What is the Calcaneonavicular joint?
What is the Calcaneonavicular joint?
As the name suggests, the talocalcaneonavicular joint is a synovial ball and socket joint formed between three tarsal bones (talus, calcaneus and navicular) and the adjacent ligamentous structures. There are five articular facets on the talus that participate in the formation of this joint.
What does Talocrural joint mean?
The ankle joint, also known as the talocrural joint, is a synovial joint that connects the bones of the leg, the fibula and tibia, with the talus of the foot. It is a complex hinge joint composed of two articulations.
What 3 bones make up the subtalar joint?
The talus and calcaneus articulation is referred to as the subtalar joint, which has three facets on each of the talus and calcaneus. Midfoot: The midfoot is made up of five of the seven tarsal bones: navicular, cuboid, and medial, middle, and lateral cuneiforms.
Where is talocalcaneonavicular joint located?
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 is calcaneocuboid joint?
The calcaneocuboid articulation is the joint between the calcaneus and the cuboid bone.
What is the Naviculocuneiform joint?
The naviculocuneiform (NC) joint is located in the middle of the foot. It consists of four bones: the tarsal navicular and the medial, middle, and lateral cuneiforms. The main reason to perform NC joint fusion is to relieve pain related to arthritis.
Where is the Talocrural joint?
The talocrural joint is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The articulation between the tibia and the talus bears more weight than that between the smaller fibula and the talus.
What is a Trochoid joint?
pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament.
What is a subtalar joint?
Subtalar joint is made up of articulation between three joint surfaces inferiorly talus with three joint surfaces superiorly calcaneus (Fig. 23.14) (Drake et al., 2015; Bartonicek et al., 2018). Subtalar joint functions as a bridge between foot and ankle; transferring loads from foot to tibia or from tibia to foot.
How many subtalar joints are there?
three
The subtalar joint (talocalcaneal joint) is anatomically described as the articulation formed between posterior articular surfaces of two tarsal bones; the talus and calcaneus….Subtalar joint.
| Type | Plane synovial joint; three degrees of freedom |
|---|---|
| Blood supply | Posterior tibial artery, fibular artery |
What type of joint is the calcaneocuboid?
saddle-type joint
The calcaneocuboid joint involves the anterior surface of the calcaneus and the posterior surface of the cuboid. Its joint capsule is thickened superiorly and also inferiorly 1. It is a modified saddle-type joint.
What is the Midtarsal joint?
The midtarsal joint (MTJt) consists of the combined articulations of the talonavicular and calcaneocuboid joints and represents the functional articulation between the rearfoot (talus and calcaneus) and the midfoot (navicular and cuboid).
