Tibia and Fibula Bones – Introduction

Introduction to the Tibia and Fibula Bones:

The image descriptiontibia (os tibia) and image descriptionfibula (os fibula) are the bones that support the leg. The larger tibia or shinbone is located medial to the fibula and bears most of the weight.

  1. At the superior (proximal) end of the tibia, a pair of flattened condyles articulate with the rounded condyles at the distal end of the femur to form the image descriptionknee joint or tibiofemoral joint.

Articulation points of the tibia and fibula
  • At the knee, a superior (proximal) tibiofibular joint is formed by the lateral tibial condyle and the head of the fibula.
  • At the ankle, an inferior (distal) tibiofibular joint is formed by the lower fibula and a lateral concavity (notch) on the lower tibia.
  1. A socket formed by the distal ends of the tibia and fibular articulates with the superior portion of the talus (foot tarsal bone to form the image descriptionankle (talocrural) joint.
