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 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.
The dorsal ligaments pass transversely between the dorsal surfaces of the bases of the adjacent metatarsal bones. The plantar ligaments have a similar arrangement to the dorsal. The interosseous ligaments consist of strong transverse fibers which connect the rough non-articular portions of the adjacent surfaces.
Distally, the plantar fascia becomes continuous with the fibrous sheaths enveloping the flexor tendons passing to the toes. At the anterior extremity of the sole - inferior to the heads of the metatarsal bones - the plantar aponeurosis forms the superficial transverse metatarsal ligament. [2]
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 ...
Neurectomy may be performed using one of two general methods. Making the incision from the dorsal side (the top of the foot) is the more common method but requires cutting the deep transverse metatarsal ligament that connects the third and fourth metatarsals in order to access the nerve beneath it.
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.
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 ...
