It is the supporting bone of the lower leg and runs parallel to the narrower lower leg bone, the fibula, to which it is attached by ligaments. The tibia, or shinbone, articulates with the femur, or upper leg bone, at the knee and extends to the ankle bone. On the inside of the ankle, the tibia widens and protrudes to form a large bony prominence called the medial malleolus. Fracture of the tibia The tibia is one of the most commonly fractured bones. It may break across the shaft as a result of a direct blow to the front of the leg, or at the upper end from a blow to the outside of the leg below the knee. Fracture of the lower edge of the tibia may accompany dislocation of the ankle and fracture of the fibula in a Pott's fracture, caused by violent twisting of the ankle. Prolonged running or walking on hard ground may cause a stress fracture of the tibia. Some fractures of the shaft heal satisfactorily if the leg is immobilized in a plaster cast, usually for about six to eight weeks. If the bone ends are displaced or unstable, an operation may be needed to fasten them together with a nail or screw.
