What is the medical term for a bunion?

The medical term for a bunion is "Hallux valgus," which describes a specific deformity at the base of the big toe. In this condition, the big toe deviates laterally towards the other toes, while the first metatarsal bone shifts medially. This misalignment creates a prominent bump on the side of the foot, which is what is commonly referred to as a bunion.

"Hallux" refers specifically to the big toe, and "valgus" indicates an outward angulation of the toe relative to the foot's midline. The combination of these terms accurately captures the nature of the bunion deformity.

Other terms, such as "talipes," refer to different conditions involving the foot and ankle, specifically deformities related to misalignment of the foot and toes that do not specifically involve a bunion. Therefore, those options do not apply to the bunion condition. Understanding these terms helps to clarify the specifics of foot anatomy and the nature of various deformities encountered in medical contexts.
