About the research

The goal of this observational study is to learn about the incidence and risk factors of postoperative chronic pain in adult patients who have undergone Hallux Valgus surgery (between january 2021 and december 2024). This will be assesed through scales and medical records information.

The main questions to be answered are:

• How many patients who have undergone Hallux Valgus surgery are experiencing postoperative chronic pain.
• What factors are there present in those who do experience chronic pain after surgery.

After accepting the informed consent, participants will be asked to answer a Brief Pain Inventory Scale and a Risk Factor Questionnaire for Postoperative Chronic Pain.
