The Shin & Calf Chassis
The two bones of your lower leg
Above the foot, two long bones form the chassis of your lower leg. The tibia is the heavy-duty pillar that carries your weight, and the fibula is the skinny sidekick that helps with balance.

Tibia
aka The Pillar
Your shin bone — the big one. It carries almost all of your weight from your knee down to your ankle. It's the second-longest bone in your body and one of the strongest.
Pillar and sidekick
The tibia and fibula work as a team. The tibia is the pillar — it takes the load. The fibula is the sidekick — it adds stability and gives muscles a place to attach. Together, they connect your knee to your ankle and keep you standing tall.
