Arches of the Foot
4 Arches of the Foot
Medial Longitudinal
Lateral Longitudinal
Anterior Metatarsal
Transverse
medial border of calcaneus to the distal head of the first metatarsal
Medial Longitudinal Arch
includes
- calcaneus
- talus
- navicular
- 3 cuneiforms
- the first 3 metatarsals
Medial Longitudinal Arch
main supporting ligament is plantar calcaneonavicular ligament (spring ligament); area for “flat feet”
Medial Longitudinal Arch
lateral border of calcaneus to the fifth metatarsal
Lateral Longitudinal Arch
includes
- calcaneus
- cuboid
- fifth metatarsal
Lateral Longitudinal Arch
distal head of all five metatarsals
Anterior Metatarsal Arch
Runs across the first row of tarsals
Transverse arch
Gives protection & increases foot’s mobility
Transverse Arch
Includes
- cuboid
- cuneiforms
Transverse Arch
thick white band of fibrous tissue from medial tuberosity of the calcaneus to the proximal heads of the metatarsals
