Corpus: Tibiofibular joint

The articulatio tibiofibularis is an articulated connection between the tibia (shin bone) and the fibula (calf bone).

A distinction is made between the superior tibiofibular articulation on the proximal lower leg and the inferior tibiofibular articulation on the distal lower leg. Both joints are compensatory or secondary joints that only allow small, sliding displacement movements of the lower leg bones involved.

Superior tibiofibular articulation[Bearbeiten]

The superior tibiofibular articulation is an amphiarthrosis between the lateral condyle of the tibia and the fibular head (caput fibulae). The two bone surfaces that touch each other consist of flat, oval cartilage facets that are connected to each other by a joint capsule with attached ligaments:

• Ligamentum capitis fibulae anterius
• Ligamentum capitis fibulae posterius

Articulatio tibiofibularis inferior[Bearbeiten]

The articulatio tibiofibularis inferior is a syndesmosis formed by the medial side of the lower end of the fibula and the lateral side of the tibia. Both bone surfaces are covered with a small cartilage field that merges into the cartilage of the ankle joint. The (false) joint is stabilised by the following ligaments, among others:

• Ligamentum tibiofibulare anterius
• Posterior tibiofibular ligament
