Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The analysis of the alignment of the foot is fundamental in the management of pathologies of the foot and ankle. The advent of 3D imaging under load (Scanner Cone Beam), less radiant and more precise, requires the development and evaluation of new measurement tools.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ankel surgery group

Adult patients for which a Cone Beam under load is prescribed for a preoperative assessment of a foot or ankle surgery or for a follow-up consultation.

3D Imaging FAO measurement and Clinical evaluation of the hindfoot alignment

Intervention Type DIAGNOSTIC_TEST

The Cone Beam under load is used for the diagnosis and monitoring of the foot and ankle. It has a CE marking for this purpose.

The images obtained by the Cone Beam under load (Ped Cat) will be analysed using the TALAS mathematical algorithm tool to measure the FAO.

The internal software of the Cone Beam under load will also be used to obtain a "radiographic" image corresponding to a 2D projection on which the tibio-calcaneal angle can be measured.

control foot group

Adult patients for which a Cone Beam under load is prescribed for a preoperative assessment of a foot or ankle surgery or for a follow-up consultation.

Will be retained only results of normal aligment FAO

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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).
