We opened our personal webpage only in March and received many inquiries from patients, more than 60% of which were for “broken foot”. Most of these patients are not able to get timely and correct treatment after “broken foot” and leave serious sequelae. Therefore, it is necessary to popularize the knowledge about “broken foot”. Commonly known as “broken foot” or “ankle injury” is medically known as ankle sprain. The ankle is an important weight-bearing joint in the human body, and its stability is maintained by the medial ligament complex, the lateral ligament complex, and the inferior tibiofibular ligament complex. The ligaments in these areas are not as strong as the ligaments around other large joints and are therefore more susceptible to injury when subjected to external forces.
