Ankle injuries are extremely common in sports that have quick power surges, jumping and sprinting. So common that in the United States everyday 23 000 people need medical attention for ankle sprains.

Tibia: is the major bone of the lower leg and bears most of the body’s weight. The bottom portion of the bone forms the medial malleolus which is the inside bump of the ankle.
Fibula: the smaller of the bones in the lower leg, its lower portion forms the outer bump of the ankle. This is called the medial malleolus.
Talus: this is the top bone of the foot
Anterior tibiofibular ligament
Posterior tibiofibular ligament
Anterior talofibular ligament
Posterior talofibular ligament

Inversion sprain – this is the most common type of ankle injury because the lateral ligaments are weaker
Eversion sprain – this is very uncommon because the deltoid ligament is HUGE.
Symptoms and signs of an ankle joint injury:
Inflammation occurs when the ankle injury has occurred some blood vessels become lose allowing fluids to flow into the soft tissues surrounding...
