Metatarsus Adductus

Metatarsus adductus is a common foot condition seen in newborns and infants. Metatarsus adductus is found in about 1% of all newborns. It is usually noticed, as the toes and forefoot are pointed inward. The appearance of the sole of the foot has been described as a "bean shape."

What Causes Metatarsus Adductus?

Metatarsus adductus is one of the so-called "packaging problems" thought to be due to the position of the child in the womb. Other packaging problems include:

• Torticollis
• Clubfoot
• Hip dysplasia

What Is the Treatment for Metatarsus Adductus?

Some doctors recommend stretching, special footwear, or physical therapy. The truth is, 90 to 95% of children with metatarsus adductus will spontaneously resolve the deformity regardless of treatment, including no treatment whatsoever.

In cases of a rigid deformity (meaning the foot cannot be stretched to a normal position), cast treatment will be initiated. Casts are molded to stretch the foot into a normal position. This treatment should be initiated in the first 6 months of life. If casting does not improve the foot position, a surgery may be recommended. Surgery is usually delayed until after age 3, and only when cast treatment fails to improve the foot.
