Evaluating combined Adductoplasty™ and Lapiplasty® procedures for foot correction

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, multicenter study aims to assess the outcomes of the Adductoplasty™ Procedure in conjunction with the Lapiplasty® Procedure for patients suffering from metatarsus adductus and hallux valgus. The study will involve up to 80 participants aged 14 and older, who will be treated across 13 clinical sites. Researchers will evaluate quality of life and pain scores post-surgery, as well as the effectiveness of the combined procedures in correcting and maintaining proper anatomical alignment of the metatarsals and hallux. Participants will be monitored for adherence to post-operative care and scheduled follow-up visits.
