The foot joints
Composed by different articular surfaces, the foot joints include the tarsals, metatarsals, and phalanges. With the help of the ligaments, in minor or major ways, these bones interact with each other´s producing diverse range of movements.
Movements.The foot joints include a wide range of movements, such as:
- Flexion.
- Extension.
- Inversion.
- Eversion.
- Pronation.
- Supination.
- Abduction.
- Adduction.
Of the tarsal joints, the most important ones include the talocalcaneal, talocalcaneonavicular, and calcaneocuboid joints, existing other joints that include smaller tarsal bones.
The talocalcaneal joint.
It is formed by the articular surfaces of the talus and calcaneus, between the posterior calcaneal facet of the inferior surface and the posterior talar facet of the superior surface, respectively. Enclosed by a synovial membrane and covered by a fibrous membrane, this joint is reinforced by the lateral, medial, posterior, and interosseous talocalcaneal ligaments.
