What is prehallux?

Prehallux is a small, accessory bone or cartilage that can be found in the foot, typically located in the area of the first metatarsal, near the base of the big toe. It is considered a developmental variation and is not present in everyone. While it may not cause any symptoms or issues, in some cases, it can lead to discomfort or complications, particularly if it is involved in foot mechanics or shoe fit. Its presence is often identified through imaging studies.
