Frequently broken feet and bones have no great relationship, often broken feet and ankle joint capsule fiber layer thickening formation of three groups of ligament laxity, including the medial collateral ligament, lateral collateral ligament and lower tibiofibular ligament. 1. Medial collateral ligament: also known as the deltoid ligament, is the strongest ligament in the ankle joint, mainly preventing ankle valgus. If the medial collateral ligament is lax, it is prone to lateral instability of the ankle joint, resulting in repeated wounds. 2. Lateral collateral ligament: it starts from the ankle and ends at the anterolateral aspect of the talus, lateral aspect of the heel bone and posterior aspect of the heel bone in three bundles, which is the weakest ligament in the ankle. If the lateral collateral ligament is loose, the instability of the ankle joint in all directions can also lead to frequent wounds. 3. Inferior tibiofibular ligament: deepens the anterior and posterior aspects of the ankle points, stabilizes the ankle joint, when the inferior tibiofibular ligament is lax, it can also lead to frequent broken feet. Therefore, frequent broken feet is not a bone problem, mainly due to ligament laxity, patients should go to the hospital in time, under the guidance of the doctor for formal treatment.
