Inferior tibiofibular joint
Joint in the legs of certain mammals

The inferior tibiofibular joint, also known as 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.
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:
Anterior ligament of the lateral malleolus
Posterior ligament of the lateral malleolus
Interosseous membrane of leg
The inferior transverse ligament of the tibiofibular syndesmosis is included in older versions of Gray's Anatomy, but not in Terminologia Anatomica. However, it still appears in some anatomy textbooks.
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".
The public source identifies “Inferior tibiofibular joint” as joint in the legs of certain mammals. This brief keeps that definition visible, then builds a research path around Inferior, tibiofibular and joint.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Inferior tibiofibular joint”, the useful work is to connect “joint in the legs of certain mammals” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 28, 2025. The linked authority identifier is Q6029430. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
