Tibia they afford attachment to the anterior and posterior ligaments of the lateral malleolus. The medial surface -- see medial malleolus for details. Ankle fractures of the tibia have several classification systems based on location or mechanism: The tibia is supplied with blood from two sources: A nutrient artery, as the main source, and periosteal vessels derived from the anterior tibial artery. The tibia is a part of four joints; the knee, ankle, superior and inferior tibiofibular joint. In the knee the tibia forms one of the two articulations with the femur, often referred to as the "tibiofemoral components" of the
Body of femur includes the portion between the medial border and the linea aspera; it is continuous above with the lower border of the neck, below with the medial side of the medial condyle: it is covered by the Vastus medialis. Body of femur The body of the femur (or shaft), almost cylindrical in form, is a little broader above than in the center, broadest and somewhat flattened from before backward below. It is slightly arched, so as to be convex in front, and concave behind, where it is strengthened by a prominent longitudinal ridge, the linea aspera. It presents for examination three
