The incidence of congenital clubfoot is about 1 in 1,000. The cause of the disease is still unclear. During fetal development, the foot forms deformities such as inversion, internal rotation, high arch and horseshoe, while the calf muscles below the knee are dysplastic and small, and if not treated in time, the calf muscles can atrophy to become skin and bone like, and the bones of the foot are gradually deformed to walk on the lateral side of the back of the foot, which is painful and difficult to walk. The disease is easy to diagnose and can be detected after birth. Previous treatments: braces, massage, extensive soft tissue release of the foot after 1 year of age, triple joint fusion, etc. Although it improves the appearance, the foot is stiff, short and painful to walk, making it difficult to achieve a satisfactory outcome. The Ponseti (Ponseti) series of manual repositioning, plaster progressive orthopedic treatment method, completely overturned the previous treatment concept, to obtain a normal appearance, foot movement, walking pain-free normal foot, completely solved the problem of treatment of this disease, known as a milestone in the history of orthopedic development. The technique was proposed by American Professor Ponseti on the basis of an in-depth study of the pathology and anatomy of the disease, and the repositioning of the talocrural joint became the key link for all deformities of the foot to be corrected. By manipulating the forefoot to rotate back and abduct, the thumb topped the talar head, then the forefoot inversion was corrected, the midfoot high arch disappeared, the talocrural joint was repositioned, the heel bone was automatically corrected inversion in the subtalar joint, and through progressive repositioning and contracted soft tissue progressive Eventually, the bones and joints of the foot are restored to their normal anatomical relationship. Professor Ponseti has been using this method to treat clubfoot for more than 50 years, and its efficacy has been recognized and promoted all over the world, and has been introduced to China since 2000, making a great contribution to the treatment of osteoarthritis in children.
