After the cast is fixed, try not to remove it by yourself when removing it, you should go to the hospital to find the doctor who gave you the cast for the first time to remove it. First, after the cast is fixed, the most important thing the doctor wants to know is whether there is any loosening or fracture of the cast. Secondly, when removing the cast, you should normally take X-rays to understand the healing of the fracture. If the fracture does not heal well or if there are changes in the fracture such as displacement or angulation, it may be necessary to extend the fixation time, and at the same time, the displacement and angulation of the fracture should be corrected and adjusted. Therefore, cast removal is not a simple removal, but it is necessary to remove the cast and then, depending on the specific situation, some corresponding treatment may be required. If you remove the cast by yourself, you will not make a correct judgment and may delay the condition.
