Ankle Monitor
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" (without qualifiers) can refer broadly to the region or specifically to the talocrural joint. The main bones of the ankle region are the talus (in the foot), and the tibia and fibula (in the leg). 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. Structure Region The ankle region is found at the junction of the leg and the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foot
The foot ( : feet) 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 or nails. Etymology The word "foot", in the sense of meaning the "terminal part of the leg of a vertebrate animal" comes from "Old English fot "foot," from Proto-Germanic *fot (source also of Old Frisian fot, Old Saxon fot, Old Norse fotr, Danish fod, Swedish fot, Dutch voet, Old High German fuoz, German Fuß, Gothic fotus "foot"), from PIE root *ped- "foot". The "plural form feet is an instance of i-mutation." Structure The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments.Podiatry Channel, ''Anatomy of the foot and ankle'' The joints of the ...

Lateral Malleolus
A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia. The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word ''malleolus'' (), plural ''malleoli'' (), comes from Latin and means "small hammer". (It is cognate with '' mallet''.) Medial malleolus The medial malleolus is found at the foot end of the tibia. The medial surface of the lower extremity of tibia is prolonged downward to form a strong pyramidal process, flattened from without inward - the medial malleolus. * The ''medial surface'' of this process is convex and subcutaneous. * The ''lateral'' or ''articular surface'' is smooth and slightly concave, and articulates with the talus. * The ''anterior ...

Syndesmosis
In anatomy, fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull the joints between the bones are called sutures. Such immovable joints are also referred to as synarthroses. Types Most fibrous joints are also called "fixed" or "immovable". These joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called '' sutures''. In fetal skulls the sutures are wide to allow slight movement during birth. They later become rigid ( synarthrodial). Some of the long bones in the body such as the radius and ulna in the forearm are joined by a ''syndesmosis'' (along the interosseous membrane). Syndemoses are slightly moveable ( amphiarthrodial). The distal tibiofibular joint is another example. A ''gomphosis'' is a joint between the root of a tooth and the socket in the maxil ...

Navicular Tuberosity
The navicular bone is a small bone found in the feet of most mammals. Human anatomy The navicular bone in humans is one of the tarsal bones, found in the foot. Its name derives from the human bone's resemblance to a small boat, caused by the strongly concave proximal articular surface. The term ''navicular bone'' or ''hand navicular bone'' was formerly used for the scaphoid bone, one of the carpal bones of the wrist. The navicular bone in humans is located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid. It is the last of the foot bones to start ossification and does not tend to do so until the end of the third year in girls and the beginning of the fourth year in boys, although a large range of variation has been reported. The tibialis posterior is the only muscle that attaches to the navicular bone. The main portion of the muscle inserts into the tuberosity of the navi ...

Calcaneonavicular Ligament
The plantar calcaneonavicular ligament (also known as the spring ligament or spring ligament complex) is a complex of three ligaments on the underside of the foot that connect the calcaneus with the navicular bone. Structure The plantar calcaneonavicular ligamentous complex is a broad and thick band with three constituent ligaments. These connect the anterior margin of the sustentaculum tali of the calcaneus to the plantar surface of the navicular bone. Its individual components are the: * superomedial calcaneonavicular ligament. * medioplantar oblique ligament. * inferior calcaneonavicular ligament. These ligament components attach to different parts of the navicular bone. The dorsal or superomedial component of the ligament presents a fibrocartilaginous facet, lined by the synovial membrane, upon which a portion of the head of the talus rests. Its plantar surface, consisting of the intermedial and lateral ligaments, is supported by the tendon of the tibialis posterior; its me ...

Calcaneus
In humans and many other primates, the calcaneus (; from the Latin ''calcaneus'' or ''calcaneum'', meaning heel) 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. Structure In humans, the calcaneus is the largest of the tarsal bones and the largest bone of the foot. Its long axis is pointed forwards and laterally. The talus bone, calcaneus, and navicular bone are considered the proximal row of tarsal bones. In the calcaneus, several important structures can be distinguished:Platzer (2004), p 216 There is a large calcaneal tuberosity located posteriorly on plantar surface with medial and lateral tubercles on its surface. Besides, there is another peroneal tubecle on its lateral surface. On its lower edge on either side are its lateral and medial processes (serving as the origins of the abductor hallucis and abductor digiti minimi). The Achilles tendon is inserted into a roughened area on its superio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Talar Shelf
Talar դալար is a Western Armenian name for females. It's meaning is symbolic of the Evergreen Tree. The talar or talaar ( fa, تالار) is the throne hall of the Persian monarch that is open to the public. It includes a throne carved on the rock-cut tomb of Darius at Naqsh-e Rostam, near Persepolis, and above the portico which was copied from his palace. The ''Talar Divan Khaneh'' built by Fath Ali Shah is an example of this pavilion. Description In ancient times, as depicted in the sculptured facade of Darius tomb at Persepolis show, the talar had three tiers, with Atlant statues upholding each. This design typified the subject-people of the monarch. The talar built by the Qajar dynasty as part of the Royal Palace is a spacious chamber with flat ceiling decorated with mirror panels. The walls are also decorated with mirror work called ''aineh-kari'', which produced numerous angles and coruscations. See also *Architecture of Iran Iranian architecture or Persi ...

Calcaneofibular Ligament
The calcaneofibular ligament is a narrow, rounded cord, running from the tip of the lateral malleolus of the fibula downward and slightly backward to a tubercle on the lateral surface of the calcaneus. It is part of the lateral collateral ligament, which opposes the hyperinversion of the subtalar joint, as in a common type of ankle sprain. It is covered by the tendons of the fibularis longus and brevis muscles. Clinical significance The calcaneofibular ligament is commonly sprained ligament in ankle injuries. It may be injured individually, or in combination with other ligaments such as the anterior talofibular ligament and the posterior talofibular ligament The posterior talofibular ligament is a ligament that connects the fibula to the talus bone. It runs almost horizontally from the malleolar fossa of the lateral malleolus of the fibula The fibula or calf bone is a leg bone on the lateral side ....

Posterior Talofibular Ligament
The posterior talofibular ligament is a ligament that connects the fibula to the talus bone. It runs almost horizontally from the malleolar fossa of the lateral malleolus of the fibula to the lateral tubercle on the posterior surface of the talus. This insertion lies immediately lateral to the groove for the tendon of the flexor hallucis longus The flexor hallucis longus muscle (FHL) is one of the three deep muscles of the posterior compartment of the leg that attaches to the plantar surface of the distal phalanx of the great toe. The other deep muscles are the flexor digitorum longus an .... References External links * () Ligaments of the lower limb {{ligament-stub ...

Anterior Talofibular Ligament
The anterior talofibular ligament is a ligament in the ankle. It passes from the anterior margin of the fibular malleolus, anteriorly and laterally, to the talus bone, in front of its lateral articular facet. It is one of the lateral ligaments of the ankle and prevents the foot from sliding forward in relation to the shin. It is the most commonly injured ligament in a sprained ankle—from an inversion injury—and will allow a positive anterior drawer test of the ankle if completely torn. See also * Sprained ankle * Posterior talofibular ligament The posterior talofibular ligament is a ligament that connects the fibula to the talus bone.

Deltoid Ligament
The deltoid ligament (or medial ligament of talocrural joint) is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus. The deltoid ligament is composed of 4 fibers: 1. Anterior tibiotalar ligament 2. Tibiocalcaneal ligament 3. Posterior tibiotalar ligament 4. Tibionavicular ligament. It consists of two sets of fibers, superficial and deep. Superficial fibres Of the superficial fibres, * ''tibionavicular'' pass forward to be inserted into the tuberosity of the navicular bone, and immediately behind this they blend with the medial margin of the plantar calcaneonavicular ligament; * ''tibiocalcaneal'' descend almost perpendicularly to be inserted into the whole length of the sustentaculum tali of the calcaneus; * ''posterior tibiotalar'' from the posterior colliculus of the medial malleolus to the posteromedial surface of the talus Deep fibres The deep fibres (''anterior tibiotalar'') are attached from the anterio ...

Osteoarthritis
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone which affects 1 in 7 adults in the United States. It is believed to be the fourth leading cause of disability in the world. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Initially they may occur only after exercise but can become constant over time. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs; the knee and hip joints; and the joints of the neck and lower back. Joints on one side of the body are often more affected than those on the other. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
