Talus

Calcaneus- thickest ankle bone

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

TibiaLocated on the

medial side of the lower leg.

**Femur rests on HEAD of the tibia

Medial malleolus-BASE of the tibia

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.
