The tibiofibular joints are a set of articulations that unite the tibia and fibula. These two bones of the leg are connected via three junctions; The superior (proximal) tibiofibular joint - between the superior ends of tibia and fibula. The inferior (distal) tibiofibular joint - between their inferior ends.
The distal tibiofibular syndesmosis/inferior tibiofibular joint is a syndesmotic joint. It is formed between the distal tibia (concave surface) and fibula (convex surface), with no articular capsule or synovial membrane as a fibrous joint, and attached by the interosseous ligament (IOL), the anterior-inferior tibiofibular ligament (AITFL), the ...
The proximal and distal tibiofibular joints refer to two articulations between the tibia and fibula of the leg. These joints have minimal function in terms of movement, but play a greater role in stability during movement and weight-bearing.
The syndesmotic articulation of the distal tibiofibular joint occurs between the convex surface of the distal tip of the fibula and the concave fibular notch of the distal tibia. The stability of the syndesmosis is crucial to proper dynamic ankle and lower extremity function.
In this article we described in detail the anatomy of the separate osseoligamentous structures of the distal tibiofibular joint, which is a complex syndesmotic joint, and discussed the clinical relevance of these structures.
The posterior tibiofibular ligament descends posteriorly to the syndesmosis between the tibia and fibula. The distal part of this ligament, the inferior transverse ligament, is a yellow band that connects the medial and lateral malleoli.
The tibiofibular syndesmosis, on the other hand, is a compound fibrous joint. Basically, it represents the fibrous union of the tibia and fibula by means of the interosseous membrane, which unites the shaft of the bones, and the inferior tibiofibular joint, which unites the distal ends of the bones.
Learning Objectives. By the end of this section, you will be able to. Discuss the structure of specific body joints and the movements allowed by each. Describe the bones that articulate to form selected synovial joints. Explain the movements available at each joint. Describe the structures that support and stabilize each joint.
A stable and precise articulation of the distal tibiofibular syndesmosis is essential for normal motion of the ankle joint. Injury to the syndesmosis occurs through rupture or bony avulsion of the syndesmotic ligament complex.
The distal tibiofibular joint is a fibrous joint located between the lower ends of the tibia and fibula bones in the leg. It provides stability to the ankle joint by allowing slight movement between these bones.
