Common Injuries and Treatments
The Ankle & Foot
The ankle joint proper is formed by the ends of the lower leg bones and the foot. The two lower leg bones are the tibia on the inside and the fibula on the outside. These two bones join with one of the bones of the foot (talus) to create the ankle (talocrural) joint. This joint is primarily responsible for the up and down motion of the ankle (the movement of pulling the top of the foot towards the shin is called dorsiflexion and the movement of pressing down on the gas pedal is called plantarflexion).
Below the talocrural joint is the subtalar joint. This joint is formed by the junction of the talus and heel bone (calcaneus) and is primarily responsible for the side to side motion of the foot (the ankle movement of trying to touch the bottoms of your feet together is called inversion and the ankle movement of turning the bottoms of your feet away from each other is called eversion.
There are many other bones in the foot including the navicular, cuboid, three cuneiform bones, the metatarsals and the phalanges. The joints formed by these bones allow the foot to be rigid at times for weight acceptance and flexible at times to help keep your balance.
Injuries to the ankle are common and can involve the muscles, bones and joints, especially if trauma is involved.
