Inferior tibiofibular joint

The distal tibiofibular joint (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia.

Anatomical terminology

Below, to the extent of about 4 mm, these surfaces are smooth and covered with cartilage, which is continuous with that of the ankle joint.

The ligaments are:

The inferior transverse ligament of the tibiofibular syndesmosis is included in older versions of Gray's Anatomy, but not in Terminologia Anatomica.[1] However, it still appears in some anatomy textbooks.[2]

It should not be confused with the superior tibiofibular joint, which is the only synovial tibiofibular joint, and is sometimes simply called the "tibiofibular articulation".
