Brief Summary

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

The aim of the study is to investigate the effect of subtalar extra-articular calcaneo-stop screw on the proprioceptive and nociceptive pathways of the ankle before and after implantation. The hypothesis of the study is that an increased number of receptors related to proprioception will be detected in the sinus tarsi.

Study Groups

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

Control Group

Control group are patients that will insert the calcaneo-stop screw (age between 10 and 14 years old).

Histological Analysis

Intervention Type OTHER

For the study, a minimal part of the periarticular tissue, specifically the sinus tarsi juxta-articular fatty tissue, that is normally dissected and discarded during the surgical operation of insertion and removal of the calcaneo-stop screw, will be analyzed
