What type of joint is the talocalcaneonavicular joint?
What type of joint is the talocalcaneonavicular joint?
ball and socket joint
The talocalcaneonavicular joint is a ball and socket joint; the rounded head of the talus is received into the concavity formed by the posterior surface of the navicular, the anterior articular surface of the calcaneus, and the upper surface of the plantar calcaneonavicular ligament.
What movements occur at the talocalcaneonavicular joint?
In the talocalcaneonavicular joint, the two types of movements (gliding and rotation) allow motions in 3 degrees of freedom: inversion/eversion, abduction/adduction, plantarflexion/dorsiflexion.
Is talonavicular joint same as talocalcaneonavicular joint?
Gross anatomy The talonavicular joint and the anterior part of the talocalcaneal joint are collectively known as the talocalcaneonavicular joint and may share the same joint space.
What are the 3 tarsal joints?
Restrictions primarily involve Lisfranc’s joint, the second and third metatarsophalangeal joints, the talocrural joint and, to a lesser extent, the talocalcaneonavicular and subtalar joints. The main TrPs are found in the deep flexors of the sole of the foot and dorsally between the metatarsal bones.
What is the talus?
Overview. The talus is a small bone that sits between the heel bone (calcaneus) and the two bones of the lower leg (the tibia and fibula). It has an irregular, humped shape like a turtle’s shell. The bones of the lower leg ride on top and around the sides to form the ankle joint.
What is a talonavicular joint?
The talonavicular joint is the universal joint of the foot, allowing rotation, sideways movement and up / down motion at the midfoot. It is involved in the flexibility and movements of the foot particularly on uneven ground, whereas most of the up / down movements occur at the ankle above.
Which ligaments attach to talus?
On the lateral side, the joint is held together by the posterior talofibular and anterior talofibular ligaments. On the medial side it is held together by a massive ligament, the deltoid ligament, which attaches not only to a broad area on the talus but also to the adjoining bones below and in front.
What type of bone is talus?
The talus is the second largest of the tarsal bones; it is also one of the bones in the human body with the highest percentage of its surface area covered by articular cartilage….

Where is the malleolus found?
The bony knobs on the inside and outside of the ankle are called the malleoli, which is the plural form of malleolus. The knob on the outside of the ankle, the lateral malleolus, is the end of the fibula, the smaller bone in the lower leg.
Is the talonavicular joint a ball and socket?
Consequently, we can visualize the TCN as a ball and socket joint where the large convexity of the head of the talus is received by a large ‘socket’ formed by the concavity of the navicular, the concavities of the anterior and medial calcaneal facets, by the plantar calcaneonavicular ligament and by the deltoid …
