Fracture casts should not be removed on your own, as they need to be checked for healing before they are removed and assessed for stiffness and mobility after removal, which needs to be done by a medical professional. External cast immobilization is a common means of fracture treatment. The duration of cast immobilization varies for each type of fracture, but is usually 1~2 months. When to remove it, it needs clinician’s comprehensive judgment based on whether the fracture line is blurred or disappeared in X-ray examination, whether there is continuous bone scab generation, whether the local symptoms are improved, etc. to decide whether it can be removed or not, since the relevant examination can not be completed before removing it by oneself, so it can not be removed by oneself. On the other hand, due to the long-term braking, it will affect the joint and limb movement function to a certain extent, after removing the cast, it is necessary to assess the movement condition of the injured limb and provide targeted rehabilitation guidance. Fracture immobilization cast should not be removed by yourself, if you need to remove the cast, it is recommended to go to the hospital.
