The fibula bone, also known as the calf bone, is a slender bone located on the lateral side of the lower leg. It runs parallel to the tibia, the larger bone in the lower leg. The fibula plays a key role in providing structural support to the leg and ankle. Despite being the smaller of the two lower leg bones, the fibula plays an important role in stabilizing the ankle joint and providing attachment points for muscles and ligaments. Injuries to the fibula can vary in severity, from minor fractures to more serious breaks that may require surgical intervention. Understanding the anatomy and function of the fibula bone is crucial for healthcare professionals, athletes, and individuals recovering from lower leg injuries.
