The immobilization time of cast for minor fracture is not standardized, usually 1~2 months, which is subject to individual differences and cannot be generalized. The immobilization time of cast for minor fracture is related to the fracture site and individual recovery, for example, x-ray for minor fracture of upper limb should be reviewed in about 1 month, and for minor fracture of lower limb should be reviewed in about 1.5 months. If there is scab formation between the fracture ends, the cast can usually be removed; however, if there is no scab formation between the fracture ends, then the removal time needs to be delayed. Therefore, the cast removal time for minor fractures is subject to individual differences and cannot be generalized. After removing the cast, it is necessary to carry out appropriate functional exercises in a gradual manner, so that the fractured part can continue to recover and promote the muscles to regain strength. It is recommended that the patient should follow the doctor’s instructions for review, and if there is any discomfort during the period of cast immobilization, follow up with the doctor and get the corresponding measures from the doctor.
