Study summary

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.

What researchers measure

Primary outcomes

  1. The incidence of Chronic Postoperative Pain (CPOP) following Hallux Valgus surgeries

    The main outcome (chronic pain related to Hallux Valgus surgeries) will be assessed through the Brief Pain Inventory scale: * Pain intensity: Moderate (Visual Analog Scale 5 - 7) or severe pain (Visual Analog Scale 8 - 10). * Time: over 3 months. * Pain description: pain is anatomically located where the Hallux Valgus surgery has taken place.

    Time frame: "Day 1" The outcome measure will be recorded on day 1, when the patient has agreed to the informed consent and to answer the questionnaire.
