Here is only a brief description of the choice of surgery time for general congenital deformities, such as syndactyly, polydactyly, short finger deformity, etc. The following two aspects are taken into consideration in the selection of the surgery time: 1. The child develops a little bit, grows up a little bit, so that the risk of surgical anesthesia is reduced and the difficulty is reduced; the operation is also convenient, which facilitates more delicate surgical operations; the post-operative care of the child will be more convenient. These factors will directly affect the results of the surgery. 2, to prevent the existence of deformities to the child caused by psychological shadows, so to operate before the child understands, at least in the child to kindergarten, before the start of group life. Considering the above two points, the best time to operate is at the age of 1.5 years (18 months). This is the choice of the hand surgery department of Beijing Jishuitan Hospital. It is important to emphasize that the child’s deformity will certainly make the parents uncomfortable, in the face of the strange eyes of outsiders, psychological pressure, reluctant to take the child to friends and relatives, in front of the public, hoping to give the child surgery orthopedic as soon as possible, which is understandable. However, parents must resist the pressure, because we have a common goal, which is to give the child the best treatment, and the best treatment needs to have the best time for treatment. Of course, if the deformity is progressively worse, or if the deformity will have other serious effects, surgery will have to be done earlier.
