It is more common among Māori people, and less common among Chinese people.Clubfoot disproportionally affects those in low and middle-income countries (LMICs). About 80% of those with clubfoot, or approximately 100,000 children per year as of 2018, are born in LMICs. History
Pharaohs Siptah and Tutankhamun had clubfoot, and the condition appeared in Egyptian paintings. Indian texts (c. 1000 BC) and Hippocrates (c. 400 BC) described treatment. In 1823, Delpech presented another way to treat patient with clubfoot. This new way was tenotomy, which means the cut of the Achilles tendon in those patients. As a surgical procedure it had its complications like infections. Signs and symptoms
In clubfoot, feet are rotated inward and downward. The affected foot and leg may be smaller than the other, while in about half of cases, clubfoot affects both feet. Most of the time clubfoot is not associated with other problems.Clubfoot can be diagnosed by ultrasound of the fetus in more than 60% of cases. The earliest week of gestation in which the condition is diagnosed with a high degree of confidence was the 12th and the latest was the 32nd. Not all patients were diagnosed at an early stage. In 29% of fetuses the first ultrasound examination failed to detect the deformity which subsequently became obvious at a later examination.
Compared to the Ponseti method which uses rigid casts and braces, the French method uses tape which allows for some motion in the feet. Despite its goal to avoid surgery, the success rate varies and surgery may still be necessary. The Ponseti method is generally preferred over the French method. Surgery
If non-operative treatments are unsuccessful or achieve incomplete correction of the deformity, surgery is sometimes needed. Surgery was more common prior to the widespread acceptance of the Ponseti method. The extent of surgery depends on the severity of the deformity. Usually, surgery is done at 9 to 12 months of age and the goal is to correct all the components of the clubfoot deformity at the time of surgery. For feet with the typical components of deformity (cavus, forefoot adductus, hindfoot varus, and ankle equinus), the typical procedure is a Posteromedial Release (PMR) surgery. This is done through an incision across the medial side of the foot and ankle, that extends posteriorly, and sometimes around to the lateral side of the foot. In this procedure, it is typically necessary to release (cut) or lengthen the plantar fascia, several tendons, and joint capsules/ligaments. Typically, the important structures are exposed and then sequentially released until the foot can be brought to an appropriate plantigrade position. Specifically, it is important to bring the ankle to neutral, the heel into neutral, the midfoot aligned with the hindfoot (navicula aligned with the talus, and the cuboid aligned with the calcaneus).
