Generally speaking, the result of finger reconstruction surgery will be the best when it is performed in adulthood. If the reconstructive surgery is performed in childhood, the child will be active and not easy to cooperate with the surgeon, which will affect the surgical effect and even cause surgical failure; if the reconstructive surgery is performed in adulthood, such as the end of the finger, it will not affect the function of the patient’s hand; if it is for the reconstruction of a long finger, it will have an impact on the function of the hand. The first week after finger reconstruction surgery is the key period of recovery, the affected limb should be braked, and after 1 week, functional rehabilitation training can be carried out.
