If the broken finger is caused by a fracture, the broken finger can heal completely after the fracture is healed and the bone scabs have grown and the bone cells have developed well. If the broken finger was injured by a sharp object or something else, the recovery time is longer, and the patient needs to exercise strictly under the guidance of the doctor during this period, gradually increasing the intensity of the activity from small to large strengths, slowly strengthening the intensity of the activity and slowly adapting to it, in order to ensure a good recovery of the broken finger. The patient must also consciously perform flexion and extension activities to ensure the flexibility of the finger, but must be careful to do so slowly. Because of the stiffness of the broken finger, anxiety can easily cause secondary injury, and there is also a risk of vascular nerve damage. This type of injury cannot be restored to its original state, but only to its best condition. Patients are advised to go to the hospital for examination, cooperate with the doctor’s treatment, and then take dietary therapy to promote early wound healing.
