Whether a severed finger can be reimplanted depends on the severity of tissue damage after severance, the time of severance, and the patient’s own wishes to decide whether it can be reimplanted. If the severed finger is caused by machine cutting injury, the time of severance is shorter, and regular low temperature preservation, the severed end of the tissue is generally less damaged, it can be reimplanted, and the survival rate after reimplantation is also higher. If the finger is severed due to heavy crushing injury, extrusion injury caused by the severance of both sides of the severed end of the tissue damage is more serious, most of the blood vessels and nerves are damaged. In this case, replantation is not recommended, and even if replanted, the survival rate is small. If the time of severance is within 6~8 hours, most of them have hope for replantation. Beyond that, the chance of survival is low and reimplantation is not recommended. Re-implantation is more expensive and takes longer, so it is necessary to fully communicate with the patient and consider the patient’s wish to choose whether to re-implant or not. If you are unfortunate enough to have a severed finger, it is recommended that you go to the hospital in time for a checkup and decide whether or not to choose reimplantation surgery after being examined by a doctor.
