Which of the following is true of metatarsus adductus?

Mild flexible metatarsus adductus is characterized by the inward bending of the foot at the metatarsal level. One of the key aspects of this condition is its tendency to resolve naturally over time, especially when it is mild and the affected feet are flexible. This spontaneous correction typically occurs as the child grows and engages in normal activities that promote healthy foot development. Parents and healthcare providers often monitor the condition rather than pursuing aggressive interventions.

The other options do not align with the typical presentation or management of metatarsus adductus. While more severe cases may require intervention, such as casting or other forms of treatment, mild cases do not generally necessitate such measures. Additionally, metatarsus adductus is distinct from clubfoot, which is a more complex condition involving multiple structures of the foot and ankle. Lastly, the diagnosis of metatarsus adductus usually relies on clinical examination, and X-rays are typically not required unless there are concerns about associated conditions or if the diagnosis is uncertain. Thus, the first statement about mild flexible metatarsus adductus spontaneously correcting is accurate and reflects current understanding of this common pediatric foot deformity.
