Congenital polydactyly is a very common clinical condition and one of the most common congenital disorders in children, with a significant impact on appearance and walking function. The exact cause of congenital polydactyly is unknown, but it is generally believed to be related to environmental and genetic factors. Congenital toe deformities include: floating toe, polydactyly, syndactyly, multiple syndactyly, bunion, and megalodactyly, which can seriously affect the appearance and function of the foot. In addition to the physical effects, children and parents often have psychological shadows, which often affect the child’s psychological development, learning and social life, and even affect future employment, work and marriage. The diagnosis of congenital syndactyly can be made on the basis of medical history and clinical physical examination. Treatment: When parents bring their children to the doctor, it is very important to communicate with the doctor and to develop a reasonable and personalized treatment plan based on the condition. Treatment for congenital polydactyly varies depending on the extent of the disease. Simple dermatomal polydactyly can be surgically removed early in life. For complex polydactyly with jointed bones, the extent and type of deformity should be fully evaluated before surgery. The most children will ask why there is a cut when they are older, as long as they tell the child that they were naughty when they went to the hospital to get stitched up, which is good for their healthy growth.
