Which of the following is true about metatarsus adductus?

• A. This condition is another term for clubfoot.
• B. Mild flexible metatarsus usually spontaneously corrects.
• C. X-rays are usually necessary to diagnose this.
• D. Infants frequently require casting to correct.

Answer: (B)

Metatarsus adductus in newborns is when the front of the foot turns inward due to intrauterine positioning. Most cases are mild and flexible, meaning the foot can be gently moved toward a straight position and tends to straighten on its own over time. Because of this natural tendency, mild flexible metatarsus adductus usually corrects spontaneously without intervention, often within the first year or two of life.

X-rays aren’t typically needed for diagnosis; this condition is diagnosed clinically by exam, noting that the forefoot can be passively corrected. Casting or other aggressive treatments aren’t usually required for mild flexible cases; casting is reserved for rigid or persistent deformities that do not improve on their own. It’s also important to distinguish it from clubfoot, which involves more complex, rigid deformities of the foot and ankle.

So the best statement is that mild flexible metatarsus adductus usually corrects spontaneously.
