The annular ligaments of the toes are the annular part of the fibrous sheathes of the toes. These strong transverse bands of fibrous tissue cross the flexor tendons at the level of the upper half of the proximal phalanges of the foot .
The flexor retinaculum of the foot extends from the medial malleolus above, to the calcaneus below. [1] This converts a series of bony grooves into canals for the passage of the tendons of the flexor muscles and the posterior tibial vessels and tibial nerve into the sole of the foot, known as the tarsal tunnel.
The inferior extensor retinaculum of the foot (cruciate crural ligament, lower part of anterior annular ligament) is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for the interosseous talocalcaneal ligament; it is directed medialward as a double layer, one lamina passing in front ...
Annular ligament may refer to: Annular ligament of femur; Annular ligaments of fingers; Annular ligament of radius; Annular ligament of stapes (also known as the ...
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.
The A2 and A4 pulleys arise from the periosteum on the proximal half of the proximal phalanx and the mid portion of the middle phalanx, respectively. [1] The first annular pulley (A1 pulley), near the head of the metacarpal bone, lies in the flexor groove in the deep transverse metacarpal ligament. [2]
The plantar ligaments consist of longitudinal and oblique bands, disposed with less regularity than the dorsal ligaments. Those for the first and second metatarsals are the strongest; the second and third metatarsals are joined by oblique bands to the first cuneiform; the fourth and fifth metatarsals are connected by a few fibers to the cuboid.
Plantar ligament refer to ligaments in the sole of the foot: Plantar plates, fibrocartilaginous structures in the metatarsophalangeal and interphalangeal joints of the toes. One of several tarsal, metatarsal, and tarsometatarsal ligaments: Long plantar ligament, that connects the calcaneus with the cuboid bone
