In clinical practice, a patient with a fracture of the lower leg should be seen in a timely manner, and a clear diagnosis should be made by a regular hospital. If a patient has a multi-segment fracture or a comminuted fracture of the lower leg, and after proper treatment, the patient has a rotational deformity or a shortening deformity of the broken end, the patient can be assessed as having a Grade 9 disability. If a patient has a fracture of the lower leg and still has functional impairment in the knee or ankle joint after treatment, the patient can be assessed as a Grade 8 disability, and the specific disability assessment criteria should be based on the standards promulgated by the state.
