Pilot Study Comparing Two Types of Percutaneous Surgery to Correct Adult Hallux Valgus Deformity

What this Trial Is About

This research aims to evaluate two different surgical procedures for correcting hallux valgus, a common foot deformity. The study is a pilot randomized controlled trial focused on adult patients aged 18 to 65 years with specific angles of deformity hallux valgus angle between 20 and 40 degrees and intermetatarsal angle between 10 and 20 degrees. It is designed to compare clinical and functional outcomes of these procedures over time. Participants will be randomly assigned to one of two surgical treatments the SERI osteotomy, which corrects the deformity using Kirschnner wire stabilization, or the percutaneous osteotomy according to Chevron, which uses two screws inserted through small dorsal incisions for stabilization. Both procedures aim to correct the varus deformity of the first metatarsal bone. The study does not use blinding and involves standard surgical techniques. During the study, researchers will assess pain levels using the Visual Analog Score at the start and one year after surgery. They will also measure foot function with the American Orthopaedic Foot and Ankle Society forefoot score at baseline and after one year. Participants will be monitored for clinical-functional outcomes over this period. The total study duration spans several years, starting in February 2022 and ending in December 2026, under the sponsorship of Istituto Ortopedico Rizzoli.
