The transverse metatarsal ligament is a narrow band which runs across and connects together the heads of all the metatarsal bones. It is blended anteriorly with the plantar (glenoid) ligaments of the metatarsophalangeal articulations. Its plantar surface is concave where the Flexor tendons run below it.
The transverse arch is composed of the three cuneiforms, the cuboid, and the five metatarsal bases. The transverse arch is strengthened by the interosseous, plantar, and dorsal ligaments, by the short muscles of the first and fifth toes (especially the transverse head of the adductor hallucis), and by the fibularis longus, whose tendon ...
The dorsal ligaments are strong, flat bands.. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
They are condyloid joints, meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges). The region of skin directly below the joints forms the ball of the foot. The ligaments are the plantar and two collateral.
A transverse system at the MTP joints is formed by the plantar plates and the deep transverse metatarsal ligament. The strong, longitudinal fibres of the deep plantar fascia are inserted along this transverse system to form a strong longitudinal system. The longitudinal system controls the longitudinal arches of the foot, whilst the transverse ...
The two heads of each muscle form a central tendon which passes forwards deep to the deep transverse metatarsal ligament. [1] The tendons are inserted on the bases of the second, third, and fourth proximal phalanges [2] and into the aponeurosis of the tendons of the extensor digitorum longus [3] without attaching to the extensor hoods of the toes.
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.
The transverse tarsal joint or midtarsal joint or Chopart's joint is formed by the articulation of the calcaneus with the cuboid (the calcaneocuboid joint), and the articulation of the talus with the navicular (the talocalcaneonavicular joint).
