When itching at the fracture site occurs, the following reasons should be considered: First, during the self-healing process of the fracture, in the self-healing of the soft tissue injury, there will be local itching in itself. It can appear in a portion of patients, is a normal phenomenon, and does not require special treatment. Secondly, in the case of fracture, it is often necessary to use a cast or brace for fixation. Due to the poor permeability of the cast, long-term fixation may lead to localized dampness of the skin and skin eczema may appear, and itching at the fracture site may occur at this time. Be sure to remove the cast early, observe the condition of the skin, and actively use dermatological medications, such as dexamethasone ointment for symptomatic treatment, and change the cast regularly to avoid moisture.
