Fractured foot with broken bone inside may be due to comminuted fracture or avulsion fracture, etc. The treatment mainly includes conservative treatment and surgical treatment. 1. Conservative treatment: If the fracture is avulsion fracture, the fracture line is well aligned, the integrity of the joint surface is not affected, and the possibility of free bone is relatively small in the later stage, you can choose plaster or support fixation, and the fixation time is usually 4~6 weeks. Follow-up observation of fracture healing, and at the same time give mannitol and other swelling, promote bone healing treatment, the above drugs need to be used under the guidance of the doctor, avoid self-medication. 2. Surgery: If the fracture is a comminuted fracture and the fracture line has spread to the joint surface, surgery is usually needed. Surgery is usually performed by incision and internal fixation, removing the fragmented bone and fixing it with Kirschner’s pin or small steel plate, and bone grafting may be needed if the defect is relatively large. After surgery, immobilization in a cast or brace is still required, as well as symptomatic treatment. The same symptom, the cause of the disease is different, the treatment is different, should be standardized treatment under the guidance of the doctor.
