Joints of the Foot: Talocalcaneal – Joints of Lower Limb

00:01 the ankle joint. Now, let’s have a look at the joints of the foot. Look at the talocalcaneal joint. This is an important joint between the talus superiorly and the calcaneus inferiorly.

00:12 Here, we can see we have the subtalar joint, and we have the talocalcaneonavicular joint, a whole series of joints which are sitting within the foot. We’re just going to concentrate on the talocalcaneal foot. The joints of the foot involve the tarsals, metatarsals, and phalanges.

00:34 And this important joint, the talocalcaneal joint, also known as the subtalar joint, which we can just see here. So this is going to be calcaneus and that’s going to articulate with the talus here - subtalar because it’s below the talus. The talus articulates with the calcaneus at this joint and it has a weak joint capsule reinforced by the strong interosseous talocalcaneal ligaments. And here we can see some strong talocalcaneal ligament running from the talus to the calcaneal bone. We also have the transverse tarsal joint.

01:15 So here, we can see the transverse tarsal joint, and that is running consisting of the talocalcaneonavicular and the calcaneocuboid joints. So we have a whole series of joints that are running transversely across the tarsal joint. We have the talocalcaneonavicular joint. We see that running here and here between the talus, the calcaneus, and the navicular bones, and this also is supported by a number of interconnecting ligaments. And the ligaments are determined by the names on the bone. Here, we can see we have the talocalcaneonavicular joint.
