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).
What is the calcaneocuboid joint reinforced by?
The calcaneocuboid joint is formed by the quadrilateral facets of the calcaneus and cuboid bones and its capsule, which is reinforced by ligaments [1].
What bones make up the calcaneocuboid joint?
The navicular, cuboid, and medal, middle, and lateral cuneiforms make up the midfoot. The cuboid lays on the outside (lateral side) of the foot and articulates with the calcaneus bone to form the calcaneocuboid joint.
What is Tarsometatarsal?
The tarsometatarsal joints are composed of the articulations between the bases of the metatarsals and the distal surfaces of the three cuneiforms and the cuboid (Fig. 11.21). Marking the junction between the midfoot and the forefoot, these joints serve as the base joints for the rays of the foot.
What is a Midtarsal amputation?
Medical Definition of midtarsal amputation : amputation of the forepart of the foot through the midtarsal joint.
What is a forefoot?
The forefoot consists of your toe bones, called phalanges, and metatarsal bones, the long bones in your feet. Phalanges connect to metatarsals at the ball of the foot by joints called phalange metatarsal joints.
What is Calcaneocuboid articulation?
The calcaneocuboid articulation is the joint between the calcaneus and the cuboid bone. The ligaments connecting the calcaneus with the cuboid are five in number: … part of the bifurcated ligament, the long plantar ligament, and the plantar calcaneocuboid ligament.
Where is the calcaneocuboid?
Calcaneocuboid arthritis is a form of osteoarthritis which affects the calcaneocuboid joint, that is located between the cuboid bone and the heel bone. Located on the outside of the foot, in front of the heel bone, the cuboid bone is characterised by its cube shape.
Which of the following joints consists of the calcaneocuboid and the Talonavicular joints?
The transverse tarsal joint separates the rearfoot from the midfoot (see Fig. 11.1). This extensive joint consists of two separate articulations: the talonavicular joint and the calcaneocuboid joint. This pair of joints allows the midfoot to move independently of the rearfoot (i.e., the calcaneus and talus).
Do big toes have knuckles?
Each big toe has two joints: Metatarsophalangeal joint. Interphalangeal joint.
What are Intercarpal joints?
The intercarpal joints (joints of the carpal bones of the wrist) can be subdivided into three sets of joints (also called articulations): Those of the proximal row of carpal bones, those of the distal row of carpal bones, and those of the two rows with each other.
What are the joints of the hand?
The joints in the hand are joints found at the distal end of the upper limb. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus. Between the carpal bones are the intercarpal articulations and the midcarpal joint. … Joints of hand.

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.
Why does my Tarsometatarsal hurt?
Tarsometatarsal (TMT) arthritis is characterized by midfoot instability, pain, and severe functional impairment. The most common cause is post-traumatic arthritis, followed by primary osteoarthritis and other inflammatory processes.
How do you treat a Tarsometatarsal joint?
Treatments. If there are no fractures involved in the injury, no ligaments are torn and there are no dislocations, treatment may be as simple as a cast on the foot for six weeks or more. 4 Crutches will help the patient get around and keep weight and pressure off of the injured foot.
What is Transmetacarpal amputation?
Transmetatarsal amputation (TMA) surgically removes a part of the foot that includes the metatarsals, which is used to treat a severely infected foot or a foot with lack of oxygen supply.
What is a transtibial amputation?
Transtibial amputation, or below-knee amputation, is a surgical procedure performed to remove the lower limb below the knee when that limb has been severely damaged or is diseased. Most transtibial amputations (60%70%) are due to peripheral vascular disease, or disease of the circulation in the lower limb.
What is a Boyd amputation?
The Boyd amputation is a surgical technique used to treat osteomyelitis of the foot. This amputation is a technically more difficult procedure to perform than the Syme amputation, but it offers certain advantages. The Boyd amputation provides a more solid stump because it preserves the function of the plantar heel pad.
What is the midfoot?
The midfoot is the middle region of the foot, where a cluster of small bones forms an arch on the top of the foot. From this cluster, five long bones (metatarsals) extend to the toes. The bones are held in place by connective tissues (ligaments) that stretch both across and down the foot.
What is neuroma?
A neuroma is a benign tumor of a nerve. Morton’s neuroma is not actually a tumor, but a thickening of the tissue that surrounds the digital nerve leading to the toes.
What is right forefoot?
The forefoot is one of the three primary regions of the foot, in addition to the midfoot and the rearfoot (or hindfoot). It is composed of tendons, ligaments, soft tissue, and 19 bones in five toes, also known as the phalanges.
Why is arthrodesis performed?
Bone or joint fusion surgery, called arthrodesis, is performed to relieve arthritis pain in the ankles, wrists, fingers, thumbs, or spine. In arthrodesis, two bones on each end of a joint are fused, eliminating the joint itself and making one continuous bone. This surgery is typically quite successful.
Can you get arthritis in your cuboid bone?
Classically midfoot arthritis describes arthritis at the level of the Lisfranc joint but can involve arthritis between the cuneiform and the cuboid and navicular bones.
What is the extra bone in your ankle called?
What Is the Os Trigonum? The os trigonum is an extra (accessory) bone that sometimes develops behind the ankle bone (talus). It is connected to the talus by a fibrous band.
What is the heel called?
calcaneus The calcaneus (heel bone) is the largest of the tarsal bones in the foot. It lies at the back of the foot (hindfoot) below the three bones that make up the ankle joint.
How do you get cuboid syndrome?
Cuboid syndrome can result from foot injuries like twisting your ankle by falling, misstepping, or doing other activities that put intense strain on your ankle bones and ligaments. Cuboid syndrome can also result from overuse or repetitive strain to your foot.
Do humans have a navicular bone?
The navicular bone is one of the 26 bones in the human foot. It’s important for connecting the ankle to the lower bones in our feet and helps form the arch that enables us to walk.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
