There are three types of sprains that can occur – inversion, eversion and high ankle sprains.
- Inversion Sprain – This type of sprain is the least severe and occurs the most frequently. Ligaments on the outside of the ankle are injured.
- Eversion Sprain – This type of sprain is the most severe, but fortunately occurs less often than the others. Ligaments on the inside of the ankle are injured and in certain situations, may be pulled away from the bony attachment.
- High Ankle Sprain – This type of sprain involves an injury to the large ligament connecting the two bones of the lower leg (tibia and fibula).
The most common symptoms associated with ankle sprains vary based on whether the ligaments are stretched or torn either partially or completely. There can be a range in severity from the ability to weight bear with some pain in the case of a stretched ligament to a complete inability to weight bear accompanied by a decrease in sensation with a complete tear.
