Congenital clubfoot is the most common congenital foot deformity in children, seen in about one out of every 1000 births, with varying severity. It is more common in boys. It is characterized by foot drop, inversion of the forefoot and inversion of the hind foot. Examination reveals an inversion of the heel bone with the posterior end upward. In reality, it is a series of skeletal, joint and soft tissue deformities of the foot and ankle centered on the talus deformity. According to the etiology, it can be divided into: 1. postural: probably caused by intrauterine position in late pregnancy; 2. idiopathic: the most common, typical manifestation of clubfoot with moderate stiffness; 3. teratogenic: mostly complicated by polyarticular contracture, cremasteric dysplasia and other systemic diseases, with very stiff feet. Clinical physical examination is easy to diagnose, and X-ray examination helps to evaluate the degree of deformity and select the treatment plan. Treatment: The aim of treatment is to correct the deformity, maintain the flexibility and muscle strength of the foot, and maintain a normal weight-bearing surface. At present, most of the regular medical units at home and abroad use Ponseti plaster orthosis, combined with Achilles tendon lengthening and brace treatment. Treatment is best started within the first month of life if the child’s physical condition allows. The doctor gives the affected foot a gentle pull and massage to reset the joint. The talocrural joint is repositioned first, then the inferior talocrural area is repositioned, and the foot droop is corrected after the group. Generally, the cast is changed once a week, and after most of the deformities are corrected about 5 times, the Achilles tendon is extended under anesthesia with a small percutaneous incision pick, and then the cast is fixed for 3 weeks, and then the cast is removed and replaced with brace treatment. The cast was then removed and replaced with a brace. The brace was worn 24 hours a day for the first 3 months and then gradually reduced under the guidance of the doctor. The brace was worn at night after walking. Of course, the cast correction time and brace wearing time will be changed individually depending on the severity of the child’s condition. After regular treatment, most children with clubfoot can obtain satisfactory results and will have a normal gait. For a small number of children with stiffness or recurrent deformity, surgical treatment such as tendon transfer, joint gentleness, osteotomy, etc. may be required.
