could go wrong
- This is an early-stage diagnostic study focused on measurement accuracy, not a treatment. The tool may not prove significantly better than existing methods, and results may not apply to all patients.

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).
