Medial collateral ligament: aka Deltoid Ligament A strong, flat, triangular band. Deltoid Ligament is much stronger than lateral collateral. Function: Resists Eversion of the Ankle joint
The least mobile joints in the human foot. The articular surfaces of the two bones are relatively flat with some irregular undulations, limiting movement to a single rotation and some translation. (which occur when the foot is inverting or everting)
The Intertarsal articulations are the joints between the Tarsal bones in the foot. 1.Intercuneiform articulations 2.Cuneocuboid articulation 3.Cuneonavicular articulation 4.Cuboideonavicular articulation
The Dorsal Ligaments: The dorsal ligaments are strong, flat bands stretching from all 3 Cuneiforms and the Cuboid bone to the Metatarsals The Plantar Ligaments: The Plantar ligaments consist of longitudinal and oblique bands, with less regularity than the dorsal ligaments. The Interosseous Ligaments There are 3 interosseous ligaments connect the Cuneiforms with the base of the 2 nd and 3 rd Metatarsal
2 nd, 3 rd, 4 th and 5 th Metatarsals bases are connected by Dorsal, Plantar and Interosseous ligaments The Metatarsal Heads are also connected by a Deep Transverse Metatarsal Ligament. A narrow band that runs across and connects all the heads.
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.
Palmar ligaments: It is also known as volar plate. It contitutes the floor of the interphalangeal joint. Collateral ligaments: The collateral ligaments pass from the lateral aspect of the head of one Phalanx to the Palmar aspect of the base of adjacent Phalanx. Stabilize and prevent motions in the transverse and sagittal planes
The Plantar or Volar plates are fibrocartilaginous structures similar to the palmar plates in the hand; Due to the weight-bearing nature of the human foot, the Plantar plates are exposed to extension forces not present in the human hand. The Plantar plate supports the weight of the body and restricts dorsiflexion.
The plantar fascia is the thick connective tissue (aponeurosis) which supports the arch on the bottom (plantar side) of the foot. It runs from the tuberosity of the calcaneus (heel bone) forward to the heads of the metatarsal bones (the bone between each toe and the bones of the mid foot).
