1.What is soft tissue polydactyly? When can surgery be done Soft tissue polydactyly often refers to redundant fingers without bony structures, commonly known as redundant fingers. If the tip of the redundant finger is small, the redundant finger has certain risks and is prone to twisted necrosis of the tip, which can be removed after the full moon. It is also believed that soft tissue polydactyly means that there is no bone and joint connection between the polydactyly and the main finger, but only the soft tissue of the skin is connected, which is the simplest type of polydactyly and the earliest type that can be operated, and it is advocated to operate at 3 months of age. 2.What is simple polydactyly? When can surgery be done Simple polydactyly is mostly unilateral, and the clinical manifestations can range from widening of the fingertips to complete duplication of the whole finger. If the child is too young, the respiratory system is immature, the risk of anesthesia is high, and the tendons and ligaments of the hand are poorly developed, so it is not easy to distinguish. However, the period of surgery can also be slightly advanced according to the actual development of the child. For example, the child is well developed, the hospital has a good level of anesthesia, and the surgeon is experienced. 3.What is compound polydactyly? When is the best time to do surgery? If the polydactyly is accompanied by other hand and foot diseases such as polydactyly, it is generally believed that surgery can be done after half a year of age (marginal polydactyly is prone to bent finger deformity, so early surgery is recommended, while central polydactyly can be postponed until 1-2 years old). 4.What is the difference between surgery at age half and surgery at age one? The older the child is, the better the development of the tendons, ligaments and organs of the hand, the more favorable the exposure of surgical field, surgical tolerance and anesthesia. 5.What are the effects of missing the best time for treatment in children with polydactyly? Before the age of 3, it is the golden period of hand function development of children, and surgery before the age of 3 is more favorable for finger function recovery. In addition, the older the child is, the more mature the child’s mental development is. The deformed appearance of the polydactyly will also have an impact on the child’s psychological development, and the psychological shadow in early childhood may become the seed of the child’s inferiority complex in future life, work and study. The older the child is, the greater the impact of the hand deformity itself on the development of the hand shape (especially the development of adjacent fingers) and function, the more complex the deformity and the greater the difficulty of surgery.
