The only movements permitted in the joints of the digits are flexion and extension; these movements are more extensive between the first and second phalanges than between the second and third. The flexor hallucis longus and flexor digitorum longus flex the interphalangeal joint of the big toe and lateral four toes, respectively. The tendons of ...
The metatarsophalangeal joints (MTP joints) are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes. They are analogous to the knuckles of the hand , and are consequently known as toe knuckles in common speech.
In anatomy, pronation is a rotational movement of the forearm (at the radioulnar joint) or foot (at the subtalar and talocalcaneonavicular joints). Pronation of the foot refers to how the body distributes weight as it cycles through the gait. During the gait cycle the foot can pronate in many different ways based on rearfoot and forefoot function.
The tarsometatarsal joints (Lisfranc joints) are arthrodial joints in the foot. The tarsometatarsal joints involve the first, second and third cuneiform bones, the cuboid bone and the metatarsal bones. The eponym of Lisfranc joint is 18th–19th-century surgeon and gynecologist Jacques Lisfranc de St. Martin. [1]
Along with the transverse tarsal joint (i.e. talonavicular and calcaneocuboid joint), the subtalar joint transforms tibial rotation into forefoot supination and pronation. The axis of rotation in the joint is directed upward 42 degrees from the horizontal plane and 16 degrees medially from the midline of the foot.
The intertarsal joint are the joints of the tarsal bones in the foot. There are six specific inter tarsal joints (articulations) in the human foot: Subtalar joint;
The intermetatarsal joints are the articulations between the base of metatarsal bones. The base of the first metatarsal is not connected with that of the second by any ligaments; in this respect the great toe resembles the thumb. The bases of the other four metatarsals are connected by the dorsal, plantar, and interosseous ligaments.
In human anatomy, the subtalar joint, also known as the talocalcaneal joint, is a joint of the foot. It occurs at the meeting point of the talus and the calcaneus . The joint is classed structurally as a synovial joint , [ 1 ] and functionally as a plane joint .
