Principles of management of congenital clubfoot

  Congenital clubfoot is a common birth defect and a common deformity of bones and joints in children, and is one of the common causes of functional disability of bones and joints in childhood and adulthood. In our clinical practice, we often hear the question: Can clubfoot be treated? What is the best way to treat it? This is a controversial issue even among medical colleagues. Before answering these questions, we need to clarify, what is congenital clubfoot?  1. What is congenital clubfoot?  Horseshoe clubfoot is a deformity of the foot and ankle, and its visible deformities include plantar flexion deformity of the ankle joint, inversion of the hindfoot, and inversion, inversion and plantar flexion of the midfoot and forefoot. When we refer to congenital clubfoot, we mean that the cause is not known and that only clubfoot deformity is present without other deformities, excluding those cases of clubfoot deformity that have a known cause and are part of a syndrome, also known as idiopathic clubfoot.  Horseshoe clubfoot is not an embryologic malformation; the development of normal feet into horseshoe clubfoot occurs during the fourth to sixth months of pregnancy, and ultrasonography rarely sees horseshoe clubfoot malformations in fetuses before 16 weeks; therefore, horseshoe clubfoot is a developmental malformation. The pathological changes of clubfoot are associated with abnormalities in both bone and soft tissue structures. Due to its malformed appearance, clubfoot can be detected at birth and is generally diagnosed without difficulty, but it needs to be differentiated from spina bifida, polyarticular contracture and postural clubfoot. Since clubfoot can be detected early, the next question is, can clubfoot be treated? What method of treatment is effective?  2, congenital clubfoot can be treated?  In our clinic, we once encountered such a case, a couple just got their baby, very happy, but to their dismay, the child’s feet are “crooked feet” (that is, clubfoot), neighbors and relatives think that this is “incurable”, they even decided to abandon the child. They even decided to abandon the child. We have also encountered many cases where parents found out that their child had clubfoot and went to the local doctor for treatment.  The medical profession used to widely promote surgical treatment methods for congenital clubfoot. Due to the late treatment, the surgery is more traumatic and the foot tissues are more damaged, often resulting in joint stiffness, walking pain, foot exostosis, osteoarthritis and talar necrosis, etc. The comprehensive efficacy assessment is not satisfactory, and the long-term functional results mostly have many problems, affecting the activities of the foot and ankle and the patients’ quality of life.  Through a large number of studies, most scholars have reached a consensus in recent years on the following issues: if congenital clubfoot can be treated appropriately at an early stage, most of them can obtain a better correction of the deformity; if it is not treated, it will be disabled for life and affect life and work. The initial treatment of congenital clubfoot should be non-surgical, and the neonatal period is the best time to treat congenital clubfoot.  The Ponseti method, developed by Professor Ponseti and his colleagues at the University of Iowa, has been widely recognized by medical colleagues in many countries around the world for its long-term functional results, and has become a simple, cost-effective and recommended treatment for congenital clubfoot by the World Health Organization (WHO) after decades of follow-up studies.  All deformities of the clubfoot can be corrected simultaneously by the Ponseti method through gentle manipulation, which consists mainly of early continuous cast orthosis with percutaneous Achilles tendotomy (very minimal trauma) and supplemented with an abduction brace. Treatment can be started within the first few days of life, and with the Ponseti method, the success rate of treatment of clubfoot exceeds 90%, even achieving the goal of a completely normal foot. Therefore, we now advocate “early detection and early treatment, more hands and less surgery” for the treatment of congenital clubfoot.
