Finger loss has the opportunity to connect, but depends on the time of injury and the degree of tissue contusion, finger loss in medicine is called broken finger, broken finger reimplantation in China is a very mature surgery, in most of the second hospital can be carried out, but there are a few conditions need to be met: 1, general broken finger reimplantation is best to be carried out in the first eight hours after the injury, so that the success rate is relatively high, the finger the chances of survival than the larger, more than eight hours after the tissue necrosis, vascular degeneration, after connecting the blood vessels are prone to blockage, failure. More than eight hours after the tissue necrosis, vascular degeneration, after connecting up the blood vessels are easy to block, can not be, resulting in replantation failure. 2, when the injury tissue contusion is more serious, especially some of the extrusion injuries or chainsaw injuries, the destruction of blood vessels is more serious, after connecting up the blood vessels are prone to clogging and ischemia, necrosis. If the cut wound is caused by knife, glass, etc., the broken end is more neat, the damage to blood vessels and tissues is relatively small, and the chance of survival is higher after being connected.
