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
Femur on average. An abnormal increase in the angle is known as coxa valga and an abnormal reduction is called coxa vara. Both the head and neck of the femur is vastly embedded in the hip musculature and can not be directly palpated. In skinny people with the thigh laterally rotated, the head of the femur can be felt deep as a resistance profound (deep) for the femoral artery. The transition area between the head and neck is quite rough due to attachment of muscles and the hip joint capsule. Here the two trochanters, greater and lesser trochanter, are found. The
