Whether or not a severed finger can recover as normal after it is attached cannot be generalized, it is closely related to the specific injury, surgical procedure, post-operative care, rehabilitation exercises and other factors, if the patient recovers successfully during the perioperative period, it is generally possible to restore normal function. Finger reimplantation refers to the surgery to reattach the completely or incompletely severed finger back to its original position under the microscope, to restore blood circulation, to make it alive and restore certain functions. Under normal circumstances, after the reimplantation surgery, the perioperative care can ensure the survival of the severed finger, and then under the guidance of the doctor to carry out the functional exercise of the affected finger, the sensory and flexion/extension functions of the affected finger can be restored to normal or close to normal. After the broken finger is connected, because the fracture of the affected finger and the surrounding tissues still need a period of time to repair, so you need to pay attention to the maintenance of the affected finger within 3 months after discharge from the hospital, you should pay attention to the finger heat preservation, avoiding cold stimulation and extrusion, avoiding stimulating food, strictly prohibit smoking and alcohol, so as not to affect the local blood circulation, if the maintenance and care is not proper, it may also result in the possibility of necrosis of the affected finger again.
