The calcaneocuboid joint is the joint between the calcaneus and the cuboid bone.
The calcaneocuboid joint is a type of saddle joint between the calcaneus and the cuboid bone. [1]
There are five ligaments connecting the calcaneus and the cuboid bone, forming parts of the articular capsule:
The calcaneocuboid joint is conventionally described as among the least mobile joints in the human foot. The articular surfaces of the two bones are relatively flat with some irregular undulations, which seem to suggest movement limited to a single rotation and some translation. However, the cuboid rotates as much as 25° about an oblique axis during inversion-eversion in a movement that could be called involution. [3]
The calcaneocuboid joint may be affected by a calcaneal fracture. [4] This may be a sign of a worse fracture, associated with worse outcomes (such as osteoarthritis) after treatment. [4]
The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
In the human body, the cuboid bone is one of the seven tarsal bones of the foot.
The metatarsal bones, or metatarsus, are a group of five long bones in the midfoot, located between the tarsal bones and the phalanges (toes). Lacking individual names, the metatarsal bones are numbered from the medial side : the first, second, third, fourth, and fifth metatarsal. The metatarsals are analogous to the metacarpal bones of the hand. The lengths of the metatarsal bones in humans are, in descending order, second, third, fourth, fifth, and first. A bovine hind leg has two metatarsals.
The ankle, or the talocrural region, or the jumping bone (informal) is the area where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. The movements produced at this joint are dorsiflexion and plantarflexion of the foot. In common usage, the term ankle refers exclusively to the ankle region. In medical terminology, "ankle" can refer broadly to the region or specifically to the talocrural joint.
The Achilles tendon or heel cord, also known as the calcaneal tendon, is a tendon at the back of the lower leg, and is the thickest in the human body. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone. These muscles, acting via the tendon, cause plantar flexion of the foot at the ankle joint, and flexion at the knee.
In humans and many other primates, the calcaneus or heel bone is a bone of the tarsus of the foot which constitutes the heel. In some other animals, it is the point of the hock.
Plantar fasciitis or plantar heel pain is a disorder of the plantar fascia, which is the connective tissue which supports the arch of the foot. It results in pain in the heel and bottom of the foot that is usually most severe with the first steps of the day or following a period of rest. Pain is also frequently brought on by bending the foot and toes up towards the shin. The pain typically comes on gradually, and it affects both feet in about one-third of cases.
The talus, talus bone, astragalus, or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot.
Flexor hallucis brevis muscle is a muscle of the foot that flexes the big toe.
A calcaneal spur is a bony outgrowth from the calcaneal tuberosity. Calcaneal spurs are typically detected by x-ray examination. It is a form of exostosis.
The long plantar ligament is a long ligament on the underside of the foot that connects the calcaneus with the 2nd to 5th metatarsal.
The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight.
The plantar calcaneocuboid ligament is a ligament on the bottom of the foot that connects the calcaneus to the cuboid bone. It lies deep to the long plantar ligament.
The plantar calcaneonavicular ligament is a complex of three ligaments on the underside of the foot that connect the calcaneus with the navicular bone.
The Lisfranc ligament is one of several ligaments which connects the medial cuneiform bone to the second metatarsal. Sometimes, the term Lisfranc ligament refers specifically to the ligament that connects the superior, lateral surface of the medial cuneiform to the superior, medial surface of the base of the second metatarsal.
The fifth metatarsal bone is a long bone in the foot, and is palpable along the distal outer edges of the feet. It is the second smallest of the five metatarsal bones. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand.
A calcaneal fracture is a break of the calcaneus. Symptoms may include pain, bruising, trouble walking, and deformity of the heel. It may be associated with breaks of the hip or back.
Cuboid syndrome or cuboid subluxation describes a condition that results from subtle injury to the calcaneocuboid joint and ligaments in the vicinity of the cuboid bone, one of seven tarsal bones of the human foot.
The calcaneal pitch is an angle used mainly in the diagnosis and severity grading of flat feet and pes cavus.
The sinus tarsi, also known as the talocalcaneal sulcus, is a cylindrical canal in the hindfoot. It has a complex anatomy, with five ligamentous structures and a pad of adipose tissue (fat). The tarsal canal opens up into the sinus tarsi, however, the tarsal canal is a distinct structure.
