What Is Talocrural Joint Movement?


Quick Answer

The talocrural joint is another name for one of the joints in the human ankle, and movement of this joint is called talocrural movement. This particular joint, which is one of the three joints in the ankle, is capable of dorsiflexion movement and plantarflexion movement. According to Sportsinjuryclinic.net, the talocrural joint is made from the junction of the distal ends of the tibia and fibula and the talus.

Manatomy.com notes that dorsiflexion movement occurs when the toes are pointed upwards. Such movements rely on the action of four muscles: the tibialis anterior, extensor hallusic longus, extensor digitorum longus and the peroneus tertius. The Achilles tendon, medial ligament and calcaneofibular ligament prevent the foot from flexing too far in this direction. By contrast, plantarflexion movement requires the gastrocnemius, soleus, plantaris, peroneus longus, peroneus brevis, tibialis posterior, flexor digitorum longus and flexor hallucis longus muscles.

According to Manatomy.com, because more muscles are involved in plantarflexion movement than in dorsiflexion movement, the former is a much more powerful movement than the latter. Because the bones of the joint fit together very tightly and there are many different ligaments attached to it, the joint is very strong. Additionally, it is quite stable, which allows it to support a person’s weight.
