tibiofibular

Tibiofibular Syndesmosis (syndesmosis tibiofibularis; inferior tibiofibular articulation).

III. Syndesmology. 7c. Articulations between the Tibia and Fibula 1918

This is obtained by a slight outward rotatory movement of the lower end of the fibula and a stretching of the ligaments of the syndesmosis; this lateral movement is facilitated by a slight gliding at the tibiofibular articulation, and possibly also by the bending of the body of the fibula.

III. Syndesmology. 7d. Talocrural Articulation or Ankle-joint 1918

Its upper margin does not quite reach the tibiofibular joint, but presents a free concave border, above which is a large, oval aperture for the passage of the anterior tibial vessels to the front of the leg.

Interosseous Membrane (membrana interossea cruris; middle tibiofibular ligament).

III. Syndesmology. 7c. Articulations between the Tibia and Fibula 1918

Tibiofibular Articulation (articulatio tibiofibularis; superior tibiofibular articulation).

It then runs behind the tibiofibular syndesmosis and divides into lateral calcaneal branches which ramify on the lateral and posterior surfaces of the calcaneus.

VI. The Arteries. 1F. The Posterior Tibial Artery 1918

It ascends in front of the Popliteus, which it supplies, and anastomoses with the inferior genicular branches of the popliteal artery, giving an offset to the tibiofibular joint.

VI. The Arteries. 6d. The Anterior Tibial Artery 1918

—In these articulations the contiguous bony surfaces are either connected by broad flattened disks of fibrocartilage, of a more or less complex structure, as in the articulations between the bodies of the vertebræ; or are united by an interosseous ligament, as in the inferior tibiofibular articulation.

III. Syndesmology. 3. Classification of Joints 1918

The Perforating Branch (ramus perforans; anterior peroneal artery) pierces the interosseous membrane, about 5 cm. above the lateral malleolus, to reach the front of the leg, where it anastomoses with the anterior lateral malleolar; it then passes down in front of the tibiofibular syndesmosis, gives branches to the tarsus, and anastomoses with the lateral tarsal.

VI. The Arteries. 1F. The Posterior Tibial Artery 1918

It is continuous below with the interosseous ligament of the tibiofibular syndesmosis, and presents numerous perforations for the passage of small vessels.
