foot and ankle anatomy

what strucutres are 3,4, and 5

3 - fibula (lateral and contributes to stability)

4 - tibia (medial and a major weight barring bone)

5 - lateral malleolus

what structures are 1, 8, 11, and 12

1 - calcaneus
8 - styloid process of the 5th metatarsal
11- anterior talofibular ligament (lateral ligament complex)
12 - calcaneofibular ligament (lateral ligament complex)

what structures are 7, 9, and 10

7 - talus
9 - metatarsal
10 - phalanges

what structures are 2, 6 and 13

2 - achilles tendon
6 - medial malleolus
13 - deltoid ligament complex

what structures are 14, 15, and 16

14 - navicular
15 - cuboid
16 - cuneiforms

what bones are in the shaded area called

• tarsal bones

what bones make up the talocrural joint

• tibia, fibula, and talus

what makes up the articulations that control foot movements and what movements

• made up of the talocalcaneal, talonavicular, and calcaneocuboid joints

• ROM = eversion, inversion, pronation, and supination

what ligaments make up the deltoid ligament complex

• posterior tibiotalar ligament

• tibiocalcaneal ligament

• tibionavicular ligament

• anterior tibiotalar ligament

what are the different types or arches

Longitudinal arch - starts at weight of the calcaneus and ends at metatarsals heafs
- supported by the plantar calcaneonavicular ligament and plantar fascia
transverse arch
- metatarsal bones

what is the purpose of the arch

• bear the body weight

• absorbs shock associated w activity

• provide functional space under the foot for BV, nerves n muscles to pass
