Q

What do the conduces of the femur articulate with?

A

The tibia and patella.

16
Q

What is the role of the femur when standing?

A

Transmits the weight from the tibia to the hip bone.

17
Q

What can be a consequence of an intra capsular fracture of the femur?

A

Avascular necrosis because the medial femoral circumflex artery can become damaged.

What do the 2 condyles of the tibia form?

A

The tibial plateau
