The time to remove the cast for conservative treatment of a fracture will depend on the recovery and the type of fracture. It usually takes 2 to 12 weeks. Fracture immobilization should wait until clinical healing, and X-rays must be taken to determine fracture healing before removing the external immobilization device. The clinical healing time varies due to different fracture sites, such as metacarpal fracture healing for 2 weeks on average, upper extremity fracture for 5~7 weeks, femoral neck fracture takes 12 weeks, etc. Fractures are usually immobilized for a period of time and then reviewed in the hospital. X-rays show that the fracture line is blurred and the fracture is healing well, then the cast can be removed. If a fracture of a certain part is diagnosed, it is recommended to go to the hospital in time and under the guidance of the doctor for standardized treatment to reduce the adverse effects.
