Metatarsus Adductus Hallux Valgus Mta3 D

ClinConnect Summary

This clinical trial is studying the effectiveness of a combined surgical approach called Adductoplasty™ and Lapiplasty® to treat two foot conditions: metatarsus adductus (a foot deformity where the front part of the foot turns inward) and hallux valgus (commonly known as a bunion). The goal is to see how well this combined treatment works for patients aged 14 and older who have noticeable symptoms from these conditions. Up to 80 participants will be included from various clinical sites.

To be eligible for the study, participants need to be at least 14 years old, have certain angles in their foot measurements that indicate the severity of their conditions, and be willing to follow post-surgery care instructions. Participants can expect to undergo the combined procedure and will need to attend follow-up visits to track their recovery. It’s important to note that individuals with certain medical conditions or previous surgeries on the affected foot may not qualify for this trial.
