Internal and external ankle fractures are more serious fractures for the following two reasons: First, internal and external ankle fractures will cause ankle joint instability and ankle dislocation, which will result in severe limitation of ankle joint function if left untreated. Secondly, fractures involving the joint have high requirements in treatment, which need to achieve precise anatomical repositioning and strong fixation to avoid traumatic arthritis after recovery. If traumatic arthritis occurs, it will seriously affect the function of the ankle joint, which will affect the patient’s standing and walking, and lead to a significant decrease in the quality of life. Therefore, ankle fracture is very serious both in terms of the joint part and the type of fracture, and it must be treated in a very formal and correct way, and it is recommended to carry out surgical treatment.
