踝骨, or the ankle bone, refers to the bony structure that forms the ankle joint. It consists of several bones, including the 距骨 (talus) and the 腓骨 (fibula), which connect the foot to the leg. The ankle bone plays a crucial role in supporting body weight and allowing for movement, such as walking and running. In addition to its structural function, the 踝骨 is essential for maintaining balance and stability. Injuries to the ankle, such as sprains or fractures, can significantly impact mobility and require proper treatment to heal. Understanding the anatomy of the 踝骨 is important for athletes and individuals engaged in physical activities.
