Metatarsus adductus is thought to be caused by which of the following?

Metatarsus adductus, a common foot deformity in newborns characterized by the inward turning of the forefoot, is primarily believed to arise from the cramped positioning of the fetus in the womb during pregnancy. This positioning can lead to the foot being pushed or molded into an abnormal shape, resulting in the characteristics of the condition.

Fetal positioning for a significant period contributes to the development of metatarsus adductus, as the confined space can restrict normal foot movement and develop the characteristic adducted position. Mobilization and stretching of the foot are usually effective in correcting the condition, especially when addressed early. Understanding this etiology helps guide clinicians in monitoring and managing infants diagnosed with metatarsus adductus.
