A cast on a dislocated finger can usually be removed in about a month, and the exact removal time varies from person to person. If the finger is in a cast, it can usually be removed after a month of reasonable rest and rehabilitation can be attempted to avoid joint deterioration and muscle atrophy. However, care should be taken to avoid excessive activities that may cause secondary injury to the affected area. If the condition is severe, the removal time will be relatively longer. In the case of finger dislocation, the patient should be careful to elevate the affected part during the recovery period, so as to promote the return of blood flow. At the same time, it is important to eat a well-balanced diet and to reduce the consumption of spicy and irritating foods. If a finger dislocation occurs, the patient should go to the hospital for a relevant examination, and then under the guidance of the doctor to choose the appropriate treatment for treatment, follow the doctor’s instructions.
