TibiaFibula

The tibia and fibula are the two bones that make up the lower leg. The tibia, also known as the shinbone, is the larger and stronger of the two bones. It is located on the medial (inner) side of the leg and articulates with the femur (thighbone) at the knee and with the talus (ankle bone) at the ankle. The fibula is a thinner bone that runs parallel to the tibia on the lateral (outer) side of the leg. It articulates with the tibia at the proximal and distal ends and also articulates with the talus at the ankle, though to a lesser extent than the tibia.

Together, the tibia and fibula provide support for the body's weight, serve as attachment points for muscles, and are crucial for locomotion. The tibia bears the majority of the weight transferred from the knee to the ankle. The fibula's primary role is to provide stability to the ankle joint and serve as an attachment site for several muscles of the lower leg and foot. Fractures to either the tibia or fibula, or both, are common injuries resulting from trauma, falls, or high-impact activities. These fractures can range in severity from simple cracks to complete breaks, often requiring medical intervention such as casting or surgery for proper healing.
