BONES OF THE FOOT AND ANKLE

14 Phalanges Distal, middle and proximal phalanges toes(2-5) Great toe (1) Only has Proximal and Distal phalanges

Great toe On the plantar (bottom) surface of the great toe there are sesamoid bones

Phalanges Each phalanx is the size it needs to be for weight bearing purposes. Which is the smallest? Largest?

Metatarsals There are 5 metatarsals in the foot 1,2,3,4,

Base and head Each bone has a base and a head. The head is the superior aspect of the bone and the base in the inferior aspect of the bone. Head Base

The Base of 5 th metatarsal is called Styloid process Athletic trainers are concerned about this when taping an ankle.

There are 7 Tarsals Bones 3 Cuneiforms 1,2,3 Cuboid-connected to 2 metatarsal Navicular-connected to 3 cuneiforms Talus-must PF the ankle to be able to palpate it. Calcaneus-responsible for heel strike

3 Cuneiforms 1,2,3

Cuboid

Navicular

Talus

Calcaneus- thickest ankle bone

Tibia Located on the medial side of the lower leg. **Femur rests on HEAD of the tibia Medial malleolus- BASE of the tibia Medial malleolus

Tibia continued The top of tibia has medial and lateral epicondyles Tibial tuberosity- bump on superior middle aspect of tibia. The patellar tendon attaches to it.

Osgood schlatters A condition where the patellar tendon pulls on tibial tuberosity causing a bump in the lower leg.

Severe Osgood Schlatters

Fibula Located on the lateral side of the lower leg Lateral malleolus- BASE of the fibula

Common peroneal nerve Wraps around the head of the fibula. *MUST USE CAUTION WHEN ICING

THICKEST BONE IN BODY Rests on the tibia. FEMUR

Parts of femur Head-attaches to hip Neck Greater Trochanter Lesser Trochanter Shaft Medial Epicondyle Lateral Epicondyle

Patella Free floating bone located in the middle of the knee Patellar tendon and quadriceps muscle attach to it.
