Divided into thirds

Proximal third – closer to the head or cranial end of the body

Proximal third – closer to the head or cranial end of the body

Middle third

Proximal third – closer to the head or cranial end of the body

The Fovea provides attachment for the Ligamentum Teres

(ligament of the head of the femur)

This attaches to the acetabulum of the pelvis and helps stabilise the hip joint

Distal Femur

Distal Femur – anterior view

If the shaft is held perpendicular to the floor, the medial condyle is seen to project further inferiorly compared to the lateral condyle

right femur

In the upright skeleton, the shaft of the femur lies obliquely and the condyles

appear to be aligned distally

If the shaft is held perpendicular to the floor, the medial condyle is seen to project further inferiorly compared to the lateral condyle
