Q66: Congenital deformities of feet

Congenital deformities of feet are abnormalities present at birth that affect the shape, position, and function of one or both feet. These conditions can result from genetic factors, in-utero positioning, or an issue with the development of the bones, muscles, or nerves in the feet during pregnancy. Types of foot deformities range from mild, such as a slight bend in the toe (clinodactyly), to more severe structural issues, including clubfoot, where the foot turns inward and downward. Symptoms vary, but generally involve unusual foot shape or position that can hinder walking or wearing standard footwear. The abnormalities don't always cause discomfort or pain, but some can lead to complications like balance difficulties, mobility limitation, or developmental issues. The progression of these deformities can remain steady or potentially worsen with growth and weight bearing. Early diagnosis can help manage the severity and impact of the condition.
