The symptoms of itchy skin after fracture plate fixation may be caused by local skin allergy at fracture site, skin growth and healing and other factors. 1. Local skin allergy at the fracture site: When the internal fixation surgery with plate is performed after the fracture, the skin tissues at the fracture site may be allergic to the material of internal fixation, antiseptic solution and other substances, which may cause itching, blistering and other uncomfortable symptoms of the skin after the surgery. Therefore, in order to relieve the itching situation, you can take anti-allergy drugs such as paracetamol under the instruction of the doctor. 2. Skin growth and healing at the fracture site During surgery, the skin tissue at the fracture site will be cut, which may damage the nerve endings on the skin. After surgery, the skin grows and heals, which can cause the fracture area to be stimulated by the nerve endings and the symptoms of itching. In conclusion, there are many causes of itchy skin after fracture surgery, and it is recommended to visit a hospital for treatment.
