Six-finger deformity is mostly seen in children and is usually a congenital developmental problem. The general cost of surgical treatment is about 5,000 yuan, which is highly dependent on the local economy and the level of the hospital. Surgery for hexodactyly is usually performed at the age of one year or older, when the child can tolerate anesthesia, and is completely cured after surgical removal. If the child cannot distinguish the dominant finger at the age of one year, he or she can continue to be observed until the age of 3-4 when the dominant finger is obvious. After surgery, keep the wound dry and hygienic, and insist on changing the wound medication. After surgery, strengthen the care, avoid local contact with water or repeated friction and pressure on the wound to help recovery.
