Timing of treatment: When parents bring their children to the doctor, doctor-patient communication is very important to develop a reasonable and individualized treatment plan based on the condition. Treatment of congenital hand and foot deformities varies according to the extent of the disease. Simple dermatomal polydactyly can be surgically removed early in life. For complex polydactyly with articular skeletal connections, the degree and type of deformity should be fully evaluated before surgery, and it is generally better to remove the deformity at the age of 6 months to 3 years old, and then choose the surgery time before the age of 6 years old, before going to middle school, before high school, before college, before work, before marriage, etc. It is the best to treat the deformity before the age of 3 years old, as the child has not yet arrived at kindergarten, and will not be discriminated against by the other children, and at the same time, the child will not have much memory, at most when the child is older. There is no memory, at most, when the child is older and ask why there is a cut, as long as you tell the child hours of naughty scratched to the hospital stitches, on the child’s healthy growth is good.
