The tibia is the shin bone.

X-ray from the front of the joint, showing the articulation of the tibia with the femur above and with the fibula at the side. On the plateau of the tibia you can see the central tibial spines where the cruciate ligaments (which do not show on X-ray) attach. The two menisci sit atop the tibial plateau. They are not evident on the X-ray, appearing only as a 'gap' between the two long bones.

Illustration showing the main relations of the upper end of the tibia. The tibia joins to the femur via a mobile articulation but to the fibula via a relatively immobile fibrous syndesmosis.
