The fibula and tibia are the two long bones of the lower leg. The fibula, or calf bone, is a small bone located on the outside of the leg. The tibia, or shinbone, is the weight-bearing bone and is in the inside of the lower leg.
The fibula and the tibia join together at the knee and ankle joints. The two bones help to stabilize and support the ankle and lower leg muscles.
A fibula fracture is used to describe a break in the fibula bone.
