The congenital clubfoot is a common congenital foot deformity. Previous surgical treatment of clubfoot has been unsatisfactory and many children have not had their deformity corrected, and in some cases, although the appearance of the foot has improved, it is still stiff, weak, and often painful, and gradually develops into lameness. The Ponseti method was invented by Dr. Ignacio Ponseti. Dr. Ignacio Ponseti invented a horseshoe foot orthopedic treatment method, which has been recognized worldwide. The method is not only less expensive, but also more effective, greatly reduces the pain of the child, greatly reduces the disability caused by clubfoot, and has great advantages compared to surgery. The method is divided into 4 steps: manipulation of the corrective cast, percutaneous Achilles tendon rupture, cast protection, and the wearing of a foot abduction brace. The foot corrected with the Ponseti method was flexible, strong and painless. The method is most effective when treatment is started before the child is 9 months old, with a success rate of over 90%.
