Corpus: Foot skeleton

The foot skeleton forms the bony foundation of the foot.

The foot skeleton - excluding the sesamoid bones - consists of a total of 26 individual bones, which can be divided into tarsal bones (ossa tarsi), metatarsal bones (ossa metatarsi) and toe bones (ossa digiti pedis). The bones of the foot skeleton are held together by numerous ligaments and are connected to each other by joints.

Bones[Bearbeiten]

The foot skeleton is made up of the following bones:

• tarsus
  • talus
  • calcaneus
  • Os naviculare
  • Os cuboideum
  • Ossa cuneiformia I - III
• Metatarsal bones (metatarsus)
  • Ossa metatarsalia I - V
• Toe bones (antetarsus)
  • Phalanx proximalis I - V
  • Phalanx media II - V (the big toe consists of only two phalanges)
  • Phalanx distalis I - V

Furthermore, 2 sesamoid bones belong to the foot skeleton, the ossa sesamoidea pedis.

In clinical anatomy, the proximal tarsus is referred to as the hindfoot from a functional point of view, the distal tarsus as the metatarsus. The metatarsals and toes form the forefoot in this nomenclature.
