Can't.
The cast of a fracture will be removed after it has been fixed for a period of time under the supervision of a doctor, but removing the cast is a specialized operation that needs to be carried out by a professional physician or nurse. Even if the fracture site has recovered, you should not remove the cast on your own because removing the cast requires special tools and skills, and care needs to be taken to ensure the safety of the patient during the removal process.
If you have a fracture, you should not remove the cast on your own.
If you need to have your cast removed, it is important to consult with a medical professional and be under the supervision of a doctor. The doctor will decide whether the cast needs to be removed, as well as when and how to remove it, based on the patient's specific condition.
Before removing the cast, the doctor will also need to conduct an examination and assessment to ensure that the fracture has fully healed and that removing the cast will not affect the patient's recovery.
Therefore, patients should follow their doctor's advice and don't remove the cast privately, as this may affect recovery and healing.
