Cuboid Bone
In the human body, the cuboid bone is one of the seven tarsal bones of the foot. Structure The cuboid bone is the most lateral of the bones in the distal row of the tarsus. It is roughly cubical in shape, and presents a prominence in its inferior (or plantar) surface, the tuberosity of the cuboid. The bone provides a groove where the tendon of the peroneus longus muscle passes to reach its insertion in the first metatarsal and medial cuneiform bones. Surfaces The dorsal surface, directed upward and lateralward, is rough, for the attachment of ligaments. The plantar surface presents in front a deep groove, the peroneal sulcus, which runs obliquely forward and medialward; it lodges the tendon of the peroneus longus, and is bounded behind by a prominent ridge, to which the long plantar ligament is attached. The ridge ends laterally in an eminence, the tuberosity, the surface of which presents an oval facet; on this facet glides the sesamoid bone or cartilage frequently found ...

Calcaneocuboid Articulation
The calcaneocuboid joint is the joint between the calcaneus and the cuboid bone. Structure The calcaneocuboid joint is a type of saddle joint between the calcaneus and the cuboid bone. Ligaments There are five ligaments connecting the calcaneus and the cuboid bone, forming parts of the articular capsule: * the dorsal calcaneocuboid ligament. * part of the bifurcated ligament. * the long plantar ligament. * and the plantar calcaneocuboid ligament. Function 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. Clinical significance The calcaneocuboid joint may be affected by a calcaneal fracture. This may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Calcaneus
In humans and many other primates, the calcaneus (; from the Latin ''calcaneus'' or ''calcaneum'', meaning heel; : calcanei or calcanea) or heel bone is a bone of the Tarsus (skeleton), tarsus of the foot which constitutes the heel. In some other animals, it is the point of the hock (anatomy), 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 tubercle 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 muscle, abductor hallucis and Abductor di ...

Bones Of The Lower Limb
A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple functions. Bone tissue (osseous tissue), which is also called bone in the uncountable sense of that word, is hard tissue, a type of specialised connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralisation of bone; osteoclasts are involved in the resorption of bone tissue. Modified (flattened) osteoblasts become the lining cells that form a protective layer on the bone surface. The mineralised ma ...

Terms For Anatomical Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek language, Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes, axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. ...

Nutcracker Fracture
Nutcracker fracture refers to the comminuted fracture of the cuboid bone In the human body, the cuboid bone is one of the seven tarsal bones of the foot. Structure The cuboid bone is the most lateral of the bones in the distal row of the tarsus. It is roughly cubical in shape, and presents a prominence in its infer ... of the foot. If treated improperly, it can lead to lateral column shortening and significant pain. Nutcracker fracture is rare because of the relatively protected position of cuboid in the midfoot.

Knucklebones
Knucklebones, also known as scatter jacks, snobs, astragaloi (''singular'': astragalus), tali, dibs, fivestones, jacks, jackstones, or jinks, among many other names, is a game of Fine motor skill, dexterity played with a number of small objects that are thrown up, caught, and manipulated in various manners. It is ancient in origin and is found in various cultures worldwide. The name "knucklebones" is derived from the Ancient Greece, Ancient Greek version of the game, which uses the Talus bone, astragalus (a bone in the ankle, or hock (anatomy), hock) of a sheep. However, different variants of the game from various cultures use other objects, including stones, seashells, seeds, and cubes. Modern knucklebones consist of six points, or knobs, projecting from a common base and are usually made of metal or plastic. The winner is the first player to successfully complete a prescribed series of throws, which, though similar, differ widely in detail. The simplest throw consists in ei ...

Cuboid Fracture
A cuboid fracture is a Bone fracture, fracture of the cuboid bone of the foot. Diagnosis is by Projectional radiography, X-ray imaging, magnetic resonance imaging, or Bone scintigraphy, bone scan. Treatment may be Conservative management, conservative or involve surgery, depending on the type of fracture. They are rare. If the cuboid bone is broken, then it is common for other bones in the foot to be broken or dislocated as well. Cuboid fractures are associated with Lisfranc injury, Lisfranc injuries.

Cuboid Syndrome
Cuboid syndrome or cuboid subluxation is 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. This condition often manifests in the form of lateral (little toe side) foot pain and sometimes general foot weakness. Cuboid syndrome, which is relatively common but not well defined or recognized, is known by many other names, including lateral plantar neuritis, cuboid fault syndrome, peroneal cuboid syndrome, dropped cuboid, locked cuboid and subluxed cuboid. Signs and symptoms A patient with cuboid syndrome usually seeks medical advice and attention complaining of pain, discomfort, or weakness along the lateral aspect of the foot between the fourth and fifth metatarsals and the calcaneocuboid joint. The pain may radiate throughout the foot. Tenderness may be elicited over the tendon of the peroneus longus muscle and an antalgic gait may be observed. The pain may be observ ...

Tibialis Posterior Muscle
The tibialis posterior muscle is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg. It is the key stabilizing muscle of the lower leg. Posterior tibial tendonitis Posterior tibial tendonitis is a condition that predominantly affects runners and active individuals. It involves inflammation or tearing of the posterior tibial tendon, which connects the calf muscle to the bones on the inside of the foot. It plays a vital role in supporting the arch and assisting in foot movement. This condition can cause pain, swelling, and potentially lead to flatfoot if left untreated. Structure The tibialis posterior muscle originates on the inner posterior border of the fibula laterally. It is also attached to the interosseous membrane medially, which attaches to the tibia and fibula. The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus. It terminates by dividin ...

Navicular Bone
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 tarsus (skeleton), tarsal bones, found in the foot. Its name derives from the human bone's resemblance to a small boat, caused by the strongly concave Anatomical terms of location#Proximal and distal, proximal joint, articular surface. The term ''navicular bone'' or ''hand navicular bone'' was formerly used for the scaphoid bone, one of the Carpal bones, carpal bones of the wrist. The navicular bone in humans is located on the Anatomical terms of location#Relative directions, medial side of the foot, and articulates proximally with the Talus bone, talus, Anatomical terms of location#Relative directions, distally with the three cuneiform bones, and Anatomical terms of location#Relative directions, laterally with the Cuboid bone, 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 ...

Lateral Cuneiform Bone
There are three cuneiform ("wedge-shaped") bones in the human foot: * the first or medial cuneiform * the second or intermediate cuneiform, also known as the middle cuneiform * the third or lateral cuneiform They are located between the navicular bone and the first, second and third metatarsal bones and are medial to the cuboid bone. Structure There are three cuneiform bones: # The medial cuneiform (also known as first cuneiform) is the largest of the cuneiforms. It is situated at the medial side of the foot, anterior to the navicular bone and posterior to the base of the first metatarsal. Lateral to it is the intermediate cuneiform. It articulates with four bones: the navicular, second cuneiform, and first and second metatarsals. The tibialis anterior and fibularis longus muscle inserts at the medial cuneiform bone. # The intermediate cuneiform (second cuneiform or middle cuneiform) is shaped like a wedge, the thin end pointing downwards. The intermediate cuneiform is situate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
