The lateral ligament is a crucial component of your body's skeletal structure. It stabilizes your ankle joint by connecting the fibula bone to the talus and calcaneus bones. However, there are several synonyms for the lateral ligament. Some of these include the external lateral ligament, fibular collateral ligament, and lateral collateral ligament. These terms refer to the same structure, which plays a vital role in maintaining the stability and flexibility of your ankle. Whatever term you use, it is important to understand the location, structure, and function of the lateral ligament to ensure that your ankle remains healthy and strong.
