Summary

This study looks at whether surgery to correct hallux valgus (a bunion) can reduce shoe size and change the shape of the front of the foot. Researchers will use 3D surface scanning to measure foot dimensions before surgery and again at 6 months after. The trial involves 100 adults undergoing a specific type of corrective surgery (Scarf + P1 osteotomy). The goal is to see if the surgery leads to a meaningful reduction in shoe size, which could improve how shoes fit.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Surgical correction of hallux valgus via Scarf + P1 osteotomy
What this could lead to: If successful, this could show that hallux valgus surgery not only corrects the toe but also leads to a measurable reduction in shoe size, potentially improving comfort and fit.
What could go wrong: This is a small, single-center study without a comparison group, so results may not apply broadly. The expected shoe size change is small (at least 0.5 Paris points), and individual outcomes may vary.
