All clubfeet are not of the same severity, although all have the same general appearance. The feet are twisted inward so that the top of the foot is where the bottom should be. There is often a deep crease on the bottom of the midfoot.
Clubfoot may occur as an isolated disorder (idiopathic) or in combination with various syndromes and other associated anomalies such as arthrogryposis and myelodysplasia. Medical examinations by your doctor or blood tests should be able to determine whether your baby’s clubfoot is idiopathic.
Clubfoot can be mild or severe and all cases require treatment. Clubfoot will not resolve without treatment. The clubfoot is not painful to the infant who does not yet walk.
The incidence of idiopathic clubfoot is estimated to be one to two per 1000 live births. It has a male predominance of 2:1 and occurs in both feet about 50 percent of the time. There is a much higher incidence if the patient has a positive family history of clubfoot.
The etiology of idiopathic clubfoot is unknown. The most widely accepted theory is that clubfoot is caused by a combination of genetic and environmental factors.
