An estimated one out of 1,000 children is born with clubfoot. This number does not vary significantly across ethnic or socio-economic groups. As a result, the condition is spread evenly throughout all populations and countries. About half the cases are bi-lateral (both feet affected). Slightly more boys than girls are affected.
Eighty percent of the roughly 200,000 children born with clubfoot each year live in developing countries. The University of Iowa estimates that fewer than 3% (approximately 20,000-30,000) of the roughly 800,000 children born with clubfoot in developing countries in the last five years have been treated with the Ponseti Method. It is estimated that up to 80% of the remaining 770,000 children have received no treatment at all. Those who have received treatment are most likely to have been treated with a combination of poorly implemented castings, which aggravate the problem, and surgery, usually once the child is over the age of five, resulting in stiff, painful and partially corrected feet.
Of those treated with the Ponseti Method, little is known about how well treatment has been implemented. Data on brace compliance and long-term relapse rates in developing countries Is limited, in part because most projects have only focused on the casting phase of treatment, paying less attention to the equally important bracing phase.
miraclefeet conservatively estimates over 1 million people live with untreated clubfoot around the world. Other organizations believe there could be as many as 3 million living with untreated clubfoot.
