Which of the following is not an indication of a bunion?

Hallux varus is characterized by an inward deviation of the big toe away from the second toe, and it is not considered an indication of a bunion. In sharp contrast, a bunion, or hallux valgus (HAV), involves an outward deviation of the big toe towards the second toe, often leading to the protrusion seen on the medial side of the foot.

Bunion conditions typically exhibit hallux valgus, medial prominence protrusion, and can even lead to joint destruction due to the continuous pressure and misalignment associated with the deformity. Thus, while hallux valgus directly describes the bunion condition, the medial prominence is a physical manifestation, and joint destruction can occur as the bunion progresses. In summary, since hallux varus does not align with the characteristics associated with a bunion, it is the correct choice for what is not an indication of a bunion.
